I've had 41 + page impressions today and not a single ad click. I've had probably over 100 page impressions since I've started my site a few weeks ago and not a single click. In the past, I've gotten clicks with less impressions. Was that luck? Does it actually require more traffic to generate one click?
Depends strongly on the type of site... For me every 700th page impression was a click. Not sure how that compares to others EDIT: Every 70th, not 700th
sometimes its 1500+ page impresions single click and sometimes 10 page impresions and 3 clicks all on luck!!!
