Supplemental Feeds Explained

Demo content: review and edit before promoting this page.

A supplemental feed adds or overrides data in your main feed using a simple Google Sheet. It is the fastest way to improve a feed and a tool I use in almost every Merchant Center project.

What you can change

• Titles and descriptions
• Custom labels for margin and best sellers
• Product types and categories
• Missing attributes like color or material

How to set one up

Create a sheet with the product ID and the columns you want to change, then add it as a supplemental source in Merchant Center.
