we can see that Google didnot update regularly. It is not very important for those webmasters who do not intend to make money from pr update. Some people said that high PR can bring visitor flow, it is not necessarily because I have a site with only one page content, it also reach Pr3, I haven’t seen many people to read the website, pr algorithm is based on many aspects and the results can not necessarily bring the flow.
