Im helping a friend with his 2 sites with same amount of trafific and we have a top banner space that i'sent used but will there be any CPM that will pay off?
the stats for each sites is
1000 Visits a day
500 unique visits a day
5000 pageviews a day
for now we have google adsense other places on the site that is giving arround 15$ a day from each site but we like to get more..
