Google does not spider every page of the web everyday. They can not keep a full accurate view of PageRank updated in real time. Google Guy has hinted at the fact that PageRank display updates are just that, DISPLAY UPDATES. PageRank is updated far more frequently when links appear from major websites which are frequently spidered by Googlebot. Recently a guy got arrested for an alleged Google extortion attempt. I was one of the few sites on the web that had wrote about the new AdSense autoclick software before the man was arrested. The lead editor of Internet News called me up and talked to me. He linked into my page about the subject in his article which appeared on Internet News, Earthweb, and even in foreign language translated websites.

If you search Google for SEO Book normally my home page lists at #1 and my buy now page lists at #2. Due to the articles linking to me recently appearing on the home pages of exceptionally powerful websites my autoclick software page now ranks at #2. This happened within a couple days of the articles.

As the autoclick articles fall into the archives of those major sites their link value will decrease, but for now those links are still adding a good bit of link equity into my site.
