I've used Adsense for many years (since 2006, I think), but sometimes try alternatives with mixed results. I usually get a good bump when I first start a new system, but after a few months it drops down to match Adsense.

I'm currently looking at Ezoic:

[ezoic.com...]

I think that I would be a Level 4 or VIP Publisher. The system recommends using Ezoic CDN, which should (in theory) make everything run a tad faster... which, in my case, results in more pages per session, which results in more ads shown.

Any experiences or thoughts?
