I've try all kinds of banner ads and you have to get 1,000,000 of hits to get them to work. Now that I've send that. It's also where you put them and what kind of traffic are you trying to get. If you are TE or that kind of system you will not get very many hits... I've done ok with adbite but again I get some leads but no sales...
People have trained themselves not to click on banners, at least the standard 468x60 banner is useless.
Banners can work great... You have to make sure they are on very targeted pages and above the fold. Dave.
