Ok, Here's the deal:
PM me your URL, current average CTR (for one type of ad placement)
and how long have you been using the same ad network.
I'll evaluate the pages to see whether I can improve the CTR.
I'll charge $100 for one ad placement ($50 upfront for the commitment).
If the new placement doesn't increase more than 30% CTR, I'll refund your money.
If it does, you pay another $50.
The test will last one week, and you need at lease 1,000 impressions for the new
ad placement over a course of a week. I'll only take one site for now.
