This new algo still does not address the issue of duplicate sites. It pretty easy to find these guys when the have adsense ads using the same pub-id on two separate domains that are listed in the #2 and #3 position on page 1. Both sites are hawking the exact same product using re-hash from the main site. This takes up two positions for the same site owner and violates the GWMGL's. I wonder if we'll ever see any improvement with regard to removal of dup sites.
