I know google doesn't like users talking about CPM, so please don't post any numbers in this thread... Does anyone know if the eCPM is usually higher for "image only", "text only", or "mixed"? I would test it, but mine is always around 0 no matter what, haha...
Yes, it depends on what the advertisers are spending for the text and image ad formats. Text ads will probably pay more as there is more advertisers bidding for the different keywords for the text ads as they are much more easily to create than image ads.
