Structured Data
Validator

Check if your schema markup is correctly implemented and see exactly which types have the most impact on AI citation potential.

// The Problem

Broken Schema is Costing You Traffic

A single syntax error in your structured data means losing rich snippets and falling behind competitors in both traditional and AI-powered search.

Invisible Rich Snippets

Missing required schema properties (like price on a Product or author on an Article) disqualifies your page from Google Rich Results, severely lowering organic CTR.

JSON-LD Parsing Errors

A single missing comma, unescaped quotation mark, or unclosed bracket in your JSON-LD breaks the entire script. Search engines silently ignore the broken block.

Outdated Vocabularies

Schema.org frequently deprecates terms. Using legacy properties generates warnings in Google Search Console, causing ongoing compliance issues.

// Our Solution

Intelligent, Real-Time
Schema Validation

AEO HUB's Structured Data Validator goes beyond simple syntax checking. We cross-reference your JSON-LD or Microdata against both the Schema.org vocabulary and Google's Rich Results guidelines — then tell you exactly why an error occurs and how to fix it.

→

Syntax Accuracy: Detects missing commas, unclosed brackets, and invalid JSON formatting.

→

Required Properties: Ensures mandatory fields like reviewRating for Reviews are present.

→

Data Type Validation: Verifies dates use ISO 8601 format and URLs are properly structured.

Valid vs Invalid JSON-LD
