Fetching the page…

What this checks

Open Graph tags decide the title, description and image shown when your page is pasted into LinkedIn, WhatsApp, Slack or Facebook. Missing them does not affect rankings, but it turns every share of your page into a bare grey box.

  • og:title, og:description, og:image, og:url, og:type
  • Twitter card tags
  • Which are missing

How to act on the result

  • og:image is the one that matters most visually. 1200x630px is the safe size.
  • Use an absolute URL for og:image. Relative paths silently fail on most platforms.
  • og:title can differ from your title tag, and often should be less keyword-led.

Frequently asked

Do Open Graph tags affect SEO?

Not directly. They affect how often a shared link gets clicked, which affects traffic and sometimes links.

Do I need Twitter tags as well as Open Graph?

Most platforms fall back to Open Graph, so twitter:card is the main one worth adding. The rest are optional.

Why is my preview image not updating?

Platforms cache aggressively. Facebook and LinkedIn both offer a debugger that forces a re-scrape.

What size should the preview image be?

1200x630 pixels works everywhere. Anything under 600px wide gets shown as a small square thumbnail instead of a banner.
