I know this is boring if you you’re not trying to sell ads on a web site, but I found this info and needed to pass it on. If you’ve wanted to know how you should use ad networks to fill all of your inventory, or if you’ve ever tried explaining the process of optimizing eCPMs to anyone (CEO, your wife, your daughter’s 2nd grade class), you’ll know that it’s complicated, dry and sometimes seems a little like voodoo. I was speaking to the folks at PubMatic and they pointed me to resources (read: sales material) that will keep you from expending all of those braincells and creative juices writing it down. Check out a Flash animation here and download a fact-filled pdf here. Pubmatic is selling a solution to that claims to solve the problems managing remnant ad inventory. Haven’t tried the service, but they sum up the strategies pretty well.
