Here's a fun one - I had some sites with one 728x90 ad block (that was in rotation with some affiliate ads) and one set of ad links that displays all the time. The ad links were getting a ton more clicks than the leaderboard, so I finally took the leaderboard off a couple days ago. EPC and eCPM is now through the roof on those link units; tons of clicks well over a buck a pop. Wish I'd done it long ago - who'd a thunk ad links could perform so well?
