What are Open Graph tags?
Open Graph is a protocol, created by Facebook, that lets a web page describe how it should look when shared: its title, description, image and type. LinkedIn, WhatsApp, Slack, Discord and many others read the same og: tags. X reads its own twitter: tags and falls back to Open Graph.
Without these tags, networks guess, often picking a random image or the wrong text. A clear title, a short benefit-led description and a 1200 × 630 image with readable text make shared links far more clickable.
Questions about the Open Graph & social preview generator.
Can't find what you're looking for? Ask us directly.
What size should an OG image be?
1200 × 630 pixels (a 1.91:1 ratio) works across Facebook, LinkedIn, X and WhatsApp. Keep important text away from the edges.
Why is the old image still showing?
Networks cache previews. Use Facebook’s Sharing Debugger or LinkedIn’s Post Inspector to fetch the page again.
Do I need both og: and twitter: tags?
X falls back to Open Graph for most fields, but twitter:card is needed to choose the large image layout.
