All forget 1 important thing: sales. Some PPS programs have ugly sites, which can convert 1:2000 or worse, but you will see 1:300-500 in their stats. They can start with 2nd page and if the ratios are still shit, they will start counting billing join page clicks, which normally converts 1:3-30(depends on the join page). And there is also difference with the tours, some great sites have 50% CTR to the join(2nd) page and even if they count 2nd page its still high, but other tours can have 10% CTR to 2nd page, so of course the ratios will look a lot better.
Only thing you need is to use your own script to count clicks and then check $$$ per click on the same traffic or similar gallery template(steady CTR)
