With proxy site, you can never tell because the ads are usually not as relevant compared to a legit and stand up website (static site). Anyway, good luck coz only you can know that.
its hard to tell actually. i have heard of proxy sites that generate less that 1% CTR and make a penny or 2 per click. and also i have see proxy sites that manage to get 3% CTR and makes as much as 5 cents per click. how much you get paid depends on your ad placement, how well the ads are blended in with your layout and content, where your visitors are coming from, and your page CTR. so just add your code in there and see how much you make. and one important thing to remember in case if you don;t know that already, you can add adsense code on proxy site but not on proxyfied page.
