Open Graph Tag Inspector
Paste your page head or meta tags to find missing fields, duplicates, relative URLs, and incorrect Twitter attributes.
Analysis runs in your browser. Pasted HTML is parsed as an inert document and is never uploaded or executed.
What the inspector can verify
It parses the same meta elements a crawler receives, identifies the four required Open Graph properties, and checks useful image and description fields. It also distinguishes Open Graph's property attribute from Twitter Card's conventional name attribute.
Duplicate values are reported in source order. The Open Graph protocol gives the first value preference when a property has multiple entries, so an old image placed first can explain a surprising preview.
This is a markup check, not a crawler emulator. It cannot prove that a social network can reach your server, download the image, or refresh a cached share.
Primary references
The checks follow the Open Graph protocol. Platform rendering and limits change independently, so confirm final behavior with the publisher's current documentation and debugger.
