hi i have over 17 site and have adsense on all those still cant earn even $1 per day the funny thing is i have adbrite on just 3 site and make $3 to $5 thanks in advance for any help
Try to add different add placements and blend their color .Can you share stats of traffic on your sites and links so we can check them further .
Most of the time it depends on the niche you are in. Don’t compare between adsense and adbrite because sometimes each will works well on different niche. Have you consider doing simple things like checking whether the served ads are relevant, working on the ad placement and blending. All these help towards the CTR
CTR is something I struggle with as well, but then again, I have very low traffic at the moment, so I feel I need to first concentrate on increasing my traffic, as I am only getting about 160 page impressions per month right now. Then I will worry about my CTR. This may be the case with you as well. How much traffic are you getting?
I agree with dgarman. CTR is a variable factor and it is dependent on many things. How well you have optimized ad placements in every way, and whats your niche.
