Open Graph
Meta-tag protocol that controls how a page renders when shared on social platforms — title, description, image.
Definition
Open Graph is a set of HTML meta tags (og:title, og:description, og:image, og:url) originally introduced by Facebook to control link previews. It is now respected by LinkedIn, Slack, Discord, X, and most chat apps. Setting Open Graph tags is table stakes for any page expected to be shared; the og:image is what drives social CTR.
