*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. As of Dec 23/2006 the Blacklink and Toolbar Pagerank export have been combined on this page (see explaining updates link below).
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.
Read Matt Cutt's blog on What's An Update and his More info on PageRank, and the lastest Explaining Updates.
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.
