1. Google Adsense. Google (external link) is the leader of online ad industry currently. According to its description: Because the ads are related to what your visitors are looking for on your site or matched to the characteristics and interests of the visitors your content attracts, you'll finally have a way to both monetize and enhance your content pages. If you have a lot of Asian or middle east traffic, this may be the best for you. Google pays you on net-30, monthly. (with minimum $100, if your account has less than $100, your balance will be rolled to next month).

But keep in mind, you can only put Google adsense ads on your main page, because the proxified page is NOT considered as your contents. If you put the ads on the proxified page, your account will be very likely terminated and you will get nothing. So, this is important for web proxy webmasters.

Then, how can you monetize from the proxified pages? The answer is AdBrite (external link).

2. Adbrite. AdBrite (external link) is actually an ad market, where you can sell your ad space or buy ads. You can choose to show network ads when your ad space is not sold. Adbrite pays you on net-60 bases. The CPM maybe not so good if you have only Asian and African traffics.

3. Paypopup. Paypopup (external link) is a reliable popup and pop-under ad provider. Actually, it is in the same big family of Clicksor. You can choose pop-up or pop-under; I would recommend pop-under and once per session so that it will not affect your visitors.

Of course, there are a few others, but some are not friendly to web proxy sites, e.g., RightMedia?. Anyway, as a start, you may try to put Google adsense on the home page, and put Adbrite on the proxified page, as well as the home page. Pop-under usually put on the proxified page only.
