## FAQs

### What is a product catalog?

A product catalog is a structured collection of all the products a business sells, with their attributes (titles, descriptions, prices, images, availability, identifiers), organized for use across ad platforms, shopping channels, and storefronts. On platforms like Meta, the catalog is the central product database that powers shops, dynamic ads, and collection ads. It's the organized source of truth for what you sell and its details.

### How does a product catalog relate to a product feed?

They're closely linked: the product feed is typically how data gets into and updates the catalog. The feed is the structured file/connection delivering product data; the catalog is the organized product database the platform maintains from it. You supply or connect a feed, and the platform builds and refreshes the catalog used by your shopping and dynamic campaigns. Feed quality determines catalog quality.

### What powers shopping and dynamic ads from a catalog?

The catalog provides the live product data — images, prices, availability, links — that platforms use to automatically generate shopping ads, dynamic product ads, and collection ads, and to retarget users with the specific items they viewed. Instead of building ads product by product, the catalog lets the platform assemble and personalize product ads at scale and keep them accurate as inventory changes.

### How is a product catalog organized?

Beyond individual products, catalogs use structure like product sets/groups (subsets defined by rules — e.g. a category, a sale collection, or best-sellers) that let you target ads to specific portions of the catalog. Proper categorization, variants (size, color), and attributes make products discoverable and matchable. Good catalog organization enables precise targeting (advertising specific sets to specific audiences) and cleaner dynamic campaigns.

### Why is catalog management important for e-commerce ads?

Because the catalog is the foundation of all catalog-driven advertising — its accuracy and completeness directly affect ad eligibility, matching, personalization, and performance. Poorly managed catalogs (missing data, errors, stale stock) cause disapprovals, mismatched or wasteful ads, and bad customer experience. Investing in clean, well-structured, up-to-date catalog data is one of the highest-leverage things an e-commerce advertiser can do.
