Google Product Category Finder

This tool searches Google's own product taxonomy file for categories that share words with your product, hands the model that shortlist as candidates, and tells it to pick only from those candidates or from the top-level categories. It never lets the model invent a category ID or path, which is the failure mode of asking a general AI tool to "guess" a Google category.

It picks the most specific category that's really true for the product, matching what the product is rather than its material, audience or occasion (gold earrings are "Earrings", not a metal category), and ignores a shared word that means something else, such as a "hoop" earring versus a basketball hoop.

Google assigns every product a category automatically from your title, description, price, brand and GTIN. Setting google_product_category yourself matters mainly when Google gets it wrong, when you want to organize Shopping campaigns by category, or for alcoholic beverages, where Google requires the correct category for compliance.

1. 01

   Shopify

   Set each product's Category on the product page in your admin, using Shopify's own taxonomy. If you paste in the exact English Google category path or ID, Shopify maps it to its own matching category.

2. 02

   WooCommerce

   WooCommerce has no Google category field of its own. Paste the ID into your feed plugin's Google product category setting, or add a google_product_category column to your feed.

3. 03

   Merchant Center feed

   Add a google_product_category column and give each product either the ID or the full path, never both.

Double-check any match against Google's own taxonomy file before you publish a feed.
