Lets share our general strategies if you're goal is to make money from Adsense... Mine is pretty much, get some niches, throw out some optimized pages, get back links.
And don't forget that making money off of AdWords means that visitors not only have to visit your pages, but they have to click on the ads. Try removing ad borders, matching ads to the formatting of your page, incorporating ads into your content and other tactics to improve CTR. Experiment a little to see what works best for your page. An increase on click through rate of only a small percentage can create large increases in revenue depending on your traffic levels.
