**What is google_product_category, in plain terms?**
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.
**How often should this be checked?**
Regularly, not just once. Copying a competitor's category assignment without verifying it's actually correct for your specific product attributes. Set a recurring reminder rather than trusting memory.
**What's the most common mistake here?**
Defaulting every product to a generic top-level category out of uncertainty, which weakens matching for the entire catalog.
**Does this actually affect rankings, or is it just best practice?**
It's rarely a single ranking factor on its own, but it affects whether search engines and users can do what you actually need them to do — which shows up in rankings indirectly, often more than any one direct factor would.
**What's the fastest way to check this on an existing site?**
Google Product Category Finder — paste your URL in and it does the check directly, no setup.
