Open Graph
Meta tags (og:title, og:description, og:image, etc.) for link previews and machine-readable page summaries, read by AI crawlers and social platforms.
Definition
Open Graph (OG) is a set of meta tags originally created by Facebook for link previews in social feeds. Tags live in the HTML <head> (e.g. og:title, og:description, og:image, og:url, og:type) and describe what the page is about. They are read by AI crawlers, chat apps, messaging platforms, and link-unfurling services.
Open Graph does not replace Schema.org or JSON-LD; it complements them by providing a compact, widely supported summary that agents and platforms use to understand and display your pages.
Relevance to GEO
Setting Open Graph tags on all key pages helps agents and AI search experiences show accurate titles, descriptions, and images when referencing your content.
