In my experience, it’s product-related blogs that tend to do best with Amazon. Most blogs probably have at least some possibilities (for example here on ProBlogger I occasionally link to a book that relates or a computer or electronic tool that I think might be useful to bloggers) but the reality is that this blog will never convert as well on Amazon as my photography site.
Throw a bake sale if you like to cook. Choose classic recipes that are easy to make in big batches like chewy chocolate chip cookies, fudgy brownies, or vanilla cupcakes. Once you bake everything, separate your goodies into individual servings and place them in pretty packages like treat bags tied with ribbons. Set up a stand in your front yard or out on the street corner to get more traffic.
