You have 11 sponsors that you made 0.02$ per click through or LESS.
Get rid of them for a start. And use those other sponsors instead, or find new.
Why bother with those loosey sponsors?? One of them you have 40 sales. Then 10, 14,6,4,4,4 -- those are the ones that deserve more traffic. If you have to, depending on if they are niche based or not you can just sell your terrible blogs, and invest more time in to the ones with the majority of sales/profits.
Hope this could help you out some.
