Why it matters

Without og:title, og:description and og:image, shared links on social and messaging apps look plain.

How to fix it

Add the missing Open Graph tags to the head.

What this means

The page is missing one or more of the three core Open Graph tags: og:title, og:description and og:image. The evidence names the ones that are missing.

<meta property="og:title" content="Trail Running Shoes for Wet Weather">
<meta property="og:description" content="Grip-tested on wet rock, with waterproof uppers.">
<meta property="og:image" content="https://example.com/images/trail-shoe-1200x630.jpg">

Why it matters

Open Graph tags control the preview card when a page is shared on Facebook, LinkedIn, Slack, WhatsApp, iMessage and most other apps. They have no direct effect on Google rankings.

Without them, each app guesses: it may pull the wrong image, such as a logo or an icon, show no image at all, or cut text from the navigation. A strong preview gets more clicks when people share your pages, and sharing is how many pages earn their first visitors and links.

How to fix it

  1. Add the three tags to the head of every page template, filled from each page's own data: the title, the meta description, and the main image.
  2. Use an image of at least 1200 by 630 pixels with an absolute URL, including https://.
  3. Set a sensible default image, such as a branded card, for pages without their own image.
  4. Add og:url and og:type too, and twitter:card with the value summary_large_image for a large preview on X.

Most SEO plugins and CMS platforms can output these tags automatically once enabled.

Verify the fix

Recrawl and check the evidence no longer lists missing tags. Then test a page in the platforms' own preview tools, such as LinkedIn's Post Inspector or Facebook's Sharing Debugger, which also clear their cached previews.

How it affects your score

Finding this issue on any page costs the On-Page SEO score 0.5 points, plus up to 4 more depending on the share of crawled pages affected. A smaller improvement with a modest effect on its own.

Find the affected URLs

Open Crawl > Issues and pick Incomplete Open Graph tags. Each affected URL is listed with its evidence, and Copy URLs or Export URLs hands the list to a developer. The issue also appears in the Action Plan, ranked by impact (low) and effort (low), and in the issues CSV under the code og_missing. After fixing, run a new audit and use Compare to confirm the URLs moved to fixed.
