Blogger, which you can set up for free in less than five minutes, automates Google AdSense so that you can make money with your blog by displaying ads and getting paid when people click on the ads. To make more money, set up an affiliate program (see below) for books, music, and more, and insert your affiliate links whenever you refer to those items. A good strategy to set you on the path to success is selecting a unique topic, writing intelligent copy, and telling all your friends. You'll be off to a better start with a targeted audience.
