The question are relevant for me beacause each time I put a new web page - it gets great ECPM but after few weeks it is decreasing (without any change in the CTR)
Do you know about other parameters that affect the ECPM when the CTR does not change?
OR it could just be changes in visitor behavior. Do you have a lot of regulars? Do you announce new pages? Maybe visitors act differently on new pages than on ones that have been around a while--same CTR, clicking different ads.
Are your new pages about distinctly new topics not covered elsewhere on your site? Do they overlap a little? Or are they more of the same?
You said "suddenly the eCPM slowly decrease." Which is it? A sudden decrease or a slow one?
We can only speculate without knowing much more about your niche, though.
Some Questions :
What is the smart pricing? When does google says that the site is not converting well?
What do you mean in "breach of TOS on any of the site pages"?
What is the "competitive ad filter to best effectivness"?
