Free Schema Validator - No Account Required

Is Your Schema Markup Optimized for AI Search?

Free schema markup validator with AEO scoring - see which schemas are missing and get an AI-search-specific completeness score.

What you receive

Full schema audit with AEO scoring

Unlike generic validators that only check if your markup is technically valid, AEOVisor scores whether your schema is complete enough to help AI engines cite you.

Schema markup is the fastest path to higher AI visibility. AI engines use structured data to extract, contextualize, and cite your content. Missing or incomplete schemas are the single most common AI visibility gap we see across thousands of audited pages.

AEO Schema Score (0–100)
All schema types found on the page (JSON-LD + microdata)
Critical missing schemas: FAQ, Organization, Article, HowTo, BreadcrumbList
Completeness % per schema type (which fields are present vs missing)
Field-level fix recommendations (unlock with free account)

How structured data drives AI search visibility

No - Google deprecated the original Structured Data Testing Tool and replaced it with the Rich Results Test, which only checks schemas eligible for Google's rich results (not all schema types, and not AI-search relevance). AEOVisor's Schema Validator checks a broader set of schemas (including ones that matter for AI citation but aren't covered by Google's rich-results-only tool, like Organization entity data and BreadcrumbList) and scores completeness specifically for AI search.
