]]>First Siam
Second short
Have you ever been able to identify Siam and British short? Probably, it doesn’t seem to work. This is because there are too few materials, and we can see that these two pictures can be extracted from each other with too few short features. What if we Siam short put 100 picture, the short put 100 picture for your reference, and give a Siamese or English is just a photo can be identified is that a cat, if not recognized, also has a 90% can guess may be right. So if you provide 500 pictures of Siamese 500, are you more likely to guess right?
How do we identify Siamese and British short? It is first summarized the characteristics of the two cats such as facial color, eye color, etc., when have a picture to identify short, we will see if facial color, eye color can be characteristic of Siam.
Will computers be able to identify the two cats as well, after learning how to identify Siamese and English short?
So how do computers recognize images? Let’s look at how computers store images.
The image in the computer is a pile of Numbers in order, 1 to 255, which is a black and white picture, but the color varies from three primary colors – red, green and blue.
In this way, a picture is a cuboid in a computer! A cuboid with a depth of 3. Each layer is a number between 1 and 255.
To get a computer to recognize a picture, you have to let the computer know that it wants to recognize the features of the short image. Extracting features from images is the main task of identifying images.
Here is the main character, roll and neural network.(Convolutional Neural Network, CNN).
The simplest convolutional neural network looks like this.
It is divided into input, convolution layer, pooling layer (sampling layer), full connection and output. Each layer compresses the most important identifying information and transmits it to the next layer.
Convolution layer: to help extract features, the deeper (multi-layer) convolutional neural network will extract more specific features, and the more shallow network extraction will be more obvious.
Pooling layer: reduces image resolution and reduces feature mapping.
Full connection: flattening the image feature, treating the image as an array, and using the pixel value as the characteristic of the value in the predicted image.
Convolution layer
The convolution layer extracts the features from the picture, and the image is stored in the computer according to the format we mentioned above (cuboid). First, extract the feature and how to extract it? Use the convolution kernel (weight). Do the following short operation:
You look at the left and right matrices, and the matrix sizes are from 6×6 to 4×4, but the size distribution of the Numbers seems to be consistent. Look at the real picture:
The picture seems to be blurry, but what about the size of the two pictures? It’s in the following way: same padding.
You add a circle of 0 around the matrix of 6×6, and then you have a 6×6 matrix, and why you add a circle of 0 is related to the size of the convolution kernel, the step length and the boundary. Do it yourself.
The above is a demonstration of using a 3X3 matrix on a 6×6 matrix. What does it look like to convolve in a real picture? The diagram below:
A 28x28x10 activation map (activation diagram is the output of the convolutional layer) is obtained by convolution of a 32x32x3 graph with 10 5x5x3 filters.
Pooling layer
Reduce image resolution and reduce feature mapping. How do you reduce it?
Pooling is done alone on each depth dimension, so the depth of the image remains the same. The most common form of the pooling layer is the maximum pooling.
You can see that the image is obviously getting smaller. As shown in figure:
A new graph is obtained by extracting the maximum value of 2×2 on the two-dimensional matrix of each layer of the activation graph. The real effect is as follows:
With the increase of convolution layer and pooling layer, the characteristics of corresponding filter detection are more complicated. As you accumulate, you can detect more and more complex features. There is also a problem of convolution kernel optimization, and multiple training to optimize the convolution kernel.
The following USES apple’s convoluted neural network framework, TuriCreate, to distinguish Siamese and English short. (first of all, I have been working late in win10 to reload the computer more than 3 times. The system should have WLS, and it is convenient to install turicreae under the enterprise version, MAC system and ubuntu system.)
First of all, prepare to train with 50 pictures of Siam, 50 long. The test USES 10 pictures.
Code :(development tool anaconda, python 2.7)
The data is placed in the image directory of the h disk, and I am installing ubuntu in win10, so the h disk is hung in MNT/down.
Test files :(x refers to Siam, y refers to short, so the name is to distinguish the cat type from the test pictures in the code)
test_data[‘label’] = test_data[‘path’].apply(lambda path: ‘xianluo’ if ‘x’ in path else ‘yingduan’)
The first results are as follows:
The accuracy of the training accuracy is 0.75 and the accuracy is 0.5. Well, it seems that the study is too little, and it will take three years to simulate the five years of the college entrance exam, which will increase the number of Siam and English short pictures to 100. I’m looking at the results.
The accuracy of the training was 0.987, the accuracy of the test was 1.0, and the accuracy was 1.0.
See the results of turicreate recognition:
Our actual picture of the cat is :(red is the type of the real cat – in the code, according to the image name, green is the type of cat identified)
You can see that the two are consistent. The cow forces the training data only 200 pictures, can achieve this effect.

What is content operation?
Content operation refers to a series of marketing activities related to content based on product content planning, content creation and editing, content optimization and publishing. For different channels, content operation has new media content operation (such as WeChat's content operation), content platform operation (for example, the content operation of Jane's book), etc. According to different business, content operation can be divided into promotion content operation, product content operation, user content operation, etc.

What is content operation?
Content operation refers to a series of marketing activities related to content based on product content planning, content creation and editing, content optimization and publishing. For different channels, content operation has new media content operation (such as WeChat’s content operation), content platform operation (for example, the content operation of Jane’s book), etc. According to different business, content operation can be divided into promotion content operation, product content operation, user content operation, etc.
The importance of content operations.
Content operation occupies a very important position in the whole operation activity. First of all, the content can establish the connection between users and products. The content can convey the brand value while also cultivating the user’s cognition of the product. Secondly, content operation is also a part of product service. Users can not only consume content directly, but also help users to consume products. In a word, good content operation is very helpful for users to pull new, retain and transform users.
The steps of content operation.
Using data-driven content to run content is an essential skill for marketers. Before creating content, we can use data analysis to identify the target users and set the right goals (for example, how many new users will we bring after our content is released?). And to a certain extent the impact that the content is about to have. To use data-driven content, we must master these three steps:
Data collection, data analysis, data feedback.
1. Data acquisition: understand target users and competitors.
The difficulty with data-driven content operations is that we must understand our target users accurately. Only by accurately understanding the target users can we output the content that is close to the user’s needs and arouse the resonance of users.
In order to understand users, we need to collect as much user information as possible, including users’ online and offline behaviors. For example, a user in the online search what questions, which topic is active in social media, like click what content and so on these online behavior are we to understand the need to collect information. User behavior data acquisition is to let us understand the user’s interest and interests, and the common behavioral characteristics of users. After that, we can group users according to their common interests and behaviors, and produce targeted content for different user groups.
In addition to collecting user behavior data, we also collect behavioral data from competitors, for example, what they developed. In what channel to promote; How many new users, how many transformations, and so on. Through understanding the performance of competitors, we can speculate about what keywords or subject to users more attention, the user has no interest in what content and to attempt to innovation, find the breakthrough point, to create some fresh content to win the user’s heart.
The purpose of data collection is to better understand target users and competitors. We can use these data to think about how to add value to our brand, how to produce differentiated content to attract users.
2. Data analysis: identify the most effective content promotion channels.
By collecting user behavior data and competitor’s behavioral data, we have a very deep understanding of when and where the target users are and what they want.
After we have produced targeted content, then it is how to promote it through the most effective and influential channels. In a blog to share is far from enough, no matter how much we output the contents of the user requirements, if the user had never seen these content, then we are purely a waste of time and energy.
There are many channels for promotion, such as email push, paid-for display advertising, big V cooperation with large impact on target users, or simple repeat marketing. Regardless of the promotion channel, we need to analyze target user behavior data and competitor behavior data to determine.
Data analysis can prevent us from promoting blindly. We can find out the best distribution channels for user feedback by analyzing the different performance of different content distribution channels.
3. Data feedback: prove the value of content.
After content output and promotion, we evaluate the content of our output and prove the value of our efforts.
How does the user interact with our content? Does our content cause a lot of discussion? What actions do users have after they have access to our content? · such analysis can give us a clear understanding of the value of content.
It is difficult for some brands to set the return on content investment, but we can describe the impact of content through proxy indicators. We can use different scoring systems to evaluate the participation of different stages and compare the effects of different content modules. For example, click browse content 1, and further participate in thumb up 2, collect content 3, share content 4, and then evaluate the purchasing habits of different scoring levels. Ultimately, we can figure out the relationship between these scoring data and sales data. The higher the sales, the greater the value of the content we produce.
Summary
The success of content marketing is no accident. The key to the success of content operations is the ability of operators to properly manage and use data output to be beautiful and to guide participation and transformation.

]]>How do we get the push messages to the desired effect?APP operators must pay close attention to the behavior of users, have a clear preference for users' interests, and push the content of interest to different groups of users at the right time.The perfect push messages are valuable to the user, which can help the product to improve the user experience and increase the user's liking.

How do we get the push messages to the desired effect?APP operators must pay close attention to the behavior of users, have a clear preference for users’ interests, and push the content of interest to different groups of users at the right time.The perfect push messages are valuable to the user, which can help the product to improve the user experience and increase the user’s liking.
Who: Object
What: Content
When: Time
Where: Situation
Why: Reason
Figure out these 5 Ws, then we can push messages satisfying users’ need.
1. Why: Why do we push this message?
“Why” always comes first, with every push message having a clear goal — to make the user login for the first time or for the user to upgrade?Not only do we need to know the target of the push message, but we need to know what behavioral data we want from the user.These behavioral data are used to measure the impact of push messages on users.For example, after the user logs on to a social APP for the first time, it will receive the following information, which is the push we made to get users to improve their personal data.
2. What：What do we push?
The content of the push messages have the following three characteristics:
（1）Targeted:
Sometimes small details can play a big role.In the example above, we added the user’s name before the message was sent to the user. “Hi, XXX, welcome…”Instead of sweeping to the point: “welcome…Plus the name makes the user feel more approachable.
（2）Ensure relevance and timeliness:
Push messages must be timely and highly relevant to users.Netease news, for example, is pushed to the user’s nanjing tomorrow weather news, reflects the correlation between geographical position, this message is to push on Friday afternoon, Saturday’s travel plans to give the reference for the user to remind, the right time.
（3）Accurate and rapid direct user pain points:
The user’s time is precious, and the message we push must get the user to the maximum value.Do not push spam messages to users, or do not match the user’s needs.For example, messages for users who don’t have a car.
3. Who: Who are we going to push the news?
The push message object cannot be cut and cut. We need to divide and manage the user through user behavior data.When it comes to user behavior, here are a few more common user behavior analysis platforms, such as friends union, baidu statistics, etc.But these SaaS platforms also have problems, and the raw data is difficult to export, and the data of their own products cannot be owned by us.It is also easy to recommend Cobub Razor, data private and backstage construction.
Different push messages receive different recipients.
We provide personalized news feeds based on the user’s behavior habits, preferences and so on.For example some music APP users to listen to music for different style, favorite star and collection of song single push related update alert, such precision push has greatly raised the proportion of the user to open the message.
4. When do we push the news?
（1）Time of day:
Can select the user free time, such as before going to work in the morning, at noon to eat, after dinner, specific choice which push period, can according to user’s use time was used to determine, in short not to interrupt the user when user busy or rest.
A time period for users of a financial app
（2）Push frequency
Too high push frequency can result in two kinds of results — the user clicks on the push and immediately turns off, or the user simply ignores the message and doesn’t even look at it.The number of push frequency should be determined according to the type of application, generally speaking, the social App can be pushed daily, the information class can be 3-4 times a week, the tool class 1-2 times a week.The number of times should not be too much, otherwise the user will not open up, and probably close the message push, even uninstall the application.
（3）Local time:
Push messages need to be determined according to the user’s local time, this needs us according to the user’s location to determine if your users from all over the world, Beijing time at four o ‘clock in the afternoon when Washington is at four o ‘clock in the morning.If we unified Beijing time to push the news, users in Washington would be disturbed.
5. Where: What situation are we pushing in?
Push scenes can also affect the effect of push messages.We need to consider where the user is when the push message arrives, what he is doing, or what device the user is using when he receives a push message.
We, as users, receive a lot of notifications every day. For example, the taxi app will push express coupons for me on Friday after work.The group purchase app will push the group purchase information of the restaurant near me at mealtimes.If the user is in a disturbed state when they receive a push message, then the user will not be able to look at the push message and take action that we expect.
The messages in the application are pushed based on user behavior, so the effect is better.Regardless of the user, lie sofa eating, no matter the user on the PC, mobile end, as long as we clearly understand the user behavior, according to their behavior push related news, the user is there is a strong possibility we expect action.
Conclusion
The perfect push message must be pre-defined by 5W.Through 5W, we make clear the target, content, object, push time and scene of the push message, so that the user can see the value of the push message to the user.Pushing is the best user touchpoint, and it’s more important to make a thoughtful product that fits the user’s habit than it does daily.
]]>Outline of this paper is illustrated below:
A touch, precision up to the user, the exposure is large enough
1. The advertising precision
Part of the listed companies advertising expenses (data source results)
Product is completely no advertising, from the table we can see that even have won 15 international gold prize of 1915 China’s national drink moutai also need large amount of advertising.According to Wind information data organization, according to data of 2014 listed companies in China a total of 65.929 billion yuan worth of advertising promotion cost, even the industry giant AD is also in constant, increase the user’s perception of the brand, we have what reason to expect no money input can be a guest?
Advertising is essential to promote contact means, advertising are accurate enough, blind pursuit of big traffic platform as part of public money to throw distance platform for the small and medium-sized, frequency, cycle, small test results and accuracy and hard.
Here lists online, by the way of the mobile Internet traffic on the channel (incomplete)
Decision must be tested before big advertising, not after drop test, never know one stage which the flow of a platform is the high quality, the most suitable products.The direction of the big, big platform flow and spread, more suitable for search class advertisements;Vertical class platform also to consider the industry each competing goods delivery situation, on a vertical platform and a number of conversion were rare.
In addition to the online and offline advertising, advertising metro bus station, district school board, medium rolling screen, mall office building elevator and window, etc., can be the choice of offline advertising.
Case study:
In this play amount exceeds 2 billion douban 9.1 distracted in white night after fierce, standing and love money into two P2P creative advertising with the plot development, is said to be a price is 1 million, if is to pull a new guest, the advertising is not precise, of course if it is in order to expand the brand influence is understandable.
In contrast, another financial companies advertising (to brand name) :
Advertising objective: power, an online financial low cost access to high quality customers
Advertising background: an online finance is an Internet comprehensive service platform, with excellent and professional service ability, comprehensive strength in numerous financial wealth management services in the best posture.At the same time, as the Internet blossoming in the financial services agency, the rise of consumer finance financial guest cost rising, so how to accurately for the guest, low-cost new is that they desperately needed.
Target: effect of guest oriented, ROI more than the industry average.
Delivery period: March 2017 – June 2017
Financial management target groups: 20-35 years old, bachelor degree and above in group of high quality business people, crowd of finance and economics, finance, young consumers.70% of men, women accounted for 30%
Delivery types: finance, news, web portal, PC;Automobile, IT, education APP side.
On the implementation: through data analysis, they found that the target audience to pay attention to the weather every day, lest delay flights and choose to drive or take a taxi to go out;At the same time, they focus on news of finance and economics dynamic, care about their wealth accumulated depreciation and investment opportunities;Among them, the male money users generally focus on sports, sports news, have a favorite sports star and the team, and are willing to go to the scene to see a ball game.To via “weather”, “sohu news, tencent news”, “sina sports channel” to try, the results showed that the financial news of user intention is very strong, and then to financial news website and APP advertising.
In conclusion, advertising to analysis the behavior of the target user, now almost every Internet user is transparent, find some user behavior and its platform, the correlation of the test, according to the effect of increasing drop ratio, and control the cost of the new guest as possible.
2. Artificial precision touch up to push forward (online and offline)
Don’t really have money for advertising?That can only be human flesh pull customers, of course, AD is rich, artificial way also is very good, can more direct understanding of their products in the market reaction.If precision is a guest, not brand shaping, artificial forward and to push, should let the contact information of target users, rather than the cast the net wide and full.
Parking APP promotion, for example, the famous American traffic information data company Parking INRIX is among the first to launch the software, it is a Parking assistance service phone APP – “INRIX On – Street Parking”, they offline promotion scenarios have a “Street intersection”, “village office Parking lot”, “brand auto repair shops and stores”, while On the road to promote only choose private car, rather than a bus and taxi.As much as possible to the parking lot talking to property on the parking lever to promote cooperation, if not to push in to the parking lot during the rush hours.
To sum up, start doing promotion will be thinking about how to be more rapid, more accurate for the guest.
3. Spontaneous for users to share
In the new users at the same time, don’t forget the old users to the new role.Users can share, spontaneous reward can also be affected by platform to share, means, though different, but the result is the product to share with people around you.
On the users to share this topic, the activity box running clubs a “humble one activity, but it can achieve user viral growth” in a case I feel very fit, quote here, good ideas worth repeated exposure.
Users in the process of using the APP, meet interesting things, will share it.Worship at the bike just to market when using, we have to try.At that time, often in WeChat friends see friends to share your trip, or even a friend sent than the number of travel, riding time circle of friends.The sharing behavior of users spontaneity, in a short period of time for the bike has brought a lot of users.
Users find products is very good, the spontaneous products to share with friends.Product with payment for knowledge is the APP and NuMa APP on the sharing of product design and have such different, inside get APP, you can see the “recommended” [get] to friends this feature, users can according to their own requirements, generate posters, share with their friends, or is a key to directly share to their friends.And NuMa APP without this feature.
Share button in addition to the APP itself, users will also be spontaneous recommended in the chat, said didn’t stick to force others to read, for example, I would recommend “netease snail reading to her,” keep reading every day at least 1 hour, 1 hour later have no you want to read permissions (unless published a book review, if she published a book review, she gradually habit even fell in love with reading it).
Also there will be the UGC in the APP is very good, a picture, a sentence, an article is very touching, users will spontaneously to share.Such as netease cloud music, white space, everyone is the product manager, etc.
In addition to the users to share, spontaneous and induced by interests users to share, such as the product of spell group mode, Meituan hungry? A red envelope, drops Uber bus ticket incentive mode, etc., basically all consumer, financial APP users share incentive mechanism.
4. Different industry flow swap
Traffic exchange platform between cannot have direct conflict of interest, and to have the certain user overlap.In the absence of expense cost, take platform has its own traffic and conform to the standard platform to exchange flow, look for the best personal connection to the head company, with their cooperation, to talk about the flow of other home will have a better chance of cooperation.
Refer to baidu encyclopedia (the world’s largest Chinese encyclopedia) explanation for swap “flow”, which has described concepts and technical way of the cooperation of very clear, there is no need to do.
Case study:
Remember qihoo 360 Lou easily share their traffic exchange case, citing “Lou loosely blog” video search products business case: at first I did a lot of preparation work, want to how can to promote the flow of the product.First of all, I some of the traffic data analysis before cooperation.Put some effect is very poor cooperation stopped, only keep two flow effect is done, so I will take a lot of traffic to do swap BD position.
First of all, I would like to collect a lot of traffic exchange cooperation is willing to do the entertainment sites contact, and then a a to talk about, our product has less traffic at the beginning, since less change.But light on BD position, will never be able to transfer flow rate higher.Because access to video search users, mainly come in search of the video, can click cooperation links to sites on the BD position will not too much.
Then I thought of video search the features of this product, visit our web site users will eventually run into some video sharing website, such as “youku” “potato” cool “6” and other sites.Why do I want to go to their flow, should let these sites also to our BD, return to our traffic.
Then I put ALEXA1000 name at the time of video sharing site to talk about it again.At first two private relations and good video sharing site agreed cooperation.
Is better to talk with the back of the case, I’ll tell some video sharing sites, so-and-so video website also cooperation with us, and when a lot of video sharing sites also have do and some entertainment website traffic exchange cooperation.We are video search traffic more targeted in the past, if entertainment website can cooperation, it should be more cooperative with us.
When the video sharing site cooperation policy is you give me 1000 IP, I will return you 2000 IP.The more traffic in cooperation with us, they are more cost-effective.So when ALEXA1000 within the video sharing site nearly eight all have cooperation with us, and several of them were tens of thousands of IP traffic exchange, such as “youku”, “6”, “popcorn”, “mofile” and “mating” is the main partner.
Was the same kind of video search site also has several, such as “love asked video search” “yahoo video search” video “baidu search” because they haven’t asked the video website return flow, so I went to talk to the video website traffic exchange cooperation, has the certain difficulty.So I through the video search products features, give A video website over flow guide to video website, B B video website traffic guide to C video website.Cooperation with video sharing site, traffic.Flow rate of the exported to BD position also more and more, I also with some entertainment website also increased the swap.
Do remember the highest peak, one day there are hundreds of WPV, than when I took over turned over several times.And it is supported by no company resources to do, let me feel a sense of accomplishment at that time.On qihoo video search do promotion experience, has also been think is the most happy in my career for a period of time.
5. The media exposure
Tencent business friend once said:
“Many start-ups have no resources, voice is too weak.Sometimes, clearly project is good, but the spread of the articles are not attractive, not suitable for platform to report.”
I usually read product report more platform is a “dark horse”, “the tiger sniffing net” and “36 kr,” they reported each time all is around the story of the founders, thought to packaging feelings;By analyzing the good parts of the product or service differentiation, the sweet high standards of service, complementary advantages, founder of the team (in the industry has a strong professional ability, have a sharp insight to market) to expand coverage, etc.
Most of the time of media resources and it is not how much you pay, media platform also need high quality content material.They want those ideas, attitudes, dry entrepreneurs, they would express themselves about the industry, about the market, on the understanding of the user.So, good PR, first not ask what resources, but how do you think of PR, how to understand the people who help you do the PR.Otherwise, give you more resources, with no eggs.
6. Channel operation management
Because I am in the financial industry, the Internet, so it is understand that the assets of the financial sector is control in the hands of the mediation, financial platform in addition to the proprietary assets, but also cooperate with the mediation, thereby gaining assets, in this process, the platform can’t contact with real borrowers, contact only the mediation, industry present situation is so so, so, multi-channel operation management is quite important.
The so-called channel is provide business support for product transport users, partners.Financial platform to acquire assets (borrowers) and (investors) to get the funds, assets and intermediary cooperation in a wide range of industries, is to have them to provide various financial platform risk control into a standard customer;Also from the platform for various flow of funds, have long-term cooperation.
Constantly on a regular basis to analyze channel resources into effect, and to practical communication channels, defective rate is high to and channels of cooperation, in a timely manner to inform or to terminate its channels to prevent cash or brush single risk.
To attract users attention
1. The precise touch is the basis of the resonance caused demand
We always think about how to make the article more propagation force, how to give more people play the video H5 push, so large quantities of a variety of channels, but the effect may not be good, serious money spent, the effect not beautiful, so a lot of under pressure.Back to reflect on, we did not push the high quality content to the right people, with net fishing in the sea than to take a small mesh plug small fish touch xikou.
2. The impact of the visual or graphic feel
(1) the differentiation
Comparison of different things or to emphasize different aspects of the same things, and comparing, in order to produce a strong contrast.Contrast can be intuitive image, such as color, shape, texture, quantity, area, the direction of contrast;Can also be internal, such as properties, function, emotional appeal, connotation, characteristics, etc.Contrast to the elements, or produce the fierce conflict, or complement each other to be in harmony are an organic whole, constitute a strong difference teaching fruit.Contrast the creative purpose, is to highlight advertising, with a stimulus information affect the audience.
Case study:
(image from “creative design” oritive.com)
High contrast of cosmetic advertising: advertising scenario of graduated in 1969, a group of old man’s homecoming.Among the old woman thought the young woman in red face and figure, like their granddaughter, he showed confidence and a smile with the eyes of the other male students, female students embarrassing expression also contrasts, to fit the youth posture of the success of cosmetic surgery.
Contrast methods of the 2008 Olympic Games in the poster: the first is expression on the contrast, athletes is photography, the crowd is drawing techniques;Followed by color contrast, the athlete is color, is black and white people;Finally, the composition of a picture on the contrast, the athlete with the blank as the background, while the crowd numerous, very compact.The contrast condensed into a huge screen tension, the tension in the Beijing Olympic Games draws near, and ten thousand people shocked the aura of incisively and vividly express in my heart.
(2) zoom in selling point
The following several advertisements do you think of “soil”?
Malatang businesses: “mountain spring hot food, one hour in a pot, malatang also can be so healthy”
Native cafe: “flagship” let you eat to 40 years ago, the taste of chicken”
Organic tea merchants: “other people’s tea drink NongYaoWei, the organic tea to drink only fragrance” in our house
We eat malatang is worried repeat with soup pot, one with even more than a day?Native is missing under the modern feed for aquaculture has not used to the taste of the early?For black tea, poking fun at “bitter” a NongYaoWei?Our pain points is the selling point of merchants, the merchants selling point directly root of publicity, the customer first whether flocculant head, will at least to try.
Case study:
OPPO R11: “before and after 20 million, take pictures more clearly.”
Candy phone F11: “50 million pixels, than the more clear and more clear.”
Oppo direct selling point “more clear”, and enlarge the selling point “clear” candy “than more clear, clear, and specifically on the advertising of the oppo, both the interest, and has a strong selling point into effect, this completely easing the bit in competing goods ads, clothing!
(2) the connotation of the creative
We have seen a lot of creative advertising design, have to say, some slightly the connotation of the exotic advertising instead more impressive.In advertising design industry, creative seems to be spring never dried up, all sorts of funny, surprising, exaggerated, the connotation of creative ads emerge in endlessly.
Case study:
Your hand sanitizer: “one day what are exposed to, finally you do with your hands?Consider very fear.So, you will choose not to recall, or choose Siribuncha instant hand sanitizer?”.
NBA players: “sports need passion, need like animals are aggressive”.
Dry cleaner: “whatever he is lip seal, oil or wine stain, all get rid of all”.
3. Strong direct user demand, and puts forward the solution
Stamp in the user’s pain points is not enough, more simple and direct offer solutions, such both neither are hurting users feelings, and can drive the new product.
Double tenth a JPM medicine in 2016 with its logo and the advantages of the high recognition, deep recognition, advertising, with the attitude of a clever into its poster, can not only improve the visibility, and remarkable success.Pure and fresh style, warm words, let a person feel anything disgust, instead of multiplication.It not only box out of the users in the hand chop and the accident harm may occur in the daily life, also can in time out of their delivery to your door “20 minutes” solutions, is a sweet little quilted jacket.
4. Bold promises, eliminate user finally
Users never know “you” to want to know you, is a big step, she needs to break his heart security defense, this step will often turnover rate is higher.Chasing girls like you, the first meeting about what cinema or sparsely populated mountain, who will trust your own security to you?
We all said taobao fake goods, is the seller, return have to pay the freight, laborious also thankless, give a bad review and even cause the seller harassment, but there are many sellers in efforts to promote trust, use safeguard mechanism to reduce the order cost, make products and logistics cooperation at the same time bold promises, don’t believe you let users to trust their products?The gap between that began with a number of shops.
Light user demand, actively seek products
1. To provide access to, step up to
Careless mistakes never lost jingzhou made, very not easy to use content, advertising, attracted by any way users, but did not provide download the entry of the product, or make entrance can’t see don’t watch carefully, that this is a new, just made a brand publicity.
2. Reduce the user the opportunity cost
A user choose to do and not do an operation is a kind of decision-making behavior.In the perspective of economics, the decision-making behavior of “cost” is the opportunity cost.Users get products behavior brought about by the “experience is good”, “information security”, “will you won’t get involved in traffic”, “whether it takes a lot of time”, “will not work”, etc.Some we can be resolved, some are not solve, we reduce the user’s opportunity cost as much as possible, let the expected return is greater than the opportunity cost, the user access to products of this step loss can be reduced.
3. Participate in steps can decrease, it decreases
Pull the new process, to prevent the user when registered products deserted it, so make the registration procedure can be simple, simple, and even do tourists mode, don’t have to log in to enter the product of a few interface, to limit the function of the most characteristic after registration to use, to reduce turnover registration.
Case study:
WeChat reading is tencent products, have developed a “trial”, because there are a few people have this requirement, is they don’t want what WeChat friends to see their reading a book, or are not willing to take WeChat to land any products other than WeChat APP, maximum efficiency to optimize the attrition rate of the user login interface.Tencent did so in their own product system, we have what reason to let the user must log in?
4. With a hammer “affordable” limit use to conclude business
If the user has not registered, the couple’s exclusive discount and new methods, and if the user has already registered products, has been receiving limited-time discount can give users a sense of urgency of time, an impulse, which occurred some spending or transformation behavior (such as WeChat reading the length of the money to buy books, etc.).
New exclusive activity is almost every product standard, to do the page more impact, such as Vipshop preferential payment pages and pages of the countdown, can produce time sense of urgency, in the case of not fully considered just finished the action.Users also have the feelings of people, impulsive, also easy to change into rational conservative thinking, consider more long more conducive to action of product.

]]>First, let’s look at the overall structure code of jQuery 1-1:
(function (window, undefined) {
/ / construct JQuery objects
Var jQuery = (function () {
Var jQuery = function (the selector, context) {
Return new jQuery. Fn. Int (selector, context, rootjQuery);
}
Return the jQuery;
}) ();
/ / tools Utilities
/ / callback function list Callbacks Object
/ / asynchronous queue Deferred Object
/ / browser function test Support
/ / Data cache Data
/ / Queue Queue
/ / Attribute operation Attribute
/ / Events system Events
/ / selector Sizzle
/ / DOM traversal Traversing
/ / DOM Manipulation operation
/ / style operation CSS (computing style, inline style)
Code 1-1
From the above code, we can see that all of the code for jquery is written in an anonymous function that is executed immediately, called “self-invoking anonymous function”. When the browser loads jQuery’s js file, the self-invoking anonymous function is executed immediately, initializing the various modules to jQuery.
First of all tell me the advantages of the use the anonymous function called, to create a call anonymous function is equivalent to create a special function scope, the function of code won’t and existing functions, methods, and variables with the same. So the jQuery code will not be disturbed by other code, and it won’t contaminate global variables, affecting other code. There are two ways of writing anonymous functions, as follows:
/ / write 1
(function () {
/ /...
} ());
/ / write 2
!The function () {
/ /...
} ();
Code 1-2
From code 1-1, we can see that jQuery adds jQuery to the window object at the end of the invocation of the anonymous function, so that the variable jQuery becomes an open global variable, and the rest will be private. To the anonymous function called Settings window, and introduced to the window object, the window object into a local variable can be used as local variables) (the function parameters, such as in the jQuery code block access window object, do not need to return the top-level scope, can quickly access the window object.
Set undefined to the self-invoking anonymous function, because the special value undefined is a property of the window object, for example:
alert("undefined" in window); //true
The above code will pop true. In this way, you can undefined the value of the parameter undefined, because undefined can be overridden as the new value. You can try modifying undefined values with the following code:
undefined = "now is's defined";
alert( undefined );
Of course, this method is not supported in the high version of the browser, such as IE9.0, Chrome 17.0.963.56, and Firefox 4.0.
Usually in JavaScript, if statements are placed in separate rows, the semicolon (;)It’s optional to write, but it’s possible to omit a semicolon before or after an anonymous function call.The following code execution throws an exception:
Case 1
var n = 1
(function(){})()
//TypeError: number is not function
In the code above, the first pair of parentheses from the call to the anonymous function will be treated as a function call if the previous line of the anonymous function has not been added.
Case 2
(function(){})()
(function(){})()
//TypeError: undefined is not function
In the code above, the first pair of parentheses from the next line of the anonymous function will be treated as a function call if it is not added at the end of the first self-invoking anonymous function.So, when using a self-invoking anonymous function, it’s best not to omit the semicolons before and after calling the anonymous function.
The jQuery object is a class array object with continuous integer attributes, length attributes, and a large number of jQuery methods.The jQuery object is created by the constructor jQuery (), and $() is the abbreviation for jQuery ().If you call the constructor jQuery (), the logic for creating a jQuery object will be different.The constructor jQuery () has 7 USES, as shown below:
This time, I will tell you about the overall structure of jQuery.I recommend you to look at the principles of design and implementation of jQuery architecture in depth, and the technical points of jQuery are very detailed.
