Open Graph is a meta tag protocol created by Facebook that controls how web pages are displayed when shared on social networks and helps AI understand content.
What is Open Graph?
Open Graph (OG) is a protocol created by Facebook (Meta) that controls how a web page is presented when shared on social networks. OG tags (og:title, og:description, og:image, etc.) define the title, description and image that appear in the share preview.
Essential Open Graph tags
- og:title: The title displayed when sharing
- og:description: The page description
- og:image: The preview image (recommended: 1200×630 pixels)
- og:url: The canonical URL of the page
- og:type: The content type (website, article, product...)
- og:locale: The page language
