From <a href="http://www.dogoodhq.com/publishers" rel="nofollow">http://www.dogoodhq.com/publishers</a>:<p>"The DoGooder does not block ads from being served on websites. Consequently, any CPM revenue agreements you have with your ad network / servers remains unaffected- yes, you still get paid."<p>I wonder what that means; they don't get into the technical specifics, but I get the impression that they will simply download the ads, and replace the ads with DoGood ads as soon as they're downloaded. This might be even worse: it messes up statistics for advertisers, and in the end, it will cause your inventory's value to decrease, thus resulting in a lower CPM value. Additionally, it gives advertisers yet another reason to push for performance-based (CPC/CPA) campaigns, instead of the CPM-based campaigns used for premium content nowadays.
