Do Systematic Ad Tests, Get High CRT

"CTR is King, as far as I'm concerned. Do systematic tests of all the things you can control (# of ad blocks, size of ad blocks, color combinations, positions, etc.). All I can tell you is that when you take the time to do that, you might be blown away by how big a difference it can make. Get your CTR up into double digits and watch your bottom line fatten up nicely. " Swebbie
