A product feed is the file that holds all the details about your products, like titles, prices, images, availability, and more. It is what platforms like Google, Meta, and TikTok use to pull the right information into your ads.
You can think of it as a specific type of feed built just for ecommerce. While a general feed might include all kinds of data, a product feed is focused on your catalogue and is the backbone of campaigns like Google Shopping or Meta Dynamic Product Ads. Keeping it accurate and well-structured means your ads show the right products, with the right details, at the right time.
