Why Schema.org for AI Visibility?

Structured data helps AI systems and search engines understand content, entities and sources more reliably. Schema.org is the established standard for machine-readable context data; display, citation or adoption remain external decisions.

Products become machine-readable with price, availability and verifiable reviews

FAQs receive a clear question-answer structure for potential citations

Local businesses become clearer through address, opening hours and services

How-to guides become easier for machines to evaluate as structured steps

From one-off check to ongoing scanner

The free validator checks one markup block. The paid Website Scanner monitors pages, products, services, feeds, rechecks and reports inside the dashboard.
