Long-form writing on product data, structured markup, identifiers, and how AI shopping agents use your catalog — not algorithm chum, practical signal for merchants.
▷ Get a free scanllms.txt and agents.txt are in the news, but they sit on top of product truth: identifiers, schema, and feeds. Here is how discovery files, structured data, and commerce protocols fit together without turning into buzzword soup.
Identifiers are how agents dedupe products across retailers and marketplaces. A missing barcode is not a paperwork issue — it is a visibility issue in agentic commerce.
Large language models can parse HTML, but they are far more reliable when product facts are machine-readable. Schema.org markup is still the clearest contract between your store and an agent.
Search optimisation still matters, but AI shopping agents do not page through SERPs. They synthesise answers from structured product data. Here is what that means for your catalog.
Guides, MCP setup, and the changelog sit under Resources — same editorial standard.
