02 / A DELIBERATELY LIMITED PROFILE
File checks.
Honest boundaries.
This checks a subset of Google's requirements for English-language US/USD feeds of new branded ordinary physical goods. Google can still reject a file or item. We have not performed a live Merchant Center upload test.
Rules reviewed October 20, 2026. Google product data specification ↗ · File formats ↗
Checked locally
Required pilot fields, record widths, unique IDs (including case collisions), selected text lengths, positive USD price syntax, new condition, in_stock/out_of_stock, HTTP(S) URL syntax, GTIN digits/length/checksum and identifier-field consistency.
Formatting changes only
Known header case/whitespace, supported availability/condition capitalization, explicit USD formatting and blank records. IDs, GTINs, MPNs, titles, descriptions and price amounts are not guessed or rewritten. Missing data stays missing.
Not verified
Live pages/images, image dimensions, crawlability, product authenticity, GS1 assignment/prefix rules, site price/stock matches, shipping/tax/returns, policy compliance, AI-asset disclosures, special category requirements, approval or Shopping performance.
Outside this pilot
Apparel, variants, bundles, custom/unbranded goods, used goods, special categories, preorders/backorders, sale prices, XML/API, account appeals, automatic fixes to websites or Merchant Center, and arbitrary column mapping. Other valid Google attributes also need a broader workflow.
Exact supported headers
id, title, description, link, image_link, availability, price, condition, brand, gtin, mpn, identifier_exists. All except the last three are required by this pilot. Supply an authentic GTIN or manufacturer MPN; MPN is only appropriate where no manufacturer GTIN exists. We never invent identifiers or set identifier_exists=no to hide missing data.
