I was allowing G text ads only and yesterday turned on text_image ads to give a try to the new site targeting feature. My eCPM went down significantly today. It could be a coincidence, not sure... In any case, I switched back to text only ads. Has anyone else experienced this?
nofsar, That's good to know. Thanks. So, is my understanding correct: you have to have image ads enabled to take advantage of the new features (including site targeted ads)?
The email was a bit vague, but yes probably. However, those ad features have not been implemeted for everyone yet, so I wouldn't worry about it until we hear more from google on it. Stick with what pays better for now
