Check your link before you post
A LinkedIn post stays in people’s feeds for a while, so a missing image or a cut-off title is worth catching first. This checker fetches your page, shows the card it expects LinkedIn to build, and lists each problem with its fix.
It’s an independent tool and the preview is an approximation. For LinkedIn’s own view of your page, and to refresh its copy, use its Post Inspector (opens in a new tab). Our checker adds the health score, framework snippets and previews for seven other platforms.
The tags LinkedIn asks for
LinkedIn’s help page (opens in a new tab) names four Open Graph tags that must exist on a shareable page:
<meta property="og:title" content="Your page title">
<meta property="og:description" content="One or two sentences about the page.">
<meta property="og:image" content="https://example.com/images/card.jpg">
<meta property="og:url" content="https://example.com/blog/my-post">LinkedIn’s feed card doesn’t show a description, so the title and image do the work. Still include og:description: LinkedIn lists it, and other platforms display it. Titles can run to about 150 characters, but a shorter one reads better in a feed.
LinkedIn image requirements
- Size: LinkedIn lists a minimum of 1200×627 pixels. The common 1200×630 Open Graph image meets it.
- Ratio: 1.91:1, which LinkedIn recommends.
- File size: up to 5 MB.
- Thumbnail layout: an image narrower than 401 pixels appears as a small thumbnail instead of a large image.
These figures are from LinkedIn’s help page and can change. The cheat sheet compares them with other platforms.
Why your LinkedIn preview isn’t showing
- You get a small thumbnail: the image is narrower than 401 pixels. Export a larger one.
- The image meets the rules but doesn’t appear: LinkedIn says your site may be blocking it from pulling the image, or the image may be in a protected directory. Check firewall and bot filter rules for
LinkedInBot. Our checker uses its own user agent, so it can’t confirm LinkedIn gets through. Post Inspector can. - The image URL can’t be used: it’s relative, or it needs a login or cookie. Use an absolute, public https URL.
- The title is wrong:
og:titleis missing, so LinkedIn fell back to the page’s<title>, which often includes your site name. - The tags are added by JavaScript: link preview crawlers don’t run it, so the tags must be in the HTML your server sends.
Refreshing a preview LinkedIn has cached
LinkedIn keeps the preview it built for a URL, so changing your tags doesn’t update it straight away. Paste the URL into Post Inspector to make LinkedIn fetch the page again, and do this before you write the post. A post you’ve already published may keep its old card, so you may need to repost it. Then check your page again to confirm the tags are right.
