What are Open Graph tags?

Open Graph tags are meta tags starting with og: that tell social networks how to render a link preview. They control the title, description, and image shown when the URL is shared.

Why does my preview look different on each platform?

Facebook, Twitter, and LinkedIn each render previews slightly differently. Twitter also supports twitter: tags which can override or supplement og: tags for Twitter cards.

Why is my image not showing?

The og:image must be an absolute URL that is publicly reachable. Relative URLs and images behind logins or paywalls will not load in the preview.

How long until my changes appear?

Social platforms cache link previews. After updating your tags, use the platform debugger (like Sharing Debugger for Facebook) to force a refresh. This tool fetches the live page each time.
