I have been working on the site below maybe not as much as I want to but I do have adsense all over the place and when I check my site I never see any ads. They are for the most part blank. I see the ads on my other sites that I own but not this one. I am not sure if it's the content and keywords that is causing the problem. If so I am not sure what else to do with it. Any ideas or suggestions? Thanks! http://www.publicwrongness.com/
There are 2 possibilities to your problem: 1. Either there are no advertisements available for the content you have on your website. 2. Google Adsense is unable to read the material on your website and therefore it is unable to generate ads. For this case, you need to optimize your theme.
Sometimes your site does not have relevant content and the adsense does not have suitable ads for it...
