Google has launched the "direct integration with Amazon" feature on Blogger.com.
This feature allows you to search the Amazon product catalog directly from the editor of Blogger.com and add images / links to Amazon products right in your posts. You earn commissions when your readers buy the products from your post.
This is known as an "affiliate program" and is designed to earn you a commission, if anyone buys the product through your link.
To begin, click on the "Monetize" tab on your blog dashboard and click on "Amazon Associates". Walk through the wizard. If you already have an Amazon Associate account, completion of this setup is simply by adding your Amazon Associates ID, but if you do not have an Amazon account, you can register free without leaving Blogger.com.
When you write a post on Blogger.com, you'll see an Amazon widget on the right of your editor. You can search the Amazon product catalog in Blogger.com - type the name of the product and add it on your post.
Each link is created containing your unique Amazon Associates ID to ensure Amazon credit all the purchases resulting from your links.
