Check the public metadata behind a Bluesky website card.

Paste the final public URL below. LinkGlimpse follows redirects, reads the server-rendered metadata, checks the share image, and shows a representative card. It cannot reproduce every Bluesky client, clear a client cache, or guarantee the final crop.

How Bluesky Link Previews Use Metadata

A Bluesky website card carries a URL, title, description, and thumbnail. The official Bluesky posting guide demonstrates creating those fields from og:title, og:description, and og:image. LinkGlimpse inspects those public signals without posting to Bluesky.

Key metadata to check

  • og:title - The title of your content
  • og:description - A brief description
  • og:image - The image to display
  • og:url and the canonical - Signals for the intended page URL

What the Bluesky Preview Checker Tests

  • The HTTP response, final URL, and redirect path returned by the public page
  • Open Graph and Twitter Card values available in the server-rendered HTML
  • The share image response, format, byte size, and detectable dimensions
  • Canonical and robots signals that can reveal a deployment or indexing mismatch
  • Copy-ready fixes, a shareable report, and an AI remediation prompt for detected problems

How to Fix a Missing Bluesky Link Preview

  1. Paste the final public URL and run the checker.
  2. Confirm the page returns a successful HTML response and the expected final URL.
  3. Add one non-empty title, description, and absolute HTTPS image value where a diagnostic is missing.
  4. Make sure the image is public, returns an image content type, and does not require cookies or authentication.
  5. Deploy the fix and rerun the same URL before sharing it again.

If the live metadata is correct but an existing post still looks stale, the remaining difference may be client-side caching or rendering that LinkGlimpse cannot control.

Bluesky Link Preview Questions

How does Bluesky create a link preview?

Bluesky website cards include a URL, title, description, and thumbnail. The official Bluesky example reads og:title, og:description, and og:image from the linked page before creating the card.

Does this tool show the exact Bluesky card?

No. LinkGlimpse shows a representative preview from the public metadata it can fetch. Bluesky clients can apply their own rendering, cropping, caching, and moderation behavior.

Why is my Bluesky link preview missing or outdated?

The public page may have missing or unreachable Open Graph tags, a blocked image, a redirect problem, or metadata that changed after a client cached the link. Validate the deployed page first, then share the final public URL.

Which tags should I check for a Bluesky card?

Start with one non-empty og:title, og:description, and absolute HTTPS og:image. Also verify the page response, final URL, canonical, robots directives, and image response.
