Ratios For Your Sites... Hits .Vs Income?

I was wondering if anyone else tracked the statistics based on how many hits (uniques and raw) that your sites get based on how many of those visitors actually click outside of your site to generate you some form of income?

Right now im just finishing up working on some Sedo stats and discovered that every 10 hits i get to a sedo page, 1 of them makes me some kind of income by clicking on a link, be that $0.04 or $1.

I was curious if anyone else knew what their actualy hit > income ratio was not just what their sales conversion ratios were based on their sponsors stats?

Regards,
