Although the glass ceiling is a mythical being, I believe in it. I have the following observations to support this idea:

- On days that site 1 performs well eCPM-wise, site 2 performs poorly and vice versa.

- On days with high CTR, eCPM tends to be low.

And more of these obvious anticorrelations.

Ofcourse you might also interpret this as being a glass floor, but whatever it is, I want to break free. Google seems to think you're wrth X, so you're getting X every day, whatever it takes. It could ofcourse be some statistical effect, but I've been noticing above effects for a while now. Anybody have any experience with the mythical glass ceiling? If so, did you break free, and how?
