| The answer, of course, is that advertisers care about cost over revenue, and when they can't get that, they care about cost-per-click, and when they can't get that they care about cost-per-impression, and when they can't get that they care about cost-per-estimated-audience. Nielsen demographics give a coarse guess as to who is seeing your ad. In contrast, keyword-targeted online advertising gives you precise ROI data that lets you hone your advertising campaign better than blasting animated gifs to users chained to their antequated, undersized and visually frenetic Hotmail accounts. |
