The development process of the algorithm of decrypting search engine

We know that the search engine algorithm is unpredictable, that is to say, the search engine over the years is continuous development, continuous improvement. Perhaps today is such an algorithm, tomorrow will be another algorithm. This year this algorithm works, next year this algorithm is not the case. So some sites this year using this method to get the rankings, until the search engine algorithm a change next year, the keyword ranking dropped. So understand the latest search engine algorithm has become our vast seoer constant pursuit of the goal. According to relevant sources, Google's algorithm for the adjustment of about 500 times a year, on average, there are 1.5 times a day to adjust the algorithm, so today we discuss the development of search engine algorithm has great significance. Then we will talk about the search engine algorithm is how to develop, the most important thing is for the future of the trend of individuals also published views, we discuss together.

　The first phase of search engine algorithm: keyword density

Search engine at the beginning of the algorithm is the keyword density, I believe that the SEO friends are aware of this. Of course, search engine to judge the relevance of a site to give the ranking is to see the keyword density. So as long as the awareness of SEO friends, as long as their own web site or Web page to increase the density of keywords can get a pretty good ranking. It is because such people cheat is very simple, even more outrageous is to get the ranking of keywords. In completely unrelated to the Web page as long as the appropriate keyword can be ranked, a simple example, if a yellow site, as long as the homepage of the site to decorate a lot of SEO this word, you search SEO it can be ranked in the front. This greatly hurt the user experience, so the search engine to find ways to improve, so we came to the second phase of the search engine algorithm development.

　　The second phase of search engine algorithm: Hyperlink analysis

It is precisely because the keyword density algorithm is imperfect, so that the search engine represented by Google to improve the algorithm-that is, hyperlinks, that is, we often say outside the chain. Its principle is also very simple, Google is so judged whether a website by the user's welcome, that is, if your site is users like, then the user will link your site to the punishment to enjoy. Each link is a vote on a site, if your site outside the chain more, that is, others to your site more recognition, that is, we often say the vote. In fact, the development of this phase of the search engine although compared with the present is not very perfect, but the algorithm is more than the density of keywords n many times, Google is the first to put forward hyperlink algorithm search engine. This has also made the position of Google search engine today, so the search engine algorithm into the vigorous hair outside the chain era, of course, the chain era is not perfect, still not very good to meet the needs of users, so the search engine algorithm came to the relevance of the era.

　　The third stage of search engine algorithm: judgment correlation

It is because the simple hyperlinks still can not meet the needs of the vast number of users and easy to cheat, so the search engine for the algorithm has been related to improve, that is, to determine the relevance of a Web site and links. The relevance of the website content is to write with title, key words, description mainly. The search engine also determines whether your first inner page is created around a theme. It also determines whether there is a link between each page--that is, the relevance we say. I used to talk to colleagues about a topic, that is a website title is like a book's name, and each column is the directory of books. The first inner page is the book that explains it around the topic. The content of a website only in this form of creation is the most relevant.

After talking about the relevance of the station, the next is the relevance of the chain. Search engine just started outside the chain for the algorithm's most important to judge the quality of the site, the chain is in order to win, that is, the more the site outside the chain, its site to vote higher, you can get a good ranking. This appears a lot of garbage content, to search engines to add a lot of burden, but also make the internet flooded with a lot of junk content, so the search engine on the outside chain of relevance. In other words, we often say the quality of the outside chain. For example, we two sites are doing SEO, then your site to add a link to me, such links are relevant. Only such links are involved in ranking, if my site is to do SEO, your site is to do jokes, then you give me a link to the site, it is not related. Although we can not deny that the chain is ineffective, but at least it can be explained that the role of the chain in the rankings is negligible. This is the third phase of the search engine algorithm development, in fact, this time the search engine has developed more mature, the general user can still find the content they want, but this is far from enough, these algorithms are search engine a xiang willing. So what is the perfect thing to do? That is the user's decision, so the search engine came to the fourth phase of user experience first.

the fourth phase of search engine algorithm: User experience

In fact, the fourth phase of the search engine is our current stage, I believe that we are now deeply experienced. In the past the truth of the SEO industry "content for the king, the chain for the emperor" from the slowly ineffective. I have deep feelings, in 08, 09, 10 This three years to do the site keyword ranking is a patchwork of the era of the chain. Who's strong outside the chain who's on the cow X. I remember when I just learned SEO when bought outside the chain, ranking quickly went up, that three years is also selling outside the chain of spring, but now more and more, outside the chain for the keyword ranking is getting smaller.

Because the chain of the era has passed, the search engine algorithm came to the user experience the first time, that is, we are in the era, that a friend may ask how the search engine will know a site's user experience everywhere good or bad? Then we take Baidu as an example, how Baidu collects the data of each website? Baidu has a tool bar, Baidu share, there is Baidu traffic statistics. And as long as your site from Baidu search past the flow of Baidu is likely to statistics. If your site's bounce rate is very low, your site's users stay for a long time, the user's visit rate is very high, users of your content to continue to share. These are all the good things you can do to prove your site's user experience. All of these search engines are visible. And the most important point is the click Rate, if your site is ranked first in the search engine, and no one to click, then the search engine will also drop your ranking. But if your site user experience is good, ranked tenth, click on the person is higher than the first, the time to stay on your site is also very long, then no doubt that your site is very good, the search engine will put your site from tenth place directly to the first place.

Speaking of the user experience? I believe many friends will ask how to do a good user experience? In fact, it is very simple, you ask yourself these two questions can be. First, your site is not able to solve the user's problem. Second, your site is not able to attract users, let users remember your site, for the next visit. It's easy to say and hard to do. Here we need to understand if the user-shaped changes are analyzed. To cite an example, when the SEO just came out, even a related search did not, along with everyone's demand for SEO more and more, there has been SEO optimization, seo training, seo technology, seo tutorials, seo tools, urban seo and so on. If your site does not appear these content, can not meet 70% of users, then your keyword ranking will not be long. Remember the process of SEO development along with SEO this keyword has been walking over is "SEO is what this keyword", but now SEO is what has disappeared, there have been SEO tools in the word Baidu related search inside. is not no one to search "SEO is what" this keyword, because with the user's development mature, for SEO understanding, and then SEO this industry so big, so this keyword on the search for less people, and everyone for the SEO tool needs more and more big. Before many people do not understand webmaster tools that page how will rank the top of the major search engines, in fact, the principle is I said above, people for SEO tools to increase the demand.

If your site can not change the user needs, then you want to get a better ranking is difficult, even if your site today's ranking is very good, in this period you meet the needs of users. When the user needs change, if you can not change with the user needs of the content of the site to adjust, I believe your ranking will not be long. So a site ranking can be a few years unchanged in the Baidu home page is quite not easy, when some people drop the keyword rankings will find the reason to say is the search engine algorithm and changed, I found that many people into such a misunderstanding. In fact, the real reason is not here, but the user needs have changed, your site can not meet the needs of users. In fact, when a website problems and find the wrong reason is very sad. I often received some novice questions in the group said: My site is more than others, my chain of quality and quantity are stronger than others, but that is why ranked no other good, you give me to think of ways, I really can not find the direction of the effort. In fact, 80% of the people who are asking such questions do not understand the user experience. So when we were studying the keyword. We must first have a deeper understanding of the industry. Re-analysis of the needs, and then the content creation. Then it is based on the changes in user needs to the content of the site constantly change, always remember one, that is to meet the needs of users.

Finally, this article for you to introduce some of the search engine algorithm changes in some of the process, including the future development of some trends and we should grasp this unpredictable search engine, I hope to be able to do after the site when the role of a little guidance,

Thank you, the above content by 38 funny net http://www.888gx.com/original share, A5 webmaster net start, in fact, user needs change is a very worthy of in-depth discussion of the topic, I hope that we continue to explore, I also hope to communicate with you
