I have 1 leaderboard that shows the same banner practically all the time. Is there a way to have more variation in the image ads or a more varied mix of text/images?
I think you cannot do anything for this except blocking that ad via the competitive ad filter. May be iam wrong :|
I tried to use section targeting. It improved my text links greatly, but I still get the same stupid banner (and it is a REALLY stupid one) no matter what.
