Can you expand on this. What are behavioral display ads?

They're ads that are targeted by audience demographics (or even by an individual's buying history) rather than by keyword.

For example, a site about wines might be able to sell display ads for culinary tours in France and Italy, and a site about luxury travel might be able to sell display ads for upscale jewelry and other "lifestyle" products or services that aren't direcly related to travel. You see this all the time in the magazine world: Look at any issue of GOURMET or TRAVEL + LEISURE, and you'll find that probably half of the ads aren't about food or travel--they're for Cartier, Mercedes-Benz, Prada, and other upmarket "lifestyle" brands.
