Mention PR, do SEO people are familiar with, although for the layman is still a very unfamiliar concept. With Baidu and Google search engine algorithm constantly changing, a lot of SEO webmaster have issued a feeling: the role of PR has been very small! So what is PR? What is the function of PR? Today I would like to talk about personal experience.

1, what is PR? PR is also called PR value, is the English page rank shorthand, so the Chinese meaning is the page level, strictly speaking is a Google search engine on the site classification of a basis, reflecting the main site in the internet above a weight and importance.

2, PR is how to come? PR is a number between 0 to 10, the greater the number of the site's weight higher. Generally speaking, the PR of the website reaches 4 already very good, only some foreign sites such as Adobe official website to reach a 10.PR value has an algorithm, the formula has many kinds, but the most general situation is the network point to your site's super chain The more the better, the higher the PR value.

3, the role of the PR value. Now often hear many stationmaster said PR value did not function. There is some truth to this argument but it's not right. PR itself is only a Google index, and with the search engine algorithm constantly changing, the role of the PR value is reduced, we often can see a lot of PR 0 of the new station rankings are very close to the front, far ahead of some do many years of the site. However, this is only on the one hand, the PR value of the biggest role is embodied in the exchange of links when the link-most of the webmaster Exchange links is not still the PR as the only indicator to see? and the new station can be ranked very forward, usually due to a large number of High-quality anchor text effect- This is not back to the role of the PR value?

In conclusion, the effect of PR value on ranking is slightly reduced, but still can not be underestimated, because to get a good ranking, a large number of high-quality friends chain is essential, so the PR value is always a factor can not be ignored, after all, to all the webmaster all of a sudden change their ideas, it is a very long thing.
