Core Open Graph tags

Threads reads the same OG tags as Facebook. If your tags work on Facebook, they work on Threads.

<meta property="og:title" content="Page Title">
<meta property="og:description" content="A brief description of the page">
<meta property="og:image" content="https://example.com/image.jpg">
<meta property="og:url" content="https://example.com/page">
<meta property="og:type" content="website">

See the Facebook tags page for the full breakdown of each tag and Facebook-specific extensions like fb:app_id (which Threads ignores but won’t choke on).

Image dimension hints

og:image:width and og:image:height let Meta’s crawler render the preview without downloading the image first. Without them, the first share may show a blank image slot while Meta processes it.

<meta property="og:image" content="https://example.com/image.jpg">
<meta property="og:image:width" content="1200">
<meta property="og:image:height" content="630">

Fallback behavior

Same chain as Facebook:

The heuristic image pick is unreliable: you’ll get a logo, a sidebar image, or nothing. Always set og:image explicitly.
