Product / Offer schema

Why an agent cares

It is the only machine-readable statement of what a product costs and whether it is in stock, so a wrong currency or an unrecognised availability value makes an agent quote something false. Several of these are Google profile requirements rather than schema.org requirements, and the reference says which.

Adoption

Web baseline. Standard equipment on the web. Its absence is the exception rather than its presence.

Direction of travel: ► flat, as at 2026-07-28.

Mature and measured: 0.77% of pages via JSON-LD and 1.50% via microdata (Web Almanac 2024), concentrated on product pages. Note that OpenAI chose a product feed spec over crawled markup.

What we check

Examples

Both of these are fixtures the test suite runs through the real collector, not snippets written for a document: the first is a shape we score as valid, the second is one we flag.
