I've been with FastClick for over a year now, and I've always been more than happy with them. I averaged a relatively stable $600/month with very few drops in daily revenue.
However as of about the end of January, my Pop-Under impressions have decreased by an unacceptable amount. I'm showing an average of 93% of all Pop-Under impressions being sent to defaults instead.
Meanwhile, other Pop-Unders from Casale are still doing very well and even better because of all of the defaults being referred from FastClick.
I've been in contact with FastClick many times about this issue, and in there long delay for response, they have yet to offer any solutions other than possibly that advertisers have selected to not use me as a publisher. However, 468/720 and Interstitial ads are still earning their typical revenues.
So, I'm curious... Have any of you noticed FastClick impression problems as of late? As for me, after a year of flawless advertising, I'm thinking that perhaps ValueClick is to blame for this.
Also, if none of you have noticed any problems, might you have any suggestions I can take to get my Pop-Revenues back up?
