How Google Affiliate Ads Works
The Google Affiliate Ads program is like AdSense but you are able to chose your affiliate ads based on your blog or post content and earn commission on sale.
How to get started with Google Affiliate Ads
In order to begin your Google Affiliate program, navigate to the "Earnings" tab on Blogger, and click on “Get Started”. In case you have a current Google AdSense account and the content on your blog or website matches available advertisement categories, you're already set up.
