Google PageRank Update

Google is updating the PageRank scores as you read this. What is PageRank? According to Google:

PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at considerably more than the sheer volume of votes, or links a page receives; for example, it also analyzes the page that casts the vote. Votes cast by pages that are themselves “important” weigh more heavily and help to make other pages “important.” Using these and other factors, Google provides its views on pages’ relative importance.

Notice that in reality what is being updated is the toolbar score, which is the value that you see through the Google toolbar when visiting websites. The “internal” Pagerank, the one used for ranking websites on the search results, is actually constantly updated.
