Google updates its internal PageRank value continuously as the web changes and their index is updated. Only once every third month or so this value is exported to be displayed in the Google Toolbar.|
Multiple PageRank value may be used as an indicator of what will show when Google decides to export the PageRank values to the Google Toolbar.
This tool will query 35 chosen C-Class live datacenters to determine the pagerank (PR) value of the URL entered.
