# Structured Data for E-commerce and AI Search

Treat product, offer, shipping, and return markup as a governed commerce-data contract. It can support eligibility and understanding, but it never guarantees a rich result, ranking, or AI citation.

Structured data is machine-readable information that helps search systems interpret eligible pages. For ecommerce, the durable work is aligning visible product data, JSON-LD, feeds, policy pages, and operational source systems. Google explicitly states that its AI features have no extra technical requirements or special schema type, and inclusion is not guaranteed.

## Outcome

Establish a release-tested schema program for Product, Offer, variants, shipping, returns, and organisation data that remains accurate when price, availability, policy, or rendering changes.

## Model the product and commercial offer separately

Use `Product` for the item and `Offer` for its purchasable state: price, currency, availability, condition, and canonical offer URL. Where variants have distinct commercial attributes, model the group and variant-specific products truthfully rather than emitting one misleading price or availability.

**The commerce data contract**

1. Commerce source — Price, availability, identifiers, shipping, returns, and variant state are maintained.
2. Rendered product page — A shopper sees the same material information used in markup.
3. JSON-LD and feed — Structured representations are generated from the approved contract.
4. Validation — Rendered output, Search Console, and data-quality checks expose drift.

*One governed source should drive the product page, JSON-LD, feed, policy content, and monitoring checks.*

## Publish policy data at the right level

Use organisation-level return and shipping policy markup for the standard merchant policy. Use offer-level markup only for genuine product-specific exceptions. Keep countries, fees, methods, delivery windows, and seasonal changes aligned with visible policy and Merchant Center data; Google documents a precedence order when these sources disagree.

| Data | Preferred scope | Release owner |
| --- | --- | --- |
| Product identity and variants | Product page | Commerce/catalogue team |
| Price and availability | Offer | Pricing and inventory system |
| Standard shipping and returns | Organisation policy | Operations and legal review |
| Product exception | Offer | Product and fulfilment owner |

**Representative release check**

```
product=SKU-101
visible_price=129.00 EUR  jsonld_price=129.00 EUR  status=match
visible_availability=in_stock  jsonld_availability=in_stock  status=match
return_policy=EU-30-day  policy_source=approved  status=match
rendered_jsonld=present  rich-results-test=valid
```

## Validate rendered output, not application intent

Google supports JSON-LD and recommends it because it is easier to maintain at scale. JavaScript may inject it, but Google processes crawling and rendering separately. Validate representative rendered HTML in Rich Results Test and URL Inspection, confirm a `200` indexable canonical URL, and ensure critical data is not hidden behind session, geolocation, consent, or blocked API calls.

Use content-fingerprinted JavaScript assets. Googlebot may use cached resources, so a changed asset should receive a changed URL rather than relying on cache-control alone. Do not use FAQPage as a new ecommerce-rich-result tactic: Google's FAQ rich-result feature was deprecated in 2026.

## Measure eligibility without promising AI visibility

Monitor Merchant Listings and structured-data reports, errors, manual actions, feed parity, and affected landing pages. Use before-and-after analysis with a documented release date. Say that accurate visible structured data can support eligible merchant and rich-result experiences; do not say it guarantees AI Overviews, AI Mode links, rankings, citations, or sales.

## Structured-data failure modes

- JSON-LD price, availability, shipping, or return policy disagrees with visible content.
  - Variant markup collapses distinct offers into one incomplete product.
  - Client rendering leaves crawlers without the fields present in a browser session.
  - A team adds hidden, stale, or review markup that is not representative of the page.
