I setup my AdSense account about a week ago. The first full day we made about $50 on 100 clicks (hypothetically speaking). Our traffic received a major boost in the past few days and our impressions and clicks have increased significantly, although the earnings have stayed constant. Today we had 200 clicks (exactly double the first day) and our commission was less than $50.
I have added a few competitor sites each day to our URL filter and I am wondering if this is to blame for the earnings flatline. They are bigger sites who are probably the top bidders in their keyword categories.
Any thoughts, or I am missing something fundamental about how this systems works.
