The full name of PR is PageRank, and it was granted a US patent in September of 200 1 year. The patentee is Larry Page, one of the founders of Google. Therefore, the Page in PageRank refers not to a webpage, but to a page, that is, this ranking method is named after the page.
PR is a part of Google's ranking algorithm (ranking formula), a method used by Google to identify the ranking and importance of web pages, and one of the important standards used by Google to measure the quality of a website. After mixing all other factors, such as the title logo and the keyword logo, Google uses PageRank to adjust the results, so that those pages with more "ranking/importance" can improve the ranking of the website in the search results, thus improving the relevance and quality of the search results.
The scale is from 0 to 10, and the scale of 10 is full mark. The higher the PR value, the more popular (important) the page is. For example, a website with a PR value of 1 indicates that it is not very popular, and a PR value of 7 to 10 indicates that it is very popular (or extremely important). Generally speaking, a PR value of 4 is considered as a good website. Google set the PR value of its website at 9, which shows that Google is very popular, and it can also be said that this website is very important.

PR is also true and false. Fake PR is PR hijacking. In order to get high PR in a short time, many webmasters jump their websites to a high PR website by doing 30 1. Note that when google updates PR, it will give this website the same PR value as the jumped website. But this PR is fake and useless. If the webmaster cancels 30 1, PR will re-evaluate and return to the original PR value. Moreover, hijacked PR will not bring PR score to friendship links. So, Anzone said, when you exchange friendship links, don't hijack website link exchange with PR.
