An update to the Google Directory has webmasters puzzling over an apparent discrepancy in PageRank scores.
For months, the speculation surrounded an apparent decrease in PageRank scores on Google’s Toolbar. It seemed the decrease in rank was connected to penalties associated with buying and selling links that passed on PageRank, a practice Google not-so-quietly condemned last autumn.
But what was more confusing was that though the toolbar scores were dropping, the actual search rankings looked to be unaffected. Google appears to have updated its Directory on January 8 along with PageRank scores that are significantly higher than listed on the toolbar.
Observers say the Google Directory update seems to be pulled directly from DMOZ, the open directory project. As a result, Barry Schwartz at Search Engine Roundtable joins others in discrepancy reports:
“…it seems like the Toolbar PageRank of this site is a PageRank of 4. But if you look at the most recent Google Directory update, this site appears to be a PageRank of 7.”
There are few theories posted about why this is occurring, Andy Beard explains how this could be problematic for advertisers looking to assess the true value of a website:
“It seems Google used their real dataset for PageRank for the Google Directory export, forgetting that they are telling their millions of users lies on their toolbar with manual penalties, which until now had no visible proof.
“Google have the right to do whatever they like with their search engine, but this is another major demonstration of how Google are manipulating public and advertiser opinion.”
