I think it's a common problem for new publisher. Ask them who makes $100 daily or more. Have they ever feel tired like you? Many people tired of cents by cents. But the choice is yours. You want to stop here or trying harder to raise your income like people have done before?
Are you kidding me??? Why are you displaying adsense on that niche site? Get some business card affiliates they pay out very nicely. Sometimes adsense is just garbage. Also, by limiting it the NUMBER of adsense blocks (2 instead of 3, 1 instead of 2) I've noticed payouts rise. So use less adsense ( or none) and add a few affiliate programs.
You have had already had some very good suggestions above from other members so take note of them For me adsense is not an income stream priority and there are many other ways to make money online........ Its so hit and miss with so many webmasters getting too obssessed with adsense they foget about other opportunities. I see it as a nice extra bonus from a site to help recover expenses but i realised a long time very long time ago that few would make enough from adsense to live off If you really want to make more with adsense just read, read more and learn from the free advice from such places like here at DP - if you try different things then stick with it and dont give too so soon. Its a hard road, toil and struggle for a lot of us too
The key is getting more traffic. Focus on building quality search engine traffic to your site, and you'll see an increase in the income.
