What I can tell you from my own experience is this:
1. Ads at the top of the page and on the left of the page perfom better than any other ads. (Take a look at the "heatmap" from the Google link below)2. Ads without background colour and borders perfom better than ads within borders with background colour.3. Ads within content pages perform better than any other ads.4. A search box on every page gives you another chance for earning Adsense income.5. Your link at the top of the ad should be blue like a normal link, the ad should be black, and the url should also be black so that it blends in with the ad copy. That makes the link stand out and gives you a better chance of someone clicking on it.

Another way would be to publish articles by other authors that are relevant to your site content. You can find free articles all over the web by once again doing a search for e.g. "free site content".
