We are thinking of starting a banner exchange for a pretty good market. Has anyone had experience with this? We did notice that years ago banner exchanges were a bit more popular. We belive that we can get a vast amount of sites to join. Since all the banners point back to our site shouldn't it increase our SEO rankings?
Normally I'ld say that you shouldn't start one, but since it seems that you'ld get some traffic (=sites signing up for it), I'ld say why not give it a try. But you'ld also need to consider that banners are getting less and less clicks, which is probably the reason why they're not that popular anymore. Another thing: You shouldn't have the thought of improving your search engine rankings when starting but to help every user to get more traffic...
