I managed to enlarge my site traffic from 300 to 1000 pages/day, and my clicks number growed correspondingly. But somehow I have a feeling that I started to get less for each click. Significantly less. Do you think there is any connection ? I also enlarged te number of pages about the same amount.
Same thing over here, more targeted traffic leads to a huge drop in epc. I don't believe this is how smart pricing is supposed to work but it seems like whenever you have a surge in traffic, it's going to think they're junk traffic. I am starting new sites and making sure they don't get too big to try to win over sp.
I have sites with 50 pages and sites with 20K+ pages, both average about $0.25 per click. So I don't think it has anything to do with size of site.
