Check how a page looks to search engines and AI crawlers.
Every result comes from code that fetches and parses the page. Nothing is guessed, and nothing about the pages you check is stored.
The four tools
-
Meta Tag & Open Graph Analyzer
Checks title, description, canonical, robots, hreflang and social cards.
-
Structured Data Validator
Extracts JSON-LD, microdata and RDFa and checks types, properties and @id references.
-
Headers, Robots.txt & Sitemap Checker
Follows redirects and checks HTTPS, HSTS, caching, compression, robots.txt and the sitemap.
-
AI Crawler Access Checker
Shows which AI crawlers robots.txt allows, and whether content is in the raw HTML.
Where this domain comes from
