ChatGPT Shopping Feed Checker
Validate the Shopify product feed signals TopMention uses for Shopping readiness — GTIN coverage, vendor, price/availability, and Product schema.
Why this matters
AI shopping recommendations need structured catalog data. On Shopify, /products.json plus PDP Product schema are the fastest signals to audit before a full visibility scan.
How it works
Sample products.json
We fetch up to 20 products and measure barcode (GTIN), vendor, price, and availability coverage.
Product schema
We include the light Product JSON-LD check from a sample PDP.
Readiness rollup
You get ready / needs-work / not-ready with per-check status.
What the report covers
Whether /products.json responds with a product list.
Share of sampled variants with a usable barcode.
Vendor plus price/availability completeness.
FAQ
Is products.json the ChatGPT Shopping feed?
It is Shopify’s public JSON catalog. Merchant Center / OpenAI Shopping feeds may differ, but GTIN, brand, price, and availability quality transfers.
What GTIN threshold is good?
Aim for ≥80% of variants with barcodes. Below 40% usually fails Shopping readiness in our audit.
