Long are gone the times when Display Advertising consisted of incorporating banners in high traffic website with the hope that one potential customer would click an ad and magically appear on your site. In that obsolete model, an agency typically charges per CPM (Cost per Thousand) without reporting an ROI (Return on Investment) other than exposure. We believe that CPM is still valid but only if you can track the behavior of your customers once they have been exposed to your ad, and even better if your model allows you to estimate a CPA (Cost per Acquisition). Today with Demand Side Programmatic tools it is not only possible to get the best CPM but also understand which kinds of websites convert better for your product. We always take the time to understand user behavior, which allows us to recommend better Display Advertising, plans for our customer's projects.
