Read about it 3 days ago on PPC Bully, and yesterday got slapped again. This time on topayforcollege.com . Prices for keywords position on first page doubled for Scholarship campaign, out of the blue. No changes made in last couple months on my site. Quality scores also dropped. Went from most being 7/10 to 5/10 and less.

No clue what to do about it, as no indication of what rules Google has changed this time.

Did learn one thing yesterday from reading Adwords terms and policies. Google only shows top 11 advertisers. If you don't qualify for first page ranking (within top 11) your ad doesn't show. So messages indicating you're not bidding high enough for first page actually mean that you're not bidding high enough to make the ad show, period.
