What are the main factors influencing PR value explained by Jining website construction company?

PR value is represented by 11 values from 0 to 10, which are displayed in the horizontal green bar chart of Google Toolbar, and white in the case of level 0. It is aimed at web pages rather than websites, so the PR values of the home page and the inside page of a website are often very different. Because of Google's market expansion process, the PR value of Chinese pages is lower than that of English pages as a whole. For Chinese websites, having a 3-level PR is the foundation, 4-level PR meets the standard, 5-level PR is good, and 6-level and 7-level PR are excellent websites. Of course, because the most direct influencing factor of PR comes from links, this rating does not represent the level of content. The impact of website content quality on PR is indirect and long-term. Jining Website construction According to the algorithm principle of PR value, we can know that the main factors affecting the PR value of a website (home page) are:

　　 First, the quality of imported links to websites: 　　

According to the previous analysis of high-quality import links, to obtain high PR values, you need to obtain links from the following websites:

◆ Join the search engine category directory and exchange links of websites that have joined the directory. 　　

◆ Get links from websites with PR value no less than 4 and related to or complementary to your theme

◆ Your links appear on important websites (such as news sources) with high traffic, high popularity and frequent updates. 　　

◆ There are few export links to your website in link exchange. 　　

◆ Websites with high link content quality (great potential for PR value increase)

　　 Second, the number of export links: 　　

According to the PR calculation principle, because "the importance of a web page is evenly transferred to the referenced web page", on the other hand, too many exported links in a page will potentially cause the loss of the PR value of the page. However, in terms of content, an appropriate number of topic related export links will leave a good impression on search engines. Therefore, the number of exported links on a page, especially the home page, should consider the balance between PR value and keyword content, that is, the number of exported links should be controlled, preferably not more than 10.

　　 Third, the number of pages of the website included by the search engine 　　

When discussing SEO, people pay too much attention to the ranking of core keywords and the performance of the home page, but often ignore an extremely important issue: the number of pages of a website included by search engines. The latter is also important in SEO. A website with poor ranking by using core keywords may get the top three rankings of its internal pages due to a large number of pages being crawled when users use other keywords. Because the keywords used by users in search are scattered, this situation often brings a lot of visitors to the website. 　　

Because the number of included pages directly affects the number of visits and PR value. The more pages included, the higher the PR of the home page. But it should be emphasized that the number here refers to the proportion of the number of included pages in the total number of websites, not the absolute number of included pages. For example, for a 50 page website, a 10 page list is used, and the list proportion is 1/5. For a 5000 page website, a 500 page list is used, and the list proportion is 1/10. Therefore, a 10 page list has a ranking advantage over a 500 page list. However, for each search engine, there is no relevant data on what proportion is good. 　　

　　 Fourth, the level of homepage PR 　　

Although PR is defined for web pages rather than websites, because every web page exists on a website and the home page is the core page for promotion, the PR level of the home page of a website also directly affects the PR of the inner page. Generally speaking, the PR value of each page of a website shows the following trends: home page, first level page, second level page, third level page PR decreases 1-2 levels per level. A deeper level may not be included in the rating range. Of course, if a deep inner page has many external or internal links, the situation is another matter. 　　

　　 Fifth, document type 　　

Google can index web pages and file types: pdf, asp, jsp, hdml, shtml, xml, cfm, doc, xls, ppt, rtf, wks, lwp, wri, swf. PDF documents are often important content or articles of websites. Therefore, Google's default PR for PDF files is naturally 3, which is higher than that for ordinary HTML files. Similarly, Google's PR to XML, PS, Word, Power Point, Excel and other types of pages is also higher than that of ordinary web pages. Therefore, it is recommended to make the valuable content of the website into PDF format. 　　

　　 Sixth, PR value update 　　

Google will conduct a thorough data update (dance) every month. After the update, the website ranking and import links will have some changes. However, its PR update time is generally delayed to about three months after the dance. The PR value of the website is relatively stable, and it is not easy to increase or decrease the PR level.
