## Definition

OpenGraph is a protocol using HTML meta tags to control how web pages are represented when shared on social platforms — providing title, description, and image metadata that social platforms use when generating link previews. It was developed by Facebook and is now supported by most major social platforms.

## Why It Matters for AI Search

OpenGraph metadata contributes to content clarity signals for AI systems that index social sharing activity. When content is shared on social platforms with accurate, entity-explicit OpenGraph titles and descriptions, it extends the brand's semantic footprint into social graphs. OpenGraph implementation is also a basic technical hygiene requirement for any brand treating social media as a citation and discovery surface.
