Older and wiser heads assured me there wasn't (I'm still pondering that one ;) ) and advised patience. The second piece of advise proved right. Sites that had disappeared from Yahoo! are now back.
I switched the ads on the page that dropped off Yahoo to YPN ads... low and behold the site came back up to the top. It took a few weeks, but sure enough the ranking was back.
For awhile I was ecstatic about the YPN results on those pages. I was earning several times what I earned with Google on the same pages. Unfortunately the earnings for those pages has dropped back considerably being much more in line with Google's payout.
I do think Yahoo penalizes you for running Google ads... or maybe they penalize you for running Google Analytics...
