Identifiers and categories: GTIN, brand, Google category, product type and variants

This lesson is free — you only need your account

What each identifier does for your visibility (and what you lose with no GTIN), when to declare that a product has no code, how to choose the Google category and build your own product type, and how to group variants so Google shows the right size and colour.
