First introduced under PR,PR as Google founder to measure the level of the Web page a standard. is to do a major factor in ranking the page rank. When PR came soon after, there has been a website to increase the exchange of PR links. Development to now become some sites do not have content, only to improve the PR and desperately do link. Let PR lose the meaning of principle. Let Google founder did not think that the PR as the current Chinese webmaster Exchange link only standard. Was pushed to the top in China.
If Google wants to cancel PR, then see someone cheat will be canceled, where Google very early on this technology eliminated, not to stay today. But Google did not, because the PR existence has its value. At that time, Google's approach is the Chang PR update time. From one month to three months at a time. Google is doing this to tell us. The concept of PR is not wrong, the wrong is to judge the level of Web page technology is still insufficient, to be improved in one step. Therefore, Google so long time did not update the PR, does not mean that the cancellation of PR, but in the adjustment of the PR evaluation standard stage.
In addition, if Google really canceled the PR will bring any loss, we also come to one by one guess under: First of all, PR as an important Google logo, it is because he is a lot of webmaster only often pay attention to Google, these often internet webmaster will this search introduced to more friends, if this technology cancellation, webmaster will slowly forget Google. To the time Everyone rating site standards are certainly all Baidu indicators, such as Baidu snapshots, Baidu rankings and so on. Second, Google launched the PR page level, webmaster Exchange links are in accordance with this rule for exchange. If the PR cancellation, we exchange the standard of the link must use Baidu Index, which means that Google check the link is a disorderly state of the site exchange. To Google's rankings caused a lot of damage
