Schema.org Checker – Free AI Score
The Schema.org Checker analyzes the markup on your website and evaluates how well AI assistants can understand your content. Score from 0–100 with concrete improvement suggestions.
What does the Schema.org AI Score check?
The AI Score analyzes the structured data (Schema.org) on your website and evaluates how well AI assistants like ChatGPT, Claude and Perplexity can understand your content.
JSON-LD, Microdata and RDFa are detected. Each Schema type (Product, Organization, FAQPage, etc.) has type-specific required fields with different weighting.
The industry comparison shows which Schema types well-optimized websites in your industry typically have – and what you're missing.
Priorisierte Improvement suggestions
are sorted by priority: Missing required fields with high weight are recommended first.
How Does the Schema.org Checker Work?
The Schema.org Checker analyzes your page's HTML source code for structured JSON-LD and Microdata markup. It checks which Schema.org types are present (e.g., Product, Organization, Article, BreadcrumbList), how completely the required fields are filled, and whether data quality meets the requirements of Google and AI assistants.
The AI Score (0–100) weighs various factors: existing markup types, completeness of properties, nesting depth and AI relevance. Scores above 70 are considered good, above 85 very good. For each missing or incomplete markup, you receive copy-paste ready code to add.
Schema.org and Generative Engine Optimization
GEO (Generative Engine Optimization) describes all measures to make your website visible to AI assistants. Schema.org markup is a key building block: the better your structured data, the more accurately ChatGPT, Claude and Perplexity can recommend your products with price and link.
Important Schema types for GEO: Product (with price and availability), AggregateRating (reviews), FAQPage (frequently asked questions), HowTo (guides) and Organization (company data). The AI score evaluates all these types and shows missing fields.
How to use the Schema.org AI Score Checker
Enter your website URL in the input field above and click Analyse. The checker crawls your homepage and extracts all available Schema.org markup. Within seconds, you receive a structured AI score from 0 to 100, broken down by schema type.
The results show which schema types are implemented correctly, which have missing fields, and which are absent entirely. Each finding includes a prioritized hint explaining what to add and where — whether on your homepage, product pages, or category pages.
After fixing the flagged issues and re-uploading your structured data, run the checker again to track your progress. A score above 70 significantly improves how AI assistants like ChatGPT, Claude and Perplexity understand and recommend your business.
