Structured Data Reference Chart

Every type below was checked directly against Google Search Central’s own documentation on 2026-09-13 (see the source link on each row) — not recalled from memory, which would be stale for rules that change this often. These rules change — check the source link before relying on anything here for something that matters.

No longer produce a rich result in Google Search: FAQPage and HowTo. Details below.

Article(also: NewsArticle, BlogPosting)

Eligible

No properties are strictly required, but Google recommends these to show author, date, and image details in search results and to support features like Top Stories.

Required

None.

Recommended

  • headline
  • author
  • author.name
  • author.url
  • datePublished
  • dateModified
  • image

Product

Eligible

Google requires at least one of review, aggregateRating, or offers alongside name — and if you include offers, a price is required inside it. Merchant listing (shopping) eligibility mainly needs a few extra Offer details (a real price, priceCurrency, and using Offer rather than AggregateOffer) — it does not require a separate Merchant Center feed.

Required

  • name
  • at least one of: review, aggregateRating, offers

Recommended

  • aggregateRating
  • offers
  • offers.priceCurrency
  • review

LocalBusiness

Eligible

Only name and address are required, but Google states that more properties (hours, phone, price range) produce a materially higher-quality result. Use the most specific subtype you can (Restaurant, Store, …) rather than bare LocalBusiness. Google documents aggregateRating/review here only for sites that aggregate reviews of OTHER businesses (e.g. a directory) — a business publishing these about itself is ineligible for the star-rating feature, so they're intentionally not recommended above.

Required

  • name
  • address

Recommended

  • telephone
  • openingHoursSpecification
  • priceRange
  • geo
  • url

Event

Restricted eligibility

Google's current guidance requires a physical location — virtual-only events, invitation/membership-only events, and school youth spectator events are not eligible for Event rich results regardless of how complete the markup is.

Required

  • name
  • startDate
  • location
  • location.name
  • location.address

Recommended

  • endDate
  • description
  • image
  • eventStatus
  • offers
  • organizer
  • performer

Review

Restricted eligibility

itemReviewed can be omitted only when this Review is nested inside the markup of the item it reviews — a standalone Review (the common case this tool checks) needs it. Google restricts the star-rating feature specifically for LocalBusiness or Organization pages that control reviews about themselves ("self-serving" reviews); first-party product reviews on a merchant's own page are a normal, supported pattern.

Required

  • author
  • itemReviewed
  • itemReviewed.name
  • reviewRating
  • reviewRating.ratingValue

Recommended

  • datePublished
  • reviewRating.bestRating
  • reviewRating.worstRating

Source: Google Search Central — Review snippet structured data

AggregateRating

Restricted eligibility

Same itemReviewed-nesting exception as Review, and the same LocalBusiness/Organization-scoped self-serving-review restriction — it does not apply to Product ratings on a merchant's own page. Google's own examples nest AggregateRating inside the item it rates rather than publishing it standalone.

Required

  • itemReviewed
  • itemReviewed.name
  • ratingValue
  • at least one of: ratingCount, reviewCount

Recommended

  • bestRating
  • worstRating

Source: Google Search Central — Review snippet structured data

BreadcrumbList

Eligible

Needs at least two ListItems, each with a position and a name. The last item's `item` URL is optional — Google falls back to the page's own URL.

Required

  • itemListElement

Recommended

None documented.

FAQPage — no rich result

Google removed FAQ rich results from Search entirely starting May 7, 2026 (having already restricted them to a small set of authoritative government/health sites before that). This markup is valid schema.org but will not produce a rich result in Google Search.

HowTo — no rich result

Google limited HowTo rich results to desktop in August 2023, then removed them entirely — including desktop — on September 13, 2023. This markup is valid schema.org but will not produce a rich result in Google Search.
