If you've never touched google_product_category before, here's the version without the jargon.
Getting `google_product_category` wrong doesn't usually cause outright rejection — it just quietly routes your product into the wrong Shopping surface, competing against irrelevant listings instead of the right ones.
You don't need to understand everything about it on day one. Start with just this: pick the most specific applicable category, not the broadest parent — 'Apparel & Accessories > Shoes > Athletic Shoes' beats just 'Apparel & Accessories' for matching relevance.
The most common beginner mistake is skipping it entirely because it sounds technical. It usually isn't — google_product_category is one of those things that looks intimidating from the outside and takes ten minutes once you actually sit down with it.
Once this feels comfortable, competitor product analysis is a natural next thing to learn.
