This article is a collection of some useful material on Adsense in general. The more you know about the program, the more effectively you can use it on your web site. Start with an overview of the Adsense program, from Google themselves. Then read the Wired article on Google Adsense, as well as the article on Sitepoint. It is a bit dated, but still a good Introduction to Google Adsense. USA Today also has an article on Google Adsense. Then read Google's Adsense Optimization tips are very practical and helpful. A whole subindustry has been spawned by Google's Adsense, such as a web site called TopPayingKeywords.com. ProBlogger is a blog by Darren Rowse of Australia, on making money from blogging. In February 2005, he was asked whether Google Adsense is making him rich. By September 2005, he said that he is making six figures annually from Adsense as well as other affiliate programs (e.g. Chitika). In another post, he said that Chitika earns him $700 per day, while Google Adsense earned him $15,800 in August. Rowse is not the only one writing about Adsense. For example, you have Eric Giguere, who runs a blog on Adsense, and also wrote a book on Adsense. He happens to live in the same area that I live in.Like any piece of software, Google Adsense is not perfect, here is what do do when Google serves the wrong Ads. Criticism of Google's "dont talk about Adsense" policy has been voiced, for example, at kottke.org. Anywhere there is money, there is bound to be abuse by some. For example, read about Search Engine Optimization (SEO) and how it is abused by some "consultants".
