what is your source of traffic which give you money thru Adsense. If you have multiple source then plz specify in %. First i do. 1% from Link Exchange 10% Adwords 88% from other websites related to my website ** and i m getting $0 from Adsense. I don't know which traffic will give me some relief.
I don't think that there's such effective corelation between the SOURCE of traffic and ad revenue. The AMOUNT of traffic(in unique visitors) and far more important than that, ad marketing technics will bring you the bucks. I had several thousands of unique visitors each day, but I used to earn less than a dollar/day. Then I analyzed the traffic, popular pages and visitor behaviour. Found the best placement that fits my site. Now I make two digit numbers each day.
More than 50% of my traffic comes from Google search (I get a fraction of the traffic from other search engines). That's primarily because I've spent a great deal of time working on SEOing my site. Another 25% of my traffic comes from regulars. These are people that have bookmarked my site or subscribed to my RSS feeds. Hope this helps,
