A primary product feed or product catalog is used to power your dynamic ads. It includes basic information like product title, image, price, variations, etc.
A supplementary feed is used to add additional information to your product catalog without losing learnings. If you are currently using a catalog for your Meta ads, we recommend adding a supplementary feed to this catalog instead of creating a new catalog.
Socioh’s supplementary feed is used to update your product images. It will neither add nor remove products from your existing feed.
