What is more profitable in general? PPC ads or affiliate links? Do you put both on your site or do the advertisements just make it less likely people will end up buying from your affiliate link? My first site doesn't make much with adsense so i tried a new one using clickbank but I have yet to get a sale, have been considering putting some adsense ads on it.
as far as u remember ppl dont like in your face advertising.. but strategically placed advertising, whether adsense or affiliate or both works and is not off putting... many websites have small sponsored by boxes.. that usually are affiliate links.. but they also have adsense and similar advertising.
