<<Earlier this year we simplified the process for monetizing your blog by adding a “Monetize” tab in the Blogger app. We started with AdSense, which allows you to add contextual advertising to your pages; more recently we added AdSense for Feeds to help you generate revenue from the distribution of your blog via RSS and Atom. Today we launched a third option: direct integration with Amazon Associates to search Amazon’s product catalog and add links to products that earn you commissions when your readers buy products you recommend.>>
