I'm a first time poster and noticed that Google Bourbon has really dropped the ball regarding re-directed search results and their duplicate content check logic. Since Bourbon, I've seen numerous top or first page search results display on topic search title and text, but re-directing to irrelevant Google Adsense pages. Didn't see this prior to Bourbon. Also, with Google's duplicate content "affiliation" logic that is new with Bourbon, companies can now virtually highjack a competitors website by spamming duplicate pages of that competitors site and redirecting results to their pages. Websites with top search result positions prior to Bourbon have now been relegated to "Additional Results" or "Supplemental" status, with this unscrupulous competitor grabbing the first position. This phenomenon is unique to Google and not observed in Yahoo! or MSN.
