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?
What was your overall earning (what really matters) doing? Mine has gone steadily up from Day 1 (with the obvious inter-day fluctuations so common to Adsense) Actual earnings are what they would curb, not the CTR, nor the eCPM, but what your bottom line is. Since there are people who can make 4-figures per day, if there IS a cap, I'd say most people are a long way from reaching it. And I doubt there is one.
