According to his blog, Jim Karter made about $55,000 in February — $31,000 from AdSense alone!
Granted, this is across a large number of sites and he has 16 employees. Still, that’s a phenomenal amount of income for a single month. The way he split things up has me wondering how best to start increasing the revenue on my sites. He has good things to say about both AdToll and Kontera, so I’ll probably start experimenting with those.
