Growth Hacking really allows the user to quickly grow

Lei feng's network (search for "Lei feng's network" public attention): author of North Sea, from the calculation, public advertising (ID:Comp_Ad)

The saying goes, "good wine needs no Bush"; they also said, "wine is also deeply afraid of the alley." Then, they said, his wine not fragrant Bush is not deep, just get an abacus weave his magic skills, accountant, data scientists, wine can be sold. This is called data-driven rapid user growth, jargon called "Growth Hacking."

First heard about "Growth Hacking" this word, is in the last year a meeting of big data. (I forget, because now all the conferences are called data conferencing. ) When I got a Pocket full of negative energy, ready to power released a cacophony of comments, suddenly found a former Facebook engineers how to use data analysis to drive user product "Growth Hacking."

In fact, the engineer's speeches are one of the fair, and no advertising material is not a panacea, as also stressed that only products can improve retention rates. But then, this thing was out of shape, the Internet community there beliefs, data analysis is the Midas touch of magic. As you did for many years on the streets before the tabloid publicity: through the clothing acupuncture, can cause increased breast. As a code for so many years to deal with data and livestock, has said nothing on the issue, is the throat. Today we'll talk about, data analysis can really drive the rapid growth of consumer products?

For data and methods in the Jurassic and Cretaceous periods, the Chinese market, emphasized the role of data in General is a meaning of. Look at the data, rather than simple thanks to the wealth of useful, but then again again, data are really not made of money, does not mean that you believe in him and receive eternal life. Saint Cloud, "all number than many" useful in data operations in those scenes, how to make it useful, is the public's highly qualified readers to figure out the problem.

| Data management of the three axes

About using data-driven business growth, there have recently been many books and lectures. In fact, the way there is no mystery here, most data operations, methods can be summed up in the following three axes:

A, building conversion funnels

The so-called conversion funnel, is a step by step how your business users to cheat. Following; a few, you know at a glance:

Advertising: show-> click-> transform

Games: download-> activation-> retirement pay->

Sister: shaking it kissing dating->-> hand->-> bed

Regardless of the business above, can be broken down into a series of stages, after each stage, users are only part preserved. On every aspect of the funnel and accurately record data in order to analyze and optimize all aspects of the adoption rates, data operations infrastructure.

Second, multi-dimensional data report to find the problem

Common pain points in data operations, is an aspect of knowing conversion funnel through rate is low, but can not find the way to improve the. Common solutions, is playing fine data down to each dimension were observed, which often can be found on the product or system problems. If more than one dimension can be flexibly combined observation data into a data cube (data Cube). The funnel and Internet product operation the figure below data it doesn't matter, but the principles are the same.

For example, you find the ad click rate is low, which is found on the Chrome browser hits down the overall statistics, then delve into causes at the Chrome browser, the result is likely to be your Flash advertising materials directly to shield by Chrome.

The multidimensional data reports to locate and find the problem quite effectively, it is actually an efficient debug, is still a "taking" strategies.

Third, using a/b testing to guide product evolution

Is there any data-driven "attack" strategy? There are, of course, develop more products may improve, putting them on the line, who falls in the real data to decide. This a/b testing methods, tend to be all lies in the ideal can optimize the magic of good products, but also "better" one of the foundations of the theory.

Speaking of A/B system, but is not a simple thing. How to build both the accuracy and efficiency of the experimental framework, and write a long article, and we will not go into here.

The three axes above, for running a product is very important. But if you think you have this kind of thinking of data, you can use data analysis to make great products, it might as well wash sleep. Victorias Secret iPhone 5 Case

| Data operation can not solve the problem

Users on how to choose and evaluate a product, different areas have different rules. In simple terms, we can divide the products into rational and emotional products. For example, 3C, is typical of the rational products and apparel merchant, is the perception of relative products. Calculating advertising and recommendation system, although the technology stack have similarities, but the former is the rational products, the latter sensibility is much stronger.

For rational products, due to the objective of a stable and easy to quantify, data is one of the most critical optimization techniques. Advertising products, advertisers use its purpose, in order to obtain higher profits (of course this profit may be long-term or short-term), rather than to spiritual joy or pleasure. Thus, when two advertising platform is very big difference in the input-output ratio, clients will not be taken into account which experience superior, but did not hesitate to choose that makes more money.

But when it comes to sensitive products, it is not so simple. Remember the app just fire up when a wave from the side of the line officers will be diverted over the Internet analysts have Lotus at the mouth, with analysis of why the app is the end product of human social, why people still use QQ is the obstacle of the wheel of history. But last year, about the same analysts, and discuss why after the app transfer to mobile QQ users are having. So what is QQ good or micro-well? So problems at different times, under different users have different answers, and we're never going to such mobile IM products, give a general quantitative targets. Operating in sensitive products, since it is difficult to determine the optimal target is given, data optimization is the ceiling.

So, data operations under what circumstances could experience significant bottleneck? Generally speaking the following aspects.

Direction, product innovation cannot be obtained through data

A few years ago, there was a popular gaming company Zynga. It is said that Zynga's boss does not encourage innovation, adhere to the "-ISM", others copied game ideas, fast operating system with its own set of data ahead of the competition. What kind of data operating system? After all is a lot of a/b testing. Design: grass is green. Product manager says: no, green red data that counts! Then they really will flow into red grass and green grass in two configurations, if the data reflecting the Red meadow high user fees, then into the grass, red, botanists can go to hell! Relying on such a system, prolonged occupation within Zynga Facebook games top three. What happened to it? Answer is very clear – who know Zynga?

Zynga of decline certainly reasons many, but had to said only data on the of products operation thought is pushing one of: you of data test system again mature, also but on can make make grass coated red coated green such of tricks, and game of new mode, and new plot, and new design such of real innovation direction, not you has has data operation system on can has, even also cannot through data system to judge high. Take the iPhone for example, large screen interactive, Multi-touch, store these shine product features, painted by his faith in the products and insight, rather than markets and demand for research results.

Even when small short-term improvements, total reliance on an a/b test also does not work. We are able to pick out the data of a good plan, but if you only X/Y/Z option, then how do you measure a also can't get out. Someone asks: If all listed all the possible choice of products, data to choose? Operation is not playing mahjong, cards that combine the total number of children, will truly have the potential products need to have systematic and innovative thinking, product manager, coffee and others go to the bathroom on time trying, it is possible to find. Besides, even products like tiles, so clearly, when the product direction and becomes a lot, due to "dimension curse" exists, we can't accumulate sufficient statistical data to make decisions within a limited time.

Here actually have when it comes to the user product is truly the most important engine of growth, that is, product manager of insight and creativity.

Second, long-term user feedback it is difficult to judge

The Facebook engineer in his speech spoke of a vivid example: Facebook for years insisted on rigorous a/b testing framework decision if a new feature is been used in online systems. However,; what is it? He said Facebook actually PC version of Home for three years without any significant upgrades. In fact, the result is thought-provoking in itself: is Facebook becomes the end product of human social networks, and has been optimized to a global optimum and cannot be improved?

Conclusion clearly is not the case, I think even in that three-year abandoned many of the revised programmes, not necessarily manslaughter version: current a/b testing framework, data for only a relatively short period, and long-term trends and conclusions, if there is no faith in the product adheres to, the day it is hard to wait to come to fruition.

I heard about it from the traditional print journal rule: generally, the magazine for the first few months after the revision, all stink. And then a few months later, the new version may lead to significant increases in circulation. It can also be used as a case of short-term data deficiencies.

Three, game scene cannot use data decision

Game sex scenes are very common in the Internet products. For example, you might know, Explore and Exploit problem for Internet products, is part of stochastic-flow to explore unknown space, another part of the flow according to the statistically optimal decisions. Friends familiar with this area knows that if we have two E&E strategy is through a/b testing to determine their advantages and disadvantages. As to why, it is recommended that you settle E&E background knowledge on their own, when one questions the right now!

In addition to E&E, still many other game scenarios, such as advertising in mechanism design problem (that is, the rules of the bidding market how to formulate); another example has some social gaming strategy, are in principle not through simple flow can be effective a/b test.

Of course, understanding the game questions, needs deep product insight and macro-thinking skills, there are many product managers adhere to the rough hard, rather pretend that this problem does not exist.

| What do fast user growth?

Data this cashier, while essential, is not the anchor pin for user growth. It can really drive a product's users is growing rapidly, and by what methods? From the perspective of successful products in the history, here are some ideas worthy of note:

First, make a truly outstanding products

To put it bluntly, rapid user growth, the core issue is to do everything possible to make good wine. Product is good is really good, this is fundamental to all products and operations should be pursued. As mentioned above some of the data issues, excellent product manager's intuition and judgment, not findings consistent with short-term data. On the fork, adhere to the principle of product first, data feeds to the second sex, is more reasonable in the long term.

In particular, really good products generally are not based on the analysis of stock market came up, so there is no ready statistics can support. Pokeman recent fires Go, rapid user growth staggering, but I don't think it has established a comprehensive data operating system, even if there are not key to its growth.

Fast user growth in almost all of the great products, all from "good products" within the power, much like Google, Facebook, iPhone, such as taxi and broadcast applications.

Second, find a strategic promotion channels

What is strategic marketing channels? Simply put, are "cheap, full" channel. Many Internet users of the fast-growing, often in foot work. Victorias Secret Case

For example, the rise of cross-border e-commerce, and early they strategically a lot purchased from the Facebook traffic has a lot to do with it. And to this day. Facebook advertising prices have been pushed up a lot, it the opportunity isn't there any more.

In China, many of the fast-growing mobile Internet products non-BAT, most rely on pre-installed channels of this strategy. Manufacturers have pre-installed, operators have pre-installed, solution providers also have preinstalled. Pre-installed in the year cost of one-fifth positive spending today's products, today has grown into a big company.

Undervalued strategic channels keep a keen sense of smell, the rapid growth of the product is essential.

Third, using viral tools

Viral distribution, there are two classes, one is infected and one is a pyramid scheme.

So-called infection was induced and bundled installation through a already has a large installed capacity of products, by means of coercion or even secret operations, bringing another product to the user's Terminal is often more economical way. Even in the ordinary channels of advertising to do good results, for example: cleaning or security products on the move, often directly in advertising intimidating user "your phone memory low" or "your cell phone can be risky", users feel a daisy a tight, was installed.

Pyramid schemes are all familiar. After social networks, MLM-style promotional programme is more convenient. All kinds of variety group fight mode, and forwarded the draw mode, although it cannot be said to be pyramid schemes in the strict sense, the essence of which is to mobilize the masses the masses, this way if used well, will do wonders, who with who knows what.

Four, branding the users cognitive

Community awareness of the importance of this is lacking. Products stand to keep GE Uncle lying like that attitude can also earn money, core user awareness is critical.

In the Internet sector, people often direct communication to Minister creed, insufficient emphasis in brand-building. However, the recent success of companies like oppo, began re-examining the role of branding and user awareness. In my opinion, successful brand building user growth, may be fast and healthy.

Talk so much, it doesn't mean that data management is important, but rather to achieve rapid growth in product, in fact, there are more important things. All of today's Internet practitioners, to master the correct data management methodology, and data do not blindly worship teach religious. A popular and successful products, although the data operations indispensable, but to focus on core "wine" and "moved to the alley" on the two key points.

Experience can form a closed ring VR consumer Center is probably the best which

Lei feng's network (search for "Lei feng's network", public interest) by the writer Chen lianglong, Sting technology co-founder (app Dragon-plum).

Technical realisation

Any technology are some of the discontented genius or visionary entrepreneurs bring, can be a great product whether it's up to each and every user is attracted to pay for it.

There are many technologies for decades, but has been at best game no one played the awkward, is not found in the same way. The author had reviewed 20 years of smart home (20 years, it's a way to look at the smart home), is a typical representative of the industry.

Realisation of the premise is to form a closed loop of consumption, or more direct experience to form a closed loop, or will only be a minority party.

Take iPod as example, we assume that the jobs at the press conference and other makers such as Walkman announced the birth of a new product, and tells consumers how cool the product is, how many innovative technologies, iPod, could never succeed. IPod before the birth, Walkman, the biggest problem is not the product itself does not look good, but less downloads of the song, the song difficult, that this experience is not closed-loop, also can't set off a market. Turn iPod, download songs and quite easy to manage your songs, and supports up to 1000 songs, which let users have a good experience of closed-loop, access to the user is necessary. X-DORIA iWatch Case

Birth to the term virtual reality for almost 30 years now, whether we're going to analyze the VR technology – experiences closed-loop variable is now? VR experiences closed-loop should have three core conditions: Virtualization content, environments immersed and consumption than (my term for analysis: attraction/cost).

Content virtualization

Virtualization content became the bottleneck of VR, now there are also many users complain about buying equipment, but really attracted too few, leading to VR equipment use frequency is not high.

Virtualization content from digital to reality (XX video is typical) and computers and virtual content (as a typical representative of the game), really good content must be close to reality.

Now two sources are a problem: not enough realistic.

Mainly lack of reality of environmental quality data acquisition equipment, computer-generated and endearingly natural. Therefore all participants engaged in a night race, used the same strategy--rich content and then optimize content. Therefore have reason to believe that the virtual content of the conditions will soon be met, want to be VR, early layouts for content strategy.

Environmental immersion

Environmental immersion, mean that people can really integrate into the virtual world and perception as reality.

Environmental immersion is actually the real bottleneck in the VR broke out. To pass information through the virtual world of computer technology into the body and stimulate the senses have a real response. Simple says is one of vision, hearing, smell, taste and touch.

Can only do now VR Visual and auditory, and little sense of touch. In terms of vision, why 2016 can be VR the first year? Is actually a smart phone development.

Handsets that competition brings high performance, high resolution screen, and makes it cheap to screen. Advances in processor also can deal with high resolution images. Apple used in the iPhone's accelerometer technology, on the role of acting as a touch. Most important is a sense of touch, this needs to be based on the limited space layouts of different virtual scene of touch base. Like when you're in a virtual world while bungee jumping, in reality to create a weightless environment.

Consumption ratio

Than not much introduction, any technology into products, and be accepted by the user, depends on each user's consumption ratio that is attractive to users, and users have to pay the costs of. VR environment dipped this end already consumption is very low, such as the VR helmet, 3 blocks to the tens of thousands of product has, if you look at the article to try and pay may cost 3 bucks, then you most likely will take immediate action.

Cash, is to make the user experience into a closed loop.

VR to be liquidated, they should find a way to meet these three conditions, and form a closed-loop experience, taking note of experience will have a far higher priority than closed-loop size.

VR consumer centre

Zero Latency。 Located in Australia Melbourne VR Gaming Center, 2016 official Facebook showed 578 people to experience, and reviews are out. From the virtual content, chose to focus on the shooting game, their own technical team, and game makers.

Here are key points, shooting games is that they only do this kind of product, so in this area, it is easy to focus on the content, you can do better.

In terms of environmental immersion, not only by Oculus helmet, and developed a backpack-type host, and laser guns. This is actually very important, many companies trying to game it's hard to find a good model because the VR game is not as easy to buy as a 2D game products, advertisements, and users in their own home it's hard to have a complete experience, you need enough space to support.

What they do is transform rented warehouse, such a space can have a variety of scenarios. Prices are not expensive, the price of less than 100 Yuan, likely to be accepted. Done in three areas as a whole, the user experience is closed-loop, and is a very good experience, from the Facebook comments. X-DORIA iWatch frame

That entrepreneurs need to be VR, it is not possible to go to the already competitive equipment sales, I believe that at this stage in VR, the device itself up to how good are unlikely to get a better return, VR, it should form a closed loop experience, select a suitable area to do closed-loop, VR consumer Center.

Games can do, can do the training (virtual training projects such as firemen, soldiers, doctors, manufacturing, early childhood education), no matter which direction you choose, should meet the three conditions, so you are more likely to succeed.

Fifth Corning s gorilla glass 1 6 m height as you fall

According to foreign media, said, today Corning (CORNING) released the fifth generation of Gorilla glass, officials said the new generation of chemically tempered glass cover in wear resistance and ability to resist falling compared to fourth generation has improved. VR Shinecon glasses

Data shows that more than 85% of smart-phone users worldwide phone drop this will happen every year, and fell behind broken screen rate is quite high. In order to solve the pain points, the fifth generation of the Gorilla glass height safety performance has increased from 1 m to 1.6 m, 1.6 m, new glass intact with the cover dropping rates as high as 80%.

Fifth generation Gorilla glass materials using ion exchange technology, improve scratch resistance twice times, compared to other competing products (soda-lime glass) has about 4 times improvement. But due to increased crash resistance and wear resistance, Corning shall not shall not be compromised in the thickness, the thickness of the glass is 0.6mm, thick in the fourth generation of 0.4mm. Meanwhile, the fifth generation retained the melting technology, fusion and compression strength of the fourth generation of raw materials is certainly different. It is understood that the fifth generation anti-fingerprint Gorilla glass is also studying technologies, in an attempt to find some special layers or elements to achieve the purpose of fingerprint-proof. VR Shinecon glasses

There have been a number of vendor evaluation tests on fifth-generation Gorilla glass, Corning officials said, the fifth generation of the Gorilla glass first used in high-end phones above, is expected to close in the third quarter to come in the global brand on the end product, starting models are likely to be released August 2 by Samsung, Note 7.

3 15 mobile power unknown means 4 protection for safety

The consequences if used batteries are mobile power charging effect, short power life, poor stability, mobile power internal circuit is closely related to the stability and safety of the product. Any electronic products have a certain failure rate, if not enough manufacturers are not measures of protection configuration, does not prevent overcharge, overheating, overload and short circuit protection, ranging from easy to make batteries quickly scrapped, appears the products of combustion or explosion accidents.

Is a power supply or a bomb?

Lithium ion rechargeable battery's composition is as follows: battery + protection circuit board. This little battery protection circuit board is fundamental to guarantee user safety, although in theory, mobile power supply problems of the low probability of lottery prize, but there have been several cases. Many profiteers to cost savings through to the end, not just in the products on the circuit board to cut corners, moving some of the ridiculously low price of power there is even no circuit board, much less designed for mobile power supply battery of escort protection circuit board.

Battery protection board function there are two: 1. protect the batteries to prevent battery over charge, over discharge, excessive heat, extend the life of batteries, extending battery performance cycle; 2. minimizes PCB short-circuit, overload failure, the impact on the battery, lower batteries minimize the possibility of Burns, explosions. High quality mobile power products, in addition to the standard distribution core protection circuit boards, also on the choice of batteries, there are higher requirements--requirements of electrolyte in the batteries must be able to prevent explosion pressure relief valve.

Safety of the different types of batteries is also different. Polymer batteries has a flexible surface material, if short circuit cause battery bulges will crack and explode, so safe and 18650 batteries as used steel packaging, the most serious cases of explosion, and lots of mobile power currently on the market in order to reduce the cost of spell cheap, poor quality 18650 batteries,

If you buy the mobile power, even the battery protection circuit boards are not, it is a mobile power? Clearly is a ticking time bomb does not know when it will explode. If faulty, just like a time bomb around, why when we buy products of AMS products brand and price, not blindly pursue the cheapest.

Full range of circuit protection measures while the cost is not high, combined with cost no more than 5 Yuan, but see, for SMEs, a mobile power province 5 Yuan, 100,000 could save 500,000 yuan, is not a small profit. Layers of reduced security, and even a few cents of investment, unscrupulous manufacturers will not hesitate to save, of course, is also the personal safety of consumers may be saved. This safety issue, I would advise people not to be taken lightly. Saying not afraid of 10,000, but just in case, I suggest you don't buy too cheap mobile power, mobile power supply if you really out of business, you lose.
