Two Formats, Two Strengths
In Meta's ad ecosystem these two formats work hand in hand but serve different needs. Catalog Ads (sometimes called Dynamic Ads) connect your entire product inventory to a data feed, and Meta's AI automatically decides which product to show to whom and when. Collection Ads present a curated group of products as a visual storefront; when someone taps the ad, a full-screen instant storefront opens right inside Facebook or Instagram — no browser redirect needed.
How Does a Catalog Ad Work?
You start by creating a product catalog that holds your items' key details — price, stock status, image, and title. This catalog becomes your product database on Meta. Once the campaign runs, the system automatically rotates the most relevant products to each user, whether they visited your site before or simply share similar interests. With 500 different products, you don't need 500 separate ads; one campaign covers the whole catalog in a personalised way.
- Catalog Ad: Your entire product list connects to one campaign; Meta's AI decides what to show to whom
- Collection Ad: A large cover image or video on top, four product cards below; tapping opens a full-screen instant storefront
- Advantage+ Shopping Campaigns (Meta's AI-powered shopping system): Combines catalog targeting with automated audience optimisation
- Retargeting: Users who visited your site without buying can automatically see the exact products they viewed
- Prospecting: You can also reach new audiences who share similar interests to your existing customers
According to Meta, the majority of shopping journeys begin on mobile devices — the full-screen Collection storefront is designed specifically around this behaviour.
