This Site Rank Update/Export List History provides the dates that Google Toolbar Pagerank (PR) was exported. A long time between toolbar PR exports recorded within the below Page Ranking Export List was once 122 days (March 19/2005 to February 18/2006). By the March 28/2007 a long time between exports it’s 181 days (Apr 30/2007 to March 28/2007).
Toolbar Pagerank update, Google Directory Pagerank update, and Backlink updates by Sept 04/2005 are going to be known as Toolbar Pagerank Export, Google Directory Pagerank Export, and Backlink Export in this article. By 12, 23/2006 the Blacklink and Toolbar Pagerank export happen to be combined in this article (see explaining updates link below).
This better reflects what’s happening when there’s an obvious alternation in these 3 products. There’s only an export no update. The term update is going to be restricted to Formula Updates that will cause a general change in the internet search engine rankings.
The Toolbar Pagerank, Google Directory Pagerank, and Backlink exports don’t cause a general change in internet search engine rankings. Any ranking changes throughout the export from the values of those three products is a result of ongoing everflux changes – unless of course there’s a formula update happening simultaneously.

Page Ranking Export Table Definitions
TBPR Export: Toolbar PageRank Export – export of Real PR towards the Toolbar PR 11 unit scale (no more known as a PR update just as real PR is updated continuously and also the Toolbar PR change is simply an export of this updated value).
GDPR Export: Google Directory Export – export of Real PR towards the Google Directory 8 unit scale (no more known as a PR update just as real PR is updated continuously and also the Google directory PR change is definitely an export of this updated value).
BL Export: Backlink Export – export of the sample of the number of backlinks that is almost meaningless because it is merely a sample number. The dpi is visible using the link:worldwide web.domain.tld command (no more known as a BL update as backlinks are updated continuously and also the visible BL number change is definitely an export of this updated value).
