I have 3 ad units on most pages.
1: 728x90, very top of page, above everything, image only
2: 160x90, AdLinks in the left column under the 1st paragraph.
3: 300x250 or 336x280, text and image, center column under the first photograph.
(The right column is all inhouse internal links.)
In the past this has worked well. But after seeing this thread I went investigating my earnings and it looks like a little experimentation might be in order.
I'm most curious if changing the 728x90 to text only or text and image would make a positive difference.
The AdLinks is what it is, nothing to do there.
The center adblock, I dunno, we'll try messing around with it and see what happens. Recently it looks like text ads get about 1/3 the impressions but earn twice as much as the image/etc ads in that spot.
I've mostly thought allowing both image and text would get the highest payout, which has been true on my sight in the past.
Not sure now.
