Fix what's flagged
Each problem links to a plain-English fix, with the exact tag to add. Re-run the check to confirm it is live.
How this compares with LinkedIn's Post Inspector
LinkedIn's own Post Inspector at linkedin.com/post-inspector needs you to sign in to LinkedIn. Inspecting a URL there also makes LinkedIn fetch it again, so it is the tool to use once your tags are fixed.
This checker needs no account and is not affiliated with LinkedIn. It shows the same preview, lists each tag it read, explains every problem it finds, and previews Facebook, X, WhatsApp and Discord from the same scan.
The tags LinkedIn reads
LinkedIn builds the preview from Open Graph tags and asks for four: og:title, og:image, og:description and og:url. In the feed it usually shows a compact card, with the image on the left and the title and domain beside it, so og:description may be left out there.
| Tag | Falls back to | Notes |
|---|---|---|
og:title | <title> | Clamped to two lines beside the image. |
og:image | None reliable | At least 1200 × 627; JPG, PNG or GIF under 5 MB. Shown small, so keep the subject centred. |
og:description | Meta description | May be left out of the feed card; set it for other platforms. |
og:url | The shared URL | The canonical URL LinkedIn attributes the share to. |
<meta property="og:title" content="Your page title" />
<meta property="og:description" content="One or two sentences." />
<meta property="og:image" content="https://example.com/og.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta property="og:url" content="https://example.com/page" />LinkedIn image size
LinkedIn lists 1200 × 627 pixels as its minimum, at a 1.91:1 ratio, so the standard 1200 × 630 Open Graph image works as it is. Images under 401 pixels wide show as a small thumbnail. Use JPG, PNG or GIF (animated GIFs up to 300 frames), under 5 MB.
Because the feed often shows the image small, keep text large and the subject in the middle. If an image meets the spec but still does not appear, LinkedIn says your site may be blocking its crawler or serving the image from a protected location.
