How is this different from Google's Rich Results Test?

Google's tool returns pass/fail for a handful of schema types and tells you nothing about why an error matters.

What schema types are supported?

30+ types including Article, Product, FAQPage, Recipe, Event, LocalBusiness, VideoObject, HowTo, BreadcrumbList, JobPosting, Course, Review, Organization, WebSite, SoftwareApplication, Service, and more.

Can I validate schema from a live URL?

Yes. Switch to the "From URL" tab, paste any public URL, and the tool extracts and validates every JSON-LD script tag it finds on the page.

Does it handle @graph and deeply nested schema?

Yes. @graph arrays with multiple @types are parsed and each node is validated individually with its own field tree and error cards.

Will this help my content show up in Google AI Overviews?

Proper schema is one of the strongest signals AI Overviews uses to decide what to quote. Grigora flags the exact fields AI engines look for, author, datePublished, publisher, and explicit offers.

Do you store my code or URLs I validate?

No. The validator runs stateless, nothing is logged, stored, or shared. You can use it on staging and pre-release URLs safely.

Why does my schema validate here but fail on Google's tool?

Usually one of three reasons: (1) Google only supports a subset of schema types for rich results; (2) your page blocks Googlebot from rendering client-side JS that injects the schema; (3) the schema references an image URL Google cannot reach.

Does schema work with React, Next.js, Shopify, Webflow, WordPress?

Yes, the validator runs on the final rendered HTML, so it works with every platform. For React and Next.js, make sure you render JSON-LD server-side (with next-seo or next/head) so crawlers can see it.

Can I validate multiple schemas on one page at once?

Yes. Grigora detects every schema block and validates them in a single run, each gets its own detected-types panel, tree view, and error cards.

What's the difference between JSON-LD, Microdata, and RDFa?

All three are Schema.org formats. JSON-LD is Google's recommended format, it lives in a single script tag, is easy to maintain, and has no effect on your HTML.

Most common errors

Common schema errors & how to fix them

Based on thousands of validations run through Grigora.

Missing @context

Cause: The JSON-LD block has no "@context" or uses "http://" instead of "https://".

Fix: Add "@context": "https://schema.org" as the first property.

Missing @type

Cause: "@type" is omitted or mis-capitalized (e.g. "type" or "@Type").

Fix: Use the exact case: "@type": "Article".

headline too long

Cause: Article headlines over 110 characters are rejected for Top Stories.

Fix: Trim to under 110 characters or move the long summary to description.

Missing offers (Product)

Cause: Product schema without a price won't show rich results.

Fix: Add offers with price, priceCurrency, and availability.

Invalid date format

Cause: datePublished uses "20 April 2026" or "4/20/2026".

Fix: Use ISO 8601. "2026-04-20" or "2026-04-20T09:00:00+05:30".

image is not a URL

Cause: You passed a relative path like "/hero.jpg".

Fix: Use the full absolute URL: "https://example.com/hero.jpg".

Duplicate @id

Cause: Two nested entities in a @graph share the same @id.

Fix: Give each @graph node a unique @id fragment (e.g. #org, #website).

aggregateRating without reviewCount

Cause: Ratings with no review count are ignored by Google.

Fix: Include reviewCount (or ratingCount) with a positive integer.

FAQPage with one question

Cause: Single-question FAQPage entities look spammy and get dropped.

Fix: Add at least three real, non-duplicate questions inside mainEntity.

Event in the past

Cause: Events with startDate in the past are ignored.

Fix: Update startDate to a future date or remove the Event schema.

Invalid JSON syntax

Cause: A stray comma, unclosed bracket, or smart quote breaks the entire block.

Fix: Run the full JSON through the validator, it points to the exact line.

LocalBusiness missing address

Cause: LocalBusiness needs a full PostalAddress, not just a city string.

Fix: Use a nested PostalAddress with streetAddress + addressLocality + addressCountry.
