The last PR update date is on April 01, 2010, until a few days before the update of PR, Google Update PR has lost the rhythm (as shown below), this period of time webmaster are in doubt that Google is not canceled update PR, but also to the webmaster to change the link brought trouble. The PR surprise update, no doubt the webmaster excited, but also some people like to worry. The PR of their own website Rose also followed the music, on the contrary on the worry. Here, someone will ask: how to optimize the site to enhance PR?

Google PR and Sogou rank the same point

What is the concept of PR in the end? PR (PageRank) is the founder of Google (page) was invented, also called page level, it is Google search engine ranked one of the algorithms, PR value range from 0 to 10. When it comes to PR, many people also think of the range of Rank,rank values of Sogou from 0 to 100. The similarities between the two are: they are the search engine of the page level of the decision, are the respective search engine ranking one of the algorithms. So how does a webmaster operate to suit the appetite for these algorithms? This is also the webmaster has been discussing the problem.

What factors are the PR value

Since I accepted the network promotion, once many times with peers to exchange how to improve the site keyword rankings, how to improve the PR value of the site, their own in these years of groping, more or less found that we all have a common problem: that Google's PR value is the only reference to the number of external links to the site That is to say, the more the direction of a website, the higher the PR value. And from my own experience, this view is one-sided, why? I would like to say in practical terms.

The site shown above (in the early January just changed the program, the data changes very large) is my responsibility for the two-year website, two years to go it alone, the station from the PR2 upgrade to the present PR7, through the above figure you can see this station's Google chain is only 61, this number is certainly not much, even can use less to describe, And why Google chain so little PR can also rise to PR7? Through this station I just want to prove a problem: the more Google outside the chain, the PR value is not necessarily higher, at best, can only say that the chain of Google is only one of the PR reference factors. Here, some people may ask, what is the PR value of what?

(a) The number and quality of the chain outside Google

Google's process of measuring the PR value of a website (page) is a very complex computational process. In the calculation of this PR value, a website (page) of the number and quality of the outside chain of Google is also a parameter in the calculation of the law, the PR value can be passed, the official also has a calculation formula. The theory of the concept is not much said, the analysis of the actual operation of attention. As a website optimization personnel, I believe we have exchanged links of experience, in our exchange links in the process will consider the PR value of each other's site, included amount, the amount of export links to the site and other factors. When exchanging links, if the PR is the best, if not, there is no relationship, we have to analyze the specific situation of the station and then decide, if the other side of the export link a lot of the final PR to the value of their site is very little, so we recommend to change the link to consider the number of export links, If you can get the authoritative website (such as university website) The quality of the outside chain is better. High quality is the absolute truth!

(ii) links to the website itself (inner chain)

Links to the site of the relationship between the PR impact of the site's ranking, or link relationship is a manifestation of Google PR, and for other search engines such as Baidu is not called the name of PR. Search engines have their own algorithms, and link relationships are also one of the computational objects of each search engine. Search engine principle: Spiders crawl, preprocessing, index rank in three stages, the operation of link relation is in the process of preprocessing. When a search engine crawls the content of a Web page, it is sure to calculate what links are on the site, what pages, what are the anchor text in the page, what export link and import link in the page, what text is used in the anchor text, these complex link relations, the search engine will one by one calculate and give the corresponding website (page) the link weight value. In general, the construction of the inner chain of the website is like building Cornerstone building.

(iii) Website content construction and update frequency

Search engine on the site of new content (original) extremely sensitive, in the content of the site to be updated to do have a certain rhythm. For example, a regular update of 5 articles a day, and can not update 20 today, and then one months not to update. Therefore, the site in the content update to do have rhythm, frequency, the site has a good habit of updating the search engine can be recognized.

In short, I personally think that Google's PR value reference standard is not only the number of chain outside the site, but also attaches great importance to the quality of the chain, it also includes the site, the frequency of updates, the quality of the site content (whether original), Web page content links (inside the chain, anchor text) and other factors, this will not be analyzed. According to the relevant literature, Google engineers also confirmed that the PR value is an overly publicized concept, in fact, the PR value of Google ranking algorithm is only one of more than 200 factors, and finally suggested that we should not be too determined to improve the PR.
