With the ccbill sites you can import the data into excel or something in few clicks. Others you can do it manually.
This is how I do:
At end of month or 5-7 weeks, I compare the sales (not ratio but $/clicks).
Since some gets more hits if I use FHGs etc or they count differently, I divide it into categories (1-5000 hits, 5000-10000 etc..)
Then I take each one who gave most $/click from each range, sort them with adding the rebills, and promote more of the best next month. The bad ones are pulled down on priority list and some are out.
Rest is subjective (new sites, new promo etc.)
It takes some time, but it is really worth it. If you do it right, its your best paid hours.
