I've read a lot that banner advertizing isn't taken seriously by the majority of mainstream advertizers, but still can't give up completely the idea of using banners and experimenting with then. I don't have a lot to be proud of - I mean one one banner can perform better than another, but I've never been happy with either performance.
So I wonder if you use banner advertizing and how successful this is in your case.
Can you share any good sites and blogs with tips how to improve banners performance.
