This may be a newbie tip so the newbies can take it. When displaying affiliate banners on your site change the dimensions by 1 pixel (ex. 467x60 instead of 468x60) as most ad blockers look for the most common sizes. Do this for all the standard size banners. Some people are fucking clueless and have adblockers on (not on purpose) but still have cc and would buy online through a banner. Also what if some geek blocks your ads even though his dad loves to play online poker.. ya know.
