I'm getting a bit nervous, for some of my sites the eCPM , mainly the CPC is going way down in the last few days, from 10-20 cents to 4-6 cents... eCPM from 5-8 $ to 1 $... Traffic is about same (2000 uniques/day), CTR about same, what is going on ? The sites in questions are a mobile portal and a cars gallery... Help appreciated
If your site is a leader in its catagory, and doesn't make Google think "They are in this all for the money" then you get smart priced in a GOOD way. It works both ways.
