How many of you are seeing a pretty dramatic drop in tablet CPC prices? This month, compared to the last 6 months, is down dramatically. And this month compared to last month is a huge drop in CPC prices on tablet clicks. Not sure what's causing tablet CPC to drop so much for me. Advertisers can't bid separately (or opt of tablets) so that doesn't explain things. And it's not a huge influx of outside the U.S. tablets clicks - tablet prices have just tanked.
