If you’ve logged into Adsense recently, you may have noticed the following alert:

If you go into your “Adsense Setup” section and choose “Allowed Sites”, you will see an option that lets you block all of these external ad networks, block individual networks, or allow all of them (default). For those of you who are constantly on the lookout for new places to buy traffic (and fear the backlash of such an inquiry on Wickedfire), this could be a pretty handy little list.

Here I have copy + pasted the list (sort of), and even gone above and beyond the call of duty and hyper-linked each one to its respective site. Well, most of them. Keep in mind that many of these companies only deal with big clients, sizable media buys, etc. However, some do offer CPC advertising, such as Chitika, AdPepper, Pulse 360, etc. Also, I should point out that I’m not endorsing these networks in any way, as I have only used a handful of them personally. Now, without further adieu…
