How Trustworthy is Google PageRank?
pierrefar: There are two PR calculations: the internal one and the publicly visible one you see on the toolbar.Google uses the internal PR value as one factor (out of reportedly hundreds) in determining the rank of a page in the search results.The publicly visible one is, for all intents and purposes, an entertainment channel like, for example, Comedy Central. It is never an accurate reflection of the current PR value Google uses internally.So what to do? Use the Webmaster Tools and authenticate your site. The Webmaster Tools give you a ton of data about how Google sees your site which is a lot more valuable from a little green progress bar.
