What Is a Product Feed? Definition, Fields and How It's Used in Ads
A product feed is a structured file or data source that lists every product you sell along with its attributes, such as ID, title, price, availability, image and link, so that advertising and shopping platforms can display and update them automatically.
Each row in a feed is one item, usually one variant (see what-is-a-skew-in-ecommerce), and each column is an attribute. Typical fields include a unique ID, title, description, price, currency, availability, product URL, image URL, brand, and category. Platforms add their own requirements: Google Merchant Center, Meta catalogs and marketplaces each specify required fields and accepted formats, commonly CSV, XML or a direct connection from a store platform such as Shopify. [NEEDS VERIFICATION: confirm exact required fields per platform before publishing a field list.]
Feeds can be generated by your e-commerce platform, by an app, or built by hand in a spreadsheet. They are refreshed on a schedule or in near-real time so that price and stock changes carry over. Because platforms validate feeds, common failures are missing required attributes, images that do not meet size or content rules, prices that do not match the landing page, and out-of-stock items still being advertised. Disapproved items simply do not show, so feed quality affects delivery directly.
A feed powers several ad formats: shopping listings, catalog ads and dynamic product ads (see what-is-dynamic-product-ads), where one ad template is filled with the right product for each shopper. The quality of titles, images and prices in the feed often matters as much as the ad creative wrapped around it, since in catalog-driven formats the feed is the ad content.
Why it matters
Infinall AI does not build, host, validate or sync product feeds, and it does not manage your catalog in Google Merchant Center or Meta. It works from a product URL to produce research, strategy, ad copy and creative, which land in an Approval Queue for you to edit and approve before export. The two sit side by side: your feed supplies the product data that catalog ads show, while Infinall can help draft the surrounding creative, copy angles and brand-level assets you might use in a template. You still set up and maintain the feed itself in your store or ad platform. If you sell a handful of products or run a single hero offer, you may not need a feed at all, and a reviewed set of image ads and carousels can be enough.

Frequently asked questions
What is in a product feed?
A feed is a table with one row per product or variant and a column for each attribute. Common attributes are ID, title, description, price, availability, product link, image link, brand and category. Each ad platform adds its own required and optional fields, so check the platform's current specification before building one.
Do I need a product feed to advertise?
Not always. Catalog-driven formats such as shopping listings and dynamic product ads need one, but standard image or video ads do not. If you sell a small number of products, creating individual ads can be simpler than maintaining a feed.
