You might have already heard about it. Adsense has started displaying ads from 3rd party networks. The ads are only image based so only those who are using text and image or only image will see those ads. My question is: has anybody tried it? Did you notice any difference in earnings?
I have not seen any earnings increase or decrease on a few sites i have image on. They might not have ads for topic so i am not sure if they have shown any yet
I've just updated my codes to allow this. Before I was using adsense in junction with RMX Direct and it was keeping my ecpm higher.
No I haven't tried it, because I have images disabled as they are generally low paying. I think it's difficult to find out unless you have a click tracking system in place like asrep. Link to the story http://adsense.blogspot.com/2008/05/introducing-third-party-ads-on-google.html
