I've only been at this for 3-4 months, so my stats aren't going to be as accurate as some of you who have done this much longer. Have you guys noticed a significant drop in CPC on the last day of the month? Is that normal? Are people setting a budget per month? Any feedback would be appreciated.
I have noticed lately that the CPC fluctuates according to traffic. I was on the front page of digg today and i was getting more per click than i have ever got. Appart from that seems pretty normal.
