What this checks

Every time someone pastes your URL into Slack, WhatsApp or LinkedIn, a preview card is generated from your tags. When the image is missing the card is a bare grey box, which measurably reduces clicks.

  • Preview title from og:title or the title tag
  • Preview description
  • Preview image

How to act on the result

  • og:image must be an absolute URL. Relative paths fail silently on most platforms.
  • 1200x630px works across every major platform.
  • Write the preview title for a human scanning a feed, not for a search engine.

Frequently asked

Why does my link preview show nothing?

Usually a missing og:image, or one specified with a relative path. Platforms need an absolute URL and many will not follow a redirect to reach it.

How do I refresh a cached preview?

Facebook, LinkedIn and Twitter each offer a debugger that forces a re-scrape. Other platforms cache for varying periods with no way to clear it.

Should the preview title match my page title?

It does not have to, and often should not. Your title tag is written for search results. The preview title is written for someone scrolling a feed.

Does this affect SEO?

Not directly. Better previews earn more clicks and shares, and shares occasionally earn links.
