Google product taxonomy FAQs

What is the Google product taxonomy?

A fixed list of thousands of product categories Google uses to understand what you sell. Each category has a full path and a numeric ID.

Is google_product_category required?

Google can assign a category automatically, so it is usually optional. Setting it yourself helps when Google guesses wrong, and some categories need it for the right rules to apply.

Should I use the ID or the full path?

Both work. The numeric ID is safer because it does not depend on language or spelling.

What is the difference from product_type?

google_product_category uses Google's fixed list. product_type is your own free-text structure, often your Shopify collections, and is handy for splitting campaigns in Google Ads.

Can a product have more than one Google category?

No. Each product gets one google_product_category. You can send several product_type values.

Does Shopify set this for me?

Shopify has its own product category field based on its own taxonomy. Google's Shopify app maps it across, but the match is not always the most specific one, so it is worth checking.
