My site is isawyoustjohns.com and it's basically a missed connection website. I don't write articles or anything. It's the users who post their sightings about missed connection. I'm not sure how to improve keywords here. 18 clicks and $1.07. Is it too low? or the ads aren't much high-paying I'm getting that notice because I have to verify the PIN which I'm waiting for Google to mail me the postcard.
That CTR is REALLY low.. I guarantee you that if you can put an ad-block in the top-center area, like before the first post, you can at least double your CTR and earnings.
Why would anyone come to your site to click on adsense ads? Do any of the ads have anything at all to do with your subject matter. Matching user intentions to ad content is the key to getting clickthrough. If a visitor comes to your site... you need to know why. And you need to offer them ads that match the why. I don't see this as a good fit for high clickthrough.
