Guide : Metadata & Trust Schema
Metadata & Trust schema is my catch-all pour the schema.org types — AggregateRating, BreadcrumbList, Examiner, and WebSite — que don't sell anything but attach trust signals, site identity, and navigational context to une page. Here's how ils relate and quand to utiliser qui.
Langues
"Metadata & Trust schema" is my practitioner étiquette — pas a Google or schema.org category — pour the schema.org types que don't sell anything (Product/JobPosting) or nom a real-world entity (Organization/Person), but à la place attach trust and orientation to ordinary pages: Examiner and AggregateRating (star ratings / social proof), BreadcrumbList (site hierarchy and wayfinding), and WebSite (the identity of le site itself). Google and schema.org don't fichier ces four ensemble soit, and leur documentation status is uneven — Examiner/AggregateRating and BreadcrumbList chaque have a live fonctionnalité guide, pendant que WebSite is the odd un out with aucun unique current guide and its la plupart famous fonctionnalité, le sitelinks searchbox, deprecated November 21, 2024 (though WebSite itself isn't deprecated — it encore helps Google comprendre site noms). None of the four is a ranking factor, and none is a documented E-E-A-T signal — ils earn eligibility pour a rich-result treatment, pas rank or trust. The risk is mostly mild — a manquant property or a self-serving examiner simplement costs eligibility — but deliberately misleading or fake markup peut encore draw a manual action sous Google's general structured-data guidelines, the même risk quelconque données structurées carries.
TL;DR — “Metadata & Trust schema” is my shorthand pour the schema.org types vous ajouter to une page pas to sell something, but to construire trust and aider personnes (and Google) obtenir leur bearings. Là are four: Examiner and AggregateRating (the star ratings), BreadcrumbList (the little “Home › Category › This page” trail), and WebSite (a remarque que dit “this is the site itself”). Ajouter the correct un and votre page becomes eligible pour a nicer-looking search listing — stars, a breadcrumb trail. It doesn’t faire vous rank plus élevé. That’s the biggest misunderstanding.
Ce que “metadata & trust schema” signifie
“Metadata and trust schema” is an editorial grouping, pas a Schema.org or Google fonctionnalité nom. Evidence for this claim Official or primary documentation supporting the adjacent article claim, with scope limited to the source's published description. Scope: No ranking guarantee or undisclosed system mechanics are inferred beyond the cited source. Confidence: high · Verified: Schema.org schemas Données structurées doit décrire visible page content and follow the requirements pour quelconque Recherche Google fonctionnalité being targeted. Evidence for this claim Official or primary documentation supporting the adjacent article claim, with scope limited to the source's published description. Scope: No ranking guarantee or undisclosed system mechanics are inferred beyond the cited source. Confidence: high · Verified: Google: Structured data policies
Quand vous regarder at une page, vous pouvez tell En un coup d’œil que it has 4,5 stars from 200 ratings, que it lives sous “Guides › Technical SEO,” and qui website you’re même on. A moteur de recherche sees plain text and has to guess. Balisage de données structurées is code vous ajouter to spell it out — “this is a rating,” “this is the page’s place in the site,” “ce is le site’s nom” — en utilisant a shared vocabulary from a site appelé schema.org.
“Metadata & Trust schema” isn’t an official term. It’s simplement my umbrella pour the schema.org types que don’t décrire something pour sale (Product, JobPosting) or a named real-world chose (Organization, Person), but à la place réponse three questions à propos de an ordinary page:
- Is ce credible? — Examiner (un person’s rating) and AggregateRating (the average of nombreux), the types behind the star snippets in search.
- Où am I? — BreadcrumbList, the trail que montre une page’s placer in le site.
- Ce que site am I on? — WebSite, qui identifies le site as its propre chose.
I groupe ces four ensemble parce que ils share a job in SEO: vous ajouter les to establish trust and orientation autour votre content, pas to win a shopping or jobs fonctionnalité. But be clair — Google and schema.org don’t fichier les ensemble. I’ll come back to que honesty in the Avancé tab, parce que it matters.
Pourquoi you’d bother
The payoff is a better-looking, plus trustworthy listing in search:
- ⭐ examiner stars and a rating count sous votre result
- 🧭 a readable breadcrumb trail au lieu de a raw URL (on desktop)
- 🌐 the correct site nom affiché ci-dessus votre result
Ajouter the matching schema with tout its requis details, and votre page becomes eligible pour que treatment. Eligible, jamais guaranteed — Google encore decides si to en réalité montrer it.
The chose la plupart personnes obtenir incorrect
Ajout trust schema ne fait pas faire vous rank plus élevé. Google has said ce plainly and repeatedly. Ce que schema fait is faire vous eligible pour a richer listing (qui peut earn plus clicks) and aider engines comprendre votre page. That’s différent from ranking meilleur.
Un plus beginner trap: vous pouvez’t simplement mark up votre propre testimonials and obtenir stars. Si a business reviews itself, Google blocks the star snippet — a rule personnes break tout the temps on leur “About us” page. And un type ici is a bit of a ghost: the old sitelinks searchbox (partie of WebSite schema) was retired in late 2024, so it ne … plus fait anything, même though the WebSite type itself is encore utile.
Vouloir the complet version — où ces sit in the schema.org hierarchy, the self-serving reviews rule, the 2024–2025 afficher changements, and qui article to lire suivant? Switch to the Avancé tab.
Trust markup que undermines trust
- Marking up testimonials à propos de votre propre business pour stars. Reviews controlled
by the reviewed
LocalBusinessorOrganizationare self-serving and ineligible pour Google’s examiner snippet. - Aggregating ratings copied from autre websites.
AggregateRatingdevrait décrire genuine ratings represented on lune page, pas a blended score scraped from third-party platforms. - Treating données structurées as a ranking boost. Ces types peut prise en charge rich presentation or entity understanding; ils ne faites pas créer a ranking augmenter.
- Keeping a WebSite
SearchActionparce que vous expect a sitelinks searchbox. Que fonctionnalité was deprecated November 21, 2024. The markup is harmless but inert;WebSiteitself remains utile pour site identity. - Assuming mobile breadcrumb afficher was the whole fonctionnalité. Google supprimé the
breadcrumb trail from the mobile result URL row in January 2025, pas the
BreadcrumbListtype or its desktop utiliser. - Publishing markup que disagrees with visible content. Examiner authors, ratings, counts, noms, and breadcrumb paths devrait remain truthful and visible to utilisateurs, pas exist seulement in JSON-LD.
TL;DR — “Metadata & Trust schema” is my practitioner grouping, pas a Google or schema.org category, pour the types que attach trust and orientation to ordinary pages plutôt que selling something: Examiner, AggregateRating, BreadcrumbList, and WebSite. Google doesn’t fichier les as a family, and leur documentation status is uneven — Examiner/AggregateRating and BreadcrumbList chaque have a live, dedicated fonctionnalité guide, pendant que WebSite is the odd un out, with aucun unique current guide and its la plupart famous fonctionnalité (le sitelinks searchbox) deprecated November 21, 2024. WebSite itself is pas deprecated — it encore helps Google comprendre a site’s nom. The sharpest rule is the self-serving reviews policy: a business can’t earn star snippets pour reviews of itself (scoped to LocalBusiness/Organization, pas Product). None of the four is a ranking factor or a documented E-E-A-T signal; ils buy eligibility pour a SERP treatment, pas trust. The risk is mostly mild — a manquant property or a self-serving examiner simplement costs eligibility — but deliberately misleading or fake markup peut encore draw a manual action sous Google’s general guidelines.
Premier, an honest framing: ce is my grouping, pas Google’s
Schema.org defines types and properties, but markup ne fait pas independently vérifier que claims are trustworthy. Evidence for this claim Official or primary documentation supporting the adjacent article claim, with scope limited to the source's published description. Scope: No ranking guarantee or undisclosed system mechanics are inferred beyond the cited source. Confidence: high · Verified: Schema.org schemas Google states que valid données structurées ne fait pas guarantee afficher as a rich result or ranking benefit. Evidence for this claim Official or primary documentation supporting the adjacent article claim, with scope limited to the source's published description. Scope: No ranking guarantee or undisclosed system mechanics are inferred beyond the cited source. Confidence: high · Verified: Google: Structured data policies
I vouloir to be transparent up front, parce que la plupart content que talks à propos de “trust” or “metadata” schema quietly implies ces types are an official family. They’re pas — the même disclaimer I faire pour commerce schema s’applique ici.
- Google’s propre docs don’t groupe les. In the données structurées gallery, “Breadcrumb” and “Review snippet” chaque sit as leur propre entries in the general Fonctionnalité guides liste — correct alongside unrelated types comme Article and Local business. WebSite doesn’t même obtenir a standalone feature-guide entry the façon the others do.
- schema.org doesn’t unify les. Examiner and AggregateRating are fermer cousins, but BreadcrumbList is a kind of liste, and WebSite is a kind of creative fonctionner — three différent branches of the vocabulary. There’s aucun shared parent que dit “ces four are the trust types.”
So pourquoi put les in un article? Parce que in pratique — the façon an SEO en réalité fonctionne — they’re the même kind of problem: content vous mark up pas to unlock a shopping or jobs fonctionnalité, but to establish que une page is credible, locatable, and partie of a réel site. Que shared utiliser cas is réel and utile. The shared taxonomy n’est pas. I’d plutôt dire que plainly que pretend Google drew ce box.
The four types En un coup d’œil
- AggregateRating (
schema.org/AggregateRating) — the summary rating: an average score plus a count, e.g. “4.6 stars from 312 ratings.” It’s ce que powers the star snippet on la plupart pages. Minimum pour a rich result:ratingValueplus au moins un ofratingCountorreviewCount, nested sous the chose it’s rating. - BreadcrumbList (
schema.org/BreadcrumbList) — lune page’s position in le site hierarchy, expressed as an ordered array ofListItemobjects. Google peut utiliser it to categorize lune page and (on desktop) montrer a breadcrumb trail in placer of the raw URL. Exige au moins twoListItementries, chaque with apositionand aname. - Examiner (
schema.org/Review) — a unique examiner, with anauthor, areviewRating.ratingValue, and the item it’s à propos de (itemReviewed). Multiple reviews on a page typically roll up into an AggregateRating pour the star afficher. - WebSite (
schema.org/WebSite) — the identity of le site itself, distinct from quelconque unique page. It une fois powered le sitelinks searchbox viaSearchAction; today its live valeur is helping Google comprendre a site’s nom pour afficher in results.
I garder ce hub deliberately shallow on chaque type’s property tables — the deep dives live in the four child articles I point to at the fin.
Où ils sit in the schema.org hierarchy
Ce is the partie almost nobody cites correctement, and it’s the difference entre a guess and a fact:
- AggregateRating —
Thing > Intangible > Rating > AggregateRating. A specialized kind of Rating. - Examiner —
Thing > CreativeWork > Review. A creative fonctionner, pas a rating — it carries a rating (reviewRating) plutôt que being un. That’s pourquoi Examiner and AggregateRating are cousins, pas the même type. - BreadcrumbList —
Thing > Intangible > ItemList > BreadcrumbList, construit fromListItementries. A liste type, unrelated to ratings. - WebSite —
Thing > CreativeWork > WebSite. A creative fonctionner comme Examiner, but a wholly différent objectif.
Conclusion: there’s aucun unique shared parent binding ces four. AggregateRating and Examiner les deux concern ratings but live in différent branches; BreadcrumbList is a liste; WebSite is a site. The connective tissue is the SEO utiliser cas — trust and orientation — pas type inheritance. Dire que, and you’re on solid ground.
Shared ground rules à travers tout four
Même though the types don’t share a taxonomy, ils share Google’s general structured-data guidelines, and it’s worth stating the rules une fois:
- Requis properties are the eligibility gate. Miss a requis property and lune page isn’t eligible pour que rich result. As Google puts it, items manquant requis properties ne sont pas eligible, and the plus recommended properties vous provide, the plus élevé quality the result is to utilisateurs.
- Eligibility ≠ guaranteed afficher. Valid markup obtient vous into the pool; Google’s systems encore separately decide si to montrer the enhancement. Google doesn’t guarantee votre données structurées va montrer up même si lune page is marked up correctement.
- Seulement mark up visible, accurate content. Aucun invisible markup, aucun fake reviews, aucun misleading données. Google is explicit à propos de pas marking up content que isn’t visible to readers and pas marking up fake reviews — qui lands hardest on ce groupe, since Examiner and AggregateRating are exactly the types personnes are tempted to fake.
- JSON-LD is the recommended format pour tout of les — easier to maintain at scale que inline Microdata/RDFa.
Ce que sets chaque apart
Examiner / AggregateRating: the self-serving reviews rule
Ce is the sharpest, la plupart myth-relevant rule in the whole groupe. Si the entity being
reviewed contrôle the reviews à propos de itself, its pages en utilisant LocalBusiness or quelconque autre
Organization type are ineligible pour the star examiner fonctionnalité. In plain terms: vous pouvez’t
mark up testimonials on votre propre homepage and expect stars pour votre propre business. Crucially,
ce restriction is scoped to LocalBusiness/Organization — it fait pas blanket-block
reviews of autre schema types comme Product. A store showing genuine customer reviews of a
Product it sells is a différent situation from a business rating itself.
A few plus rules worth carrying: the examiner content vous mark up doit be readily disponible and obvious to utilisateurs on lune page, and vous doit pas aggregate reviews or ratings scraped from autre websites. Examiner and AggregateRating are aussi usually nested sous the chose ils décrire plutôt que floating standalone — Google has clarified the nesting expectations pour how Examiner/AggregateRating attach to the reviewed item, so ce is worth getting correct in the child article.
BreadcrumbList: the la plupart “just do it” type — but afficher peut modifier
Breadcrumbs are the cheapest, lowest-risk markup ici. The un rule personnes miss: provide breadcrumbs que represent a typical utilisateur chemin to lune page, pas a mirror of votre URL structure, and don’t inclure the top-level domain or the current page itself as items. Aussi, the old data-vocabulary.org breadcrumb markup is ne … plus eligible — vous doit utiliser schema.org.
The lesson BreadcrumbList teaches meilleur is que a afficher surface peut disappear sans the underlying fonctionnalité or markup requirement going away. In January 2025 Google stopped showing the breadcrumb trail in l’URL row on mobile résultats de recherche — desktop was unaffected, aucun action was requis from site owners, and les deux the markup and the Search Console Breadcrumb report kept working as avant. The markup didn’t become useless; a unique afficher placement simplement went away.
WebSite: the odd un out (and the deprecated searchbox)
WebSite is the type que breaks the pattern — and que asymmetry is itself the finding.
- Le sitelinks searchbox is gone. WebSite’s
SearchAction(potentialAction) une fois powered the “Sitelinks Search Box.” Google announced its removal in an October 21, 2024 blog post and deprecated the visual fonctionnalité starting November 21, 2024, citing dropped usage; it’s been supprimé from the Résultats enrichis Tester and Search Console reports. Leaving the old markup in placer causes aucun errors and has aucun negative effect — it’s simply inert now. - WebSite itself n’est pas deprecated. Ce is the distinction personnes fumble. Seulement the searchbox utiliser cas went away. WebSite is encore partie of how Google determines a site’s nom pour afficher in results (a live fonctionnalité), and it remains schema.org’s canonical façon to identifier le site as an entity distinct from quelconque unique page.
- Thinner, scattered documentation. Unlike the autre three, WebSite has aucun unique current Google feature-guide page — its guidance is split à travers site-name documentation and the now-archived searchbox docs. That’s worth stating plainly: WebSite is the least feature-rich of the four pour Search today.
Fait ce schema aider SEO?
Aucun, pas rankings. John Mueller has been direct: “Données structurées won’t faire votre site rank meilleur.” Ce que it fait is earn eligibility pour a spécifique SERP treatment — star snippets (Examiner/AggregateRating), a breadcrumb trail (BreadcrumbList) — or, in WebSite’s cas, aider Google comprendre votre site’s identity. Conflating “I added schema” with “I’ll rank better” is the unique la plupart courant myth à travers tout four types.
Un plus myth worth naming directement, donné the “trust” in ce hub’s propre nom: none of ce is a documented E-E-A-T signal soit. E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is a framework Google’s human quality raters utiliser to judge content — it isn’t a scored input Google has said quelconque of ces four types feed into. “Trust” ici is my practitioner shorthand pour the reader-facing effect (stars and a breadcrumb trail lire as plus credible to a person scanning results), pas a claim que Google’s algorithm scores votre page’s trustworthiness parce que vous ajouté Examiner or AggregateRating markup. The même goes pour entity consolidation, Knowledge Panel inclusion, and AI-citation outcomes — nothing ici documents quelconque of ces four types producing ceux results soit; treat quelconque claim que ils do as unverified.
The risk profile is worth comparing with the commerce hub, but I don’t vouloir to overstate the gap. Commerce schema noms a spécifique manual-action risk: a stale, unremoved JobPosting. La plupart of ce que goes incorrect with ce groupe is milder — a manquant requis property or a self-serving examiner simplement drops lune page from eligibility; the markup obtient ignored plutôt que punished. But that’s pas the whole risk picture. Google’s general structured-data guidelines cover plus que eligibility, and ils appliquer to ces four the même as anything sinon: markup that’s invisible to utilisateurs, misleading, or construit from fake reviews peut encore draw a manual action, separate from le site’s ordinary ranking systems. So the honest framing isn’t “ces four peut jamais earn a manual action” — it’s que the courant échec mode ici (a manquant property, a self-serving rating) is ineligibility, pendant que deliberately deceptive markup carries the même general risk quelconque données structurées fait.
Où to go suivant
Ce hub is the map; chaque of ces is its propre deep dive nested sous it:
- AggregateRating schema — requis vs. recommended properties, the
ratingCountvs.reviewCountdistinction, and how AggregateRating relates to (and rolls up) individual Examiner markup. Commencer ici si vous vouloir the summary star rating on une page. - BreadcrumbList schema — the
ListItemarray structure, the “typical user path” rule vs. mirroring votre URL, and the January 2025 mobile afficher modifier. Commencer ici pour site hierarchy and breadcrumb trails. - Examiner schema — the self-serving reviews policy in detail, nesting sous
itemReviewed, and qui entity types peut and can’t earn star snippets. Commencer ici pour individual reviews and testimonials fait correct. - WebSite schema — the
SearchAction/sitelinks-searchbox history and its November 2024 deprecation, plus the still-live site-name fonctionnalité. Commencer ici si you’re wondering si WebSite markup is encore worth ajout in 2026.
Pour the wider picture, ce hub nests sous the broader structured données subcluster — Voir aussi the sibling schema markup and commerce schema hub articles là pour the vocabulary, formats, and deprecation cycle. And it tout lives in the on-page cluster, où données structurées sits alongside the rest of on-page SEO technique.
AI summary
A condensed prendre on the Avancé version:
- Ce que c’est: “Metadata & Trust schema” is Patrick’s practitioner grouping — pas a Google or schema.org category — pour the schema.org types que attach trust and orientation to ordinary pages plutôt que selling something: Examiner, AggregateRating, BreadcrumbList, WebSite.
- Pas an official family: Google’s gallery listes Breadcrumb and Examiner snippet as separate general feature-guide entries; WebSite doesn’t obtenir a standalone fonctionnalité guide at tout. schema.org has aucun shared parent pour the four.
- Hierarchy: AggregateRating =
Thing > Intangible > Rating > AggregateRating; Examiner =Thing > CreativeWork > Review(carries a rating, isn’t un); BreadcrumbList =Chose > Intangible > ItemList > BreadcrumbList(a list); WebSite =Chose > CreativeWork > WebSite. Aucun unique binding parent. - Ce que chaque fait: AggregateRating = summary star rating (
ratingValue+ratingCount/reviewCount); Examiner = a unique examiner (author,reviewRating,itemReviewed); BreadcrumbList = site hierarchy via ≥2ListItems; WebSite = site identity / site-name. - Shared rules: requis properties = eligibility gate; eligibility ≠ guaranteed afficher; seulement mark up visible/accurate content (aucun fake reviews); JSON-LD recommended.
- Self-serving reviews: a business can’t earn star snippets pour reviews of itself on
LocalBusiness/Organizationpages — scoped to ceux types, pas Product. - BreadcrumbList afficher modifier: January 2025, Google stopped showing the breadcrumb trail in l’URL row on mobile (desktop unaffected); markup and the Search Console report encore fonctionner.
- WebSite / sitelinks searchbox: the searchbox was announced gone October 21, 2024 and deprecated November 21, 2024 — inert but harmless to leave. WebSite itself is pas deprecated; it encore helps Google comprendre site noms.
- Risk profile: mostly mild — a manquant requis property or a self-serving examiner simplement costs eligibility, pas a manual action comme a stale JobPosting peut earn — but deliberately misleading or fake markup peut encore draw a manual action sous Google’s general structured-data guidelines, the même risk quelconque données structurées carries.
- SEO impact: pas a ranking factor (Mueller: “Données structurées won’t faire votre site rank meilleur”) and pas a documented E-E-A-T, entity-consolidation, Knowledge Panel, or AI-citation signal — it earns eligibility and aids understanding, pas trust.
Documentation officielle
Primary-source documentation pour the four metadata-&-trust types and the rules ils share.
Google — shared rules
- General données structurées guidelines — the eligibility principle, content-quality and spam policies (notamment “don’t mark up fake reviews”) que appliquer à travers tout four types.
- Données structurées search gallery — the source of truth pour ce que currently produces résultats enrichis; aussi où vous pouvez voir que Breadcrumb and Examiner snippet are separate general feature-guide entries and WebSite n’est pas.
Google — Examiner & AggregateRating
- Examiner snippet (Examiner, AggregateRating) données structurées — requis properties, the self-serving reviews policy pour LocalBusiness/Organization, and nesting sous the reviewed item.
- Making Examiner Résultats enrichis plus utile (2019 blog) — the background on the self-serving-reviews crackdown.
Google — BreadcrumbList
- Breadcrumb (BreadcrumbList) données structurées — requis
ListItemstructure, the “typical user path” guideline, and the schema.org-only requirement. - Simplifying the visible URL element on mobile résultats de recherche (Jan 2025 blog) — the mobile afficher modifier (desktop and Search Console unaffected).
Google — WebSite (site nom / archived sitelinks searchbox)
- Farewell, Sitelinks Search Box (Oct 2024 blog) — the October 21, 2024 announcement of the November 21, 2024 deprecation.
Schema.org (taxonomy)
Quotes from the source
On-the-record statements. Où une page exposes the text, the lien is a deep lien que jumps to the quoted passage. Everything sinon ici I’ve paraphrased from verified sources plutôt que quote directement.
Google docs — the shared eligibility principle
- “Specify all required properties listed in the documentation for your specific rich result type. Items that are missing required properties are not eligible for rich results. The more recommended properties that you provide, the higher quality the result is to users.” Jump to quote
Google docs — the anti-fake-reviews rule (sharpest pour ce groupe)
- The general guidelines direct vous pas to mark up content que isn’t visible to readers, and pas to mark up irrelevant or misleading content tel as fake reviews. Google aussi states que it doesn’t guarantee votre données structurées va montrer up in résultats de recherche même si lune page is marked up correctement. Paraphrased from the General données structurées guidelines; the exact-substring deep lien pour ces lines wasn’t verified in the source brief, so I’ve paraphrased plutôt que quoted.
Google docs — self-serving reviews
- Google’s review-snippet documentation states que si the entity being reviewed contrôle the
reviews à propos de itself, its pages en utilisant
LocalBusinessor quelconque autre type ofOrganizationdonnées structurées are ineligible pour the star examiner fonctionnalité. Paraphrased from the Examiner snippet documentation; relayed via the source brief sans a verified exact substring, so paraphrased plutôt que quoted.
John Mueller, Google — schema n’est pas a ranking factor
- “Structured data won’t make your site rank better.” Coverage Relayed via Moteur de recherche Roundtable’s coverage of Mueller’s statements; treat the phrasing as transcribed secondary reporting. Ce line is universal — it isn’t spécifique to ces four types.
Google — le sitelinks searchbox removal
- Google framed le sitelinks searchbox removal as usage-driven and partie of simplifying search results, announcing it in an October 21, 2024 blog post with the visual fonctionnalité deprecated starting November 21, 2024. Paraphrased. The principal blog post’s corps text wasn’t retrievable as a verified exact substring in the source brief (seulement reachable via secondary coverage from Moteur de recherche Roundtable / Moteur de recherche Journal), so I’ve paraphrased plutôt que quoted verbatim.
Metadata & Trust schema En un coup d’œil
The four types comparé
| AggregateRating | BreadcrumbList | Examiner | WebSite | |
|---|---|---|---|---|
| Ce que it marks up | A summary rating (average + count) | Une page’s placer in le site hierarchy | A unique examiner of an item | The identity of le site itself |
| schema.org hierarchy | Rating > AggregateRating | ItemList > BreadcrumbList | CreativeWork > Review | CreativeWork > WebSite |
| Google rich result | Star snippet | Breadcrumb trail (desktop) | Star snippet (via rating) | Helps determine site nom |
| Dedicated Google fonctionnalité guide? | Yes (Examiner snippet) | Yes (Breadcrumb) | Yes (Examiner snippet) | Aucun — piecemeal seulement |
| Minimum pour eligibility | ratingValue + un of ratingCount/reviewCount | ≥2 ListItems, chaque with position + name | author, reviewRating.ratingValue, itemReviewed | name + url (searchbox SearchAction now inert) |
| Encore active in 2026? | Yes | Yes (mobile URL-row afficher dropped Jan 2025) | Yes | Type yes; sitelinks searchbox deprecated Nov 21, 2024 |
| Sharpest rule | Don’t aggregate off-site ratings | ”Typical user path,” pas URL mirroring; schema.org seulement | Self-serving reviews blocked (LocalBusiness/Organization) | WebSite ≠ deprecated même though searchbox is |
| Stale/misuse risk | Loses eligibility | Loses a afficher surface | Loses eligibility; fake/misleading content risks a manual action | Inert markup, harmless |
Fast facts
- “Metadata & Trust schema” is a practitioner grouping, pas a Google or schema.org category — the four types share an SEO utiliser cas (trust + orientation), pas a taxonomy.
- Aucun shared parent. AggregateRating and Examiner les deux concern ratings but sit in différent branches; BreadcrumbList is a liste; WebSite is a site.
- Self-serving reviews are blocked pour
LocalBusiness/Organization— but que restriction fait pas appliquer to Product reviews. - The sitelinks searchbox (WebSite
SearchAction) was deprecated November 21, 2024 — inert but harmless to leave. WebSite itself n’est pas deprecated. - Breadcrumbs lost leur mobile URL-row afficher in January 2025 — desktop and the Search Console report are unaffected; the markup encore helps Google parse hierarchy.
- Pas a ranking factor — and pas a documented E-E-A-T signal. Ces earn a rich-result treatment or site-identity understanding, pas trust, entity consolidation, Knowledge Panel inclusion, or AI-citation outcomes.
- Risk is mostly mild: a manquant property or a self-serving examiner simplement costs eligibility, pas a manual action — but deliberately misleading or fake markup (pas seulement a stale JobPosting) peut encore draw un sous Google’s general structured-data guidelines.
