Free tools for your Shopify catalog

One question, one answer, no signup
Google Merchant Center and AI shopping agents like ChatGPT skip products whose data they can't read: a blocked crawler, structured data that disagrees with the store, a barcode with a wrong check digit, a promotional title. Each tool here tests one of those, using the same rules as the catalog audit.
Every check on the checks page says which tool tests it. Need a hand fixing what you find? Talk to us.
