Here is a idea that has been bouncing in my head for past several minutes. So I better put it down before I forget . Apologies in advance if this has been mentioned before. I would love it if the output of the coop ads could be more like adsense so coop publishers could use it as an ad alternative for adsense. This would mean that there would need to be a way to output the ad block in a similar format as adsense ad blocks. And for publishers it would a bit more work since the ads would need to be on a separate page to be referred from the adsense code. Personally I would love it if my ads were in the top fold of web page rather than at the bottom depths of a page.
I don't see why you couldn't run them as alternate ads, but I guess it would just depend on the AdSense ad size you were using.
Yes you are right we could right now. But to make the look the same as adsense ads would be harder I think - most struggle with basic formatting. So automating it would be great and it would encourage people to use it as alternative ads. And this would get ads above the fold and get more clickthroughs for advertisers.
