What does this check that the feed check does not?

The public product list on a store hides GTIN, google_product_category, condition and identifier_exists. A feed file has them, so this is the only way to validate the fields that most disapprovals come from.

Is my feed uploaded anywhere?

The file is read in your browser and only the text is sent for validation. It is not stored and not shared. For a feed with sensitive data, paste only a sample of rows.

Google Merchant Center CSV and TSV exports, and RSS 2.0 or Atom XML feeds. The header row names are matched case-insensitively.

Titles under 150 characters with no promotional text or all-caps, a description, a price above zero, availability, an image link, a brand, and an identifier (GTIN or MPN, or identifier_exists=no). These map to Google’s published product data requirements.

Check the fields Google rejects that a public page hides

Your store’s public product list does not expose GTIN, category, condition or identifier_exists. A Merchant Center feed does. Upload or paste it and check every required field — free, in your browser.

What this checks

Each row against Google’s product data requirements: a title under 150 characters with no promotional text or all-caps, a description, a price above zero, availability, an image link, a brand, a link, and an identifier (GTIN or MPN, or identifier_exists=no), plus a google_product_category and a valid condition. These are the fields most disapprovals come from and the ones a public catalogue scan cannot see.
