I have 2 autoblogs, one is 500-700 visitors daily with over 2000 impressions and one is 160-250 visitors with around 400 impressions. 90% of traffic is organic (google, bing, yahoo). I make $2-$5 with adsense but I think I'm missing some bucks. I made 10 sales at amazon this month ($8 commision). I tried popup too, but sucks. Any other idea? Thank you If you have questions please don't hesitate.
