A system and method for achieving optimal advertising is disclosed. In Internet advertising embodiments, small quantities of experimental advertising banner designs are tested to extract valuable information from the experiments. One or more embodiments can also incorporate array mathematics to help select and analyze the ad design elements that improve the results (e.g., click-thru-rate, revenue-per-impression, etc.) of the overall advertising campaigns. Embodiments of the present invention can also utilize a process of identifying influential design elements, selecting and testing banners representative of such design elements, obtaining feedback, and analyzing it to extract information from the experiments about which design elements arc most important and which combination of design elements lead to the best overall banner. By providing substantive results via fewer test banner designs, the present invention decreases the costs associated with running advertising campaigns and otherwise improves the efficiency and success rates of an advertising provider.
