The impact of the search engine rankings only two factors, at first glance may be most seoer can not agree, think SEO to do too much, how can only two? But if you think about it, it is.

Guo Ping has a post, tell about his SEO experience, is not sure why wrote the first half, the key to the second half has been separated 4 months has not written ... It mentioned that he was the first time to do SEO, is to submit the site to Sohu, repeated several times, and then ranked up. This is the search engine in the early days, then decided to search engine rankings, in general, there is only one factor-the Web page and the search for the relevance of the word, after the short term relevance. Because repeated several times the word, at that time simple procedure thought the webpage relevance is taller.

At that time because the number of sites is very small, so the judge does not have a big problem, but with the rapid development of the Internet, the number of sites has exploded, the quality of the site is also uneven. The value of a page is high, it is impossible to just see how many times the Web page has been the number of key words such as simple means.

Then there will be--the weight of the site judgment, mainly in Google early on the importance of PR. PR is to see other sites to their own site "vote", the general vote more, that site is also more likely to be good. In general, this approach is correct, but then face the problem is seoer seo means, especially black hat seoer mass means, seriously affect the impartiality of the PR.

So the search engine ranking algorithm constantly change and change, making PR in the judgment of the weight of the Web page is less important, but also gradually, reducing the weight of the ranking impact.

Ideally, one day the search engine will return to the original, looking only at relevance, because its semantic analysis is likely to be strong enough to determine the value of the page. But at least for now, weights are sometimes even more important than dependencies.

So I think that weight and relevance are the only factors that determine the ranking of search engines. Of course, if you want to, you can also say that the search engine ranking is based on the value of the Web page, which is of course, but for SEO research is no big help.

Then will SEO impact ranking, divided into weights and dependencies, what is the use? This can be from macro to detail to analyze the nature of each specific SEO operation. For example, some sites, it has not done SEO, but because of years of outside the chain and so on accumulation, its weight is very high. Then, when we operate SEO, we need to focus on the relevance.

From these two points out, SEO will also be a very large system. Where the derivative to, that determines the level of SEO. However, no matter how long the contact with the SEO, I think should start from these two points, so do not learn the messy. After all, online most SEO tutorials, including me here, are thinking about what to write, nothing systematic. It's possible to learn better if you can get organized clearly.
