Here is my latest message from AdSense -
<edit> saying at least 50% of pages are opted out of image ads and advising that opted in earn more revenues</edit>
Uh, that would be 100% of the pages on my site.
(Notice the typo - "opt-in to text ads" s/b "opt-in to image ads")
The problem is, I don't believe this.
I believe that ALL image ads are CPM, and do NOT pay as well as text ads. They cannot possibly compete with the eCPM of over $10 for CPC ads. From reading this forum, I have concluded that, if opted in, low-paying image ads get "jammed in", in spite of not paying as much. There is NO "pure-auction". I believe that many threads have proven this.
