I just checked my earnings back for my best earning month, October of 2007.
I had 7300 clicks, with an average click value of 14 cents. Since then, it has unfortunately dropped to my previous number of 9 cents per click that I posted earlier, and I only get around half the clicks that I did at that time.
Also, so far for January, my average click value is only 5 cents.
Why the heck does it keep going down like this? I know the first day that I started my biggest earning site, the very first click was worth $2. I would do anything for that earning again.
