Several banners for a single ad campaign

Web Banner Tip #12 - Several banners for a single ad campaign
Unless you have done thorough research on your audience preferences and behavior patterns, its highly unlikely that a single banner would be sufficient for your ad campaign. I believe that you should start with 6-10 banners. You should keep rotating the banners and as the ad campaign progresses and you’ll come to know which banners are generating higher click-thru rates. It is imperative that you track the success of each banner in terms of CPMs, CTRs and CPCs
