Welcome to WebmasterWorld Guest from 126.96.36.199
I look at my site today, and it is covered with PSA's instead of the ads I normally see. I check reports, and though my impressions are right on target, my CTR is down 200% (because WHO clicks on PSA ads?) and my revenue is 1000% down.
I started looking closer at the ads on the site, and when any DO how up, I get one instead of 4.
They must be having some sort of problem or something over at Googleplex.
I switched over to some paying ads until this is cleared up!
