Some time ago PR big Update, let the user to PR has lost confidence, this time I talk about PR deep algorithm principle, let everybody understand what is PR,PR value algorithm principle overall based on the following 2 prerequisites.

11 pages are referenced several times, then it may be important;

Although a Web page is not referenced more than once, it may also be important to be referenced by important web pages, and the importance of a Web page is passed on average to the pages it references. This important web page is called the authoritative (authoritive) Web page.

2 assumes that the user initially randomly accesses a page in the collection of pages, then follow the Web page of the link to browse the page, not back to browse, then the probability of browsing the next page is the PageRank value of the Web page affect the PR value of the factors, the PR value is reflected from 0 to 10 of 11 values, On Google's toolbar, a horizontal green bar chart shows that the 0-level case is white. It is for the Web page, not the site, so a site's home page and internal pages often have very different PR value. Due to the Google market expansion process, the PR value of Chinese web pages as a whole is lower than the English page. For the Chinese site, with 3-level PR is the basis, 4-level PR to achieve the standard, 5-level PR is good, and 6, 7-level PR even quite excellent site. Of course, because the most direct impact of PR is from the link, so this rating does not represent the level of content, site content quality of the impact of the PR is indirect, long-term. According to the PR value of the algorithm principle, we know that the impact of a website (home) PR value of the main factors include

1 Import link quality of the website

According to the previous analysis of the high quality import link, the high PR value needs to obtain the link from the following website

Join the search engine classification directory and have joined the directory of the site exchange links

Get links from PR values of no less than 4 and related or complementary sites to your topic

Your links are now large, high profile, frequently updated important sites (such as news sources)

Sites with which you exchange links have little export links

With high content Quality website link (pr value rise potential big)

2 Number of links exported

According to the principle of PR calculation, because "the importance of a Web page is passed to the page it refers to," so in turn, too many export links within a page will potentially cause the loss of the page PR value. However, from the content point of view, the appropriate number of linked to the topic of the export links to the search engine to bring a good impression. Therefore, a page, especially the number of export links to the master, should take into account the PR value and keyword content between the two balance, that is, control the number of export links, to no more than 10.
