Open Graph (OG) is a protocol created by Facebook that uses meta tags to control how web pages appear when shared on social media, including title, description, and image. Twitter Cards use similar tags.
Social platforms cache OG tag information. If you've updated tags but the preview hasn't changed, use Facebook Sharing Debugger or Twitter Card Validator to force a cache refresh.
Facebook recommends 1200Γ630px, Twitter large card 1200Γ600px, LinkedIn 1200Γ627px. We recommend at least 1200Γ630px for compatibility across all platforms.
