In early December some astute webmasters noticed that some of their longterm (in some cases many years) #1 or #2 ranking pages in Google now rank at #6. Just like with the Google -30 and the Google -950 penalties, some people will maintain this is fiction, but too many smart people experienced the same thing at the same time for it to be such.
Google’s Obfuscation of PageRank ScoresGoogle has a long history of deceiving webmasters, in order to push Google’s business interests and keep their search results clean.
Some of Google’s algorithms give sites a +30 type penalty which prevent the site from ranking better than #31. When Google hand penalizes sites it also tends to look the exact same way, with one exception.
When a site is hand edited typically it won’t even rank for its brand name related keywords. Assuming your site has at least a few links, I believe most of the automated penalties still allow mydomain.com to rank for mydomain. Although, over time, I suspect Google may change this, as editing out sites for their own brands hurts Google’s relevancy.
