I have a question about Google's Adsense policies regarding image ads that I've been trying to find an answer to and I was hoping someone here may be able to shed some light on it.
Essentially I'm trying to determine if it is in violation of Adsense's placement policy to have a Google image ad on the same page as an image ad from a third party advertiser or network. Google's policy states:
You're welcome to display Google ads on the same site or page as other third party advertisements provided that the formatting or colors of the third party ads is different enough from that of the Google ads. In other words, if you choose to place non-Google ads on the same site or page as Google ads, it should always be clear to the user that the ads are served by different advertising networks and that the non-Google ads have no association with Google. If the formats are naturally similar, we ask that you choose different colour schemes for the competing ads.
This makes sense when dealing with competing contextual ad placements, but what about competing image ad placements ? Changing the text or background color to differentiate the placements wouldn't be applicable - image ads have no customizable design elements and there's nothing to tell what advertising network any given ad is being served from.
On that basis, is it permissible to have, for example, a 300x250 Google Adsense image placement and a 728x90 third party ad image placement on the same page ?
What about a 300x250 Adsense image ad on one page and a 300x250 third party image ad in the same location but on a different page on the same site ?
