Schema Auditor

See exactly which schema types your URL is missing

No signup required. 5 free checks per day. Get a full technical SEO audit for unlimited access.

Schema markup is the most undervalued ranking signal in 2026. Pages with the correct schema stack appear in AI Overviews, rich results, and LLM citations at three to five times the rate of pages without. Most sites are missing 60% or more of the schema types they should have.

This tool scans any URL, identifies the page type, and tells you exactly which schema you have and which you should have. The full technical SEO service implements the missing schema plus the rest of the on-page foundation.

How It Works

From URL to actionable score

  • 1.Paste any URL on your site or a competitor URL.
  • 2.We fetch the page and extract every JSON-LD schema block.
  • 3.We classify the page type (product, blog, service, case study, listicle, etc.) based on URL pattern and content signals.
  • 4.We compare against the OnyxRank 100X playbook spec for that page type and flag missing or malformed schemas.

Frequently Asked Questions

Questions about this

Why does schema matter in 2026?+
Schema is the structured-data layer Google and LLMs use to understand what a page is and what it claims. Without schema, your page is text. With schema, your page is data with semantic relationships. AI Overviews and rich results pull almost exclusively from properly structured pages.
Which schema types do you check for?+
All 14 from the OnyxRank playbook: Organization, WebSite + SearchAction, Product, Service, BlogPosting, FAQPage, BreadcrumbList, Article, Review, AggregateRating, MerchantReturnPolicy, OfferShippingDetails, LocalBusiness, HowTo, VideoObject, CollectionPage, ItemList, and Person + sameAs.
My page has schema but the tool says it's malformed. Why?+
The most common issues are: (1) required fields missing (e.g., Product without Offer), (2) wrong @type for the content (e.g., Article on a product page), (3) Person schema without sameAs, (4) FAQPage without question-answer pairs. The tool surfaces each issue specifically.
Can I fix the issues myself?+
Yes. Our blog has a full library of schema implementation guides. If you want it done for you, the technical SEO service handles end-to-end schema deployment for the entire site.
Does this work for non-English sites?+
Yes. Schema is language-agnostic JSON. The audit checks structure, not content language.
