Use a contextual ad service. Once your blog contains high quality content and has begun to attract an audience, you can make money using Google Adsense, WordAds, or any other contextual ad service.

Once you setup your account on AdSense you will be given a code to add to your blog. This code will automatically display advertisements on your blog from companies who are part of Google’s advertising network. You may see ads from small companies related to your topic, or you may see ads from large companies that are completely unrelated to your topic.
