Structured Data & JSON-LD Validator

Structured data describes visible page content in a machine-readable form. Correct markup may make a page eligible for supported search features, but it is not required for Google AI Overviews or AI Mode and does not create a ranking or citation advantage by itself.

The useful checks are concrete: valid JSON, applicable schema.org types, absolute identity references, and properties that accurately match what readers can see. Google no longer shows FAQ rich results, HowTo rich results are deprecated, and Google says there is no special schema for generative AI search. Misleading, hidden, or irrelevant markup can lose rich-result eligibility or trigger enforcement.

This tool fetches the page's JSON-LD and reports syntax, coverage, and consistency risks. Advisory findings are CiteFuel checks, not Google metrics. See Google's structured-data policies and AI optimization guidance.

How to use

  1. Paste the URL of any page you want to test.
  2. We fetch the live page and extract all JSON-LD blocks.
  3. Review the findings — red items are invalid JSON; yellow items require a factual or applicability check; informational items are optional.
  4. Fix your schema in <head> and re-test. For a generated, validated block, run the full audit.

Frequently asked questions

Does schema markup help with AI citations?

Structured data can help search engines understand visible page content and can make a page eligible for supported rich-result features. It is not required for Google's AI features, there is no special AI schema, and valid markup does not guarantee ranking or citation.

What schema types matter most for AI visibility?

Use only schema types that accurately describe the visible page. Organization, WebSite, Article, and SoftwareApplication may be appropriate depending on the page. HowTo rich results are deprecated, and Google no longer shows FAQ rich results; neither should be added as an AI-ranking tactic.

My schema passes Google's validator but CiteFuel flags it — why?

Google's Rich Results Test focuses on markup supported for Google Search features. CiteFuel also checks JSON syntax, type coverage, absolute @id values, and common consistency risks. Its advisory findings are not Google ranking signals and cannot prove that an AI system will cite the page.
