Page Rank Export List History

This Page Rank Update/Export List History contains the dates that Google Toolbar Pagerank (PR) was exported. As of November 20th, there has not been a Toolbar PR export for 53 day(s). The longest time between toolbar PR exports recorded in the below Page Rank Export List was 122 days (Oct 19/2005 to Feb 18/2006).
*Note: Toolbar Pagerank update, Google Directory Pagerank update, and Backlink updates as of Sept 04/2005 will be referred to as Toolbar Pagerank Export, Google Directory Pagerank Export, and Backlink Export on this page.
This better reflects what is happening when there is a visible change in these three items. There is only an export not an update. The word update will be reserved for Algorithm Updates which will cause a change in the search engine rankings.
The Toolbar Pagerank, Google Directory Pagerank, and Backlink exports don't cause a change in search engine rankings. Any ranking changes during the export of the values of these three items is due to on going everflux changes - unless there is an algorithm update happening at the same time.

Page Rank Export Table Definitions

TBPR Export: Toolbar PageRank Export - export of Real PR to the Toolbar PR 11 unit scale (no longer called a PR update as Real PR is updated continously and the Toolbar PR change is just an export of that updated value).
GDPR Export: Google Directory Export - export of Real PR to the Google Directory 8 unit scale (no longer called a PR update as Real PR is updated continously and the Google directory PR change is an export of that updated value).
BL Export: Backlink Export - export of a sample of the number of backlinks which is almost meaningless as it is only a sample number. This number can be seen with the link:www.domain.tld command (no longer called a BL update as backlinks are updated continously and the visible BL number change is an export of that updated value).
Algo Update: Algorithm Update - a major update in the Ranking algorithm that causes a large SERP change.
TB Program Version Change: Toolbar Program Version Change - a software version change to the Google toolbar that displays PR.
Days: Days between toolbar PR exports.
