Has anyone noticed a signifcant drop in Yahoo Pay Per Click Search results during the month of November. Our campaign ads still have good rankings, but overall impressions and clicks are down at least 12%. I am just trying to figure out if its a Yahoo problem, or if prices are skyrocketing and we are not keeping up. This seems to be a trend this year, so I'd like to know if anyone else is experiencing the same problems. Google Adwords is still doing great.
