Recently we had our site moved to the proper category in Yahoo!. After doing this and getting about 150 quality related links coming in, we have shot up to the top of the serps for our keywords. My question: Undoubtedly the Yahoo category listing helped our results in Google, which in turn helped our results in Google-driven Yahoo!. The help we received from Yahoo! with the Google results, if I understand correctly, are based on the PR and relevancy of our Yahoo! category listing. Wouldn't we also benefit from having another inbound link from a Yahoo! Sponsored listing? Even though the sponsored listings appear on the top of our category page, they also appear in a subcategory named /sponsors. Slightly lower PR but this should also help, right? Any help would be appreciated
