With 5+ ad networks in my chain of advertisers on my larger sites, I've found that I frequently need to go in a weed out the ads that either A) I don't want to show because they annoy me or B) Don't pay enough. So was just curious how often you go in an do a little "ad maintenance" to keep your revenue at it's highest potential.
I only do maintenance when I see something that bothers me personally, like those annoying flashing ads. They make me want to have seizures, so I block them out. Plus, video and sound ads also go. I only tolerate those "shoot me" animated ads because I don't find them too bothersome. But as to daily maintenance, I don't do it very often, usually when I run across them myself.
