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.
