Meta recommends running only one catalog (preferably full-shop) to preserve learnings and optimize ad performance.
See why Meta recommends a single catalog.
If you want to group certain products together, Meta allows you to create product sets within the Commerce Manager. This helps you create more targeted ads with specific sets of products, without having to create multiple catalogs.
You can also use intro cards to set context for the products set in your ads.
PS: If you want to apply category-specific or product-set-specific designs in your catalog, reach out to us and we’ll set them up for you.
