Deduplicate a product catalog in three passes: match on GTIN or manufacturer plus normalized MPN, fuzzy-match the rest, then human-review the ambiguous band.

GTINs, UPCs, MPNs, and the identifier hygiene that decides whether your products are matchable anywhere.

Deduplicate a product catalog in three passes: match on GTIN or manufacturer plus normalized MPN, fuzzy-match the rest, then human-review the ambiguous band.

Agents read fields, not pages. What a distributor or manufacturer catalog actually needs — MPN-first identity, UNSPSC/ETIM classification, spec attributes, UOM and pack hierarchies — and how to get it into schema and feeds.

In industrial distribution, most SKUs will never have a GTIN. Brand plus manufacturer part number is the key that actually resolves — and supersession is what breaks it.

How GTIN, MPN, and brand in Product structured data drive Google and AI product matching, plus how to implement and validate them correctly.

Why a wrong or reused GTIN quietly delists you from Google, marketplaces, and AI answer engines, and the fixes that actually hold at scale.
