Google has released an update to the PageRank values shown in the Google Toolbar. Matt Cutts, the head of Google’s Webspam team, confirmed the update in a tweet. The toolbar PageRank is a simplified snapshot of Google’s internal PageRank , with the toolbar PageRank values rounded to whole numbers from 1-10. The toolbar PageRank is updated every 3-4 months. PageRank is based on incoming links to a page and is one of the over 200 factors that Google uses for crawling, indexing, and ranking.
