Schema AI-Visibility Tester

Schema markup AI visibility refers to whether your JSON-LD structured data is correctly implemented and interpretable by AI retrieval systems, not just traditional search engines. There is a meaningful difference between schema that satisfies Google's rich-result requirements and schema that maximizes AI citation probability.

AI systems parse structured data to extract authoritative entities, definitions, and factual claims. FAQPage schema makes Q&A pairs directly extractable as citable answer units. HowTo schema structures procedural content for AI step-extraction. Article schema with author and datePublished signals recency and E-E-A-T to AI ranking systems. Malformed schema — even schema that passes Google's validator — can confuse AI parsers if required AI-relevant fields are absent or if the structured data contradicts the visible page content.

This tool fetches your page's JSON-LD live and validates it against both structural requirements and AI-specific citability heuristics.

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 break AI parsing; yellow items are missed opportunities.
  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?

Yes. AI systems use structured data to extract discrete, citable facts. Pages with valid FAQPage schema are more likely to appear as direct-answer sources in ChatGPT, Perplexity, and Google AI Overviews.

What schema types matter most for AI visibility?

FAQPage and HowTo for direct-answer extraction. Article with author/dateModified for E-E-A-T. Organization and WebSite at the root level for entity disambiguation.

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

Google's validator checks required fields for rich results. Our tester checks additional AI-specific signals: schema-to-content consistency, entity descriptions, and whether JSON-LD @id values are domain-locked and resolvable.
