The rapid growth of ad networks is easy to figure out, says Jordan Rohan, founding and managing partner of Clearmeadow Partners at the OMMA Ad Net event in Los Angeles: Big profit margins.

Looking at some mid-level publicly-disclosed financial results shows a 47.3% gross margin for Interclick; 47.6% for Burst, and 45.0% for ValueClick.

“At the end of the day you are giving them half of you ad budget,” says Rohan.
