How it works
The pasted markup is scanned in your browser for head tags and their attributes. The tool then runs ten focused checks covering character encoding, viewport, title, meta description, canonical link, robots directives, Open Graph, Twitter cards, duplicate meta tags, and risky or obsolete tags. Each finding explains what was found, why it matters, and how to fix it. Nothing is ever sent to a server.
