LinkedIn Post Inspector alternative: preview your LinkedIn link cards

We request the page with the header 'LinkedInBot/1.0 (compatible; Mozilla/5.0; Apache-HttpClient +http://www.linkedin.com)' and parse the Open Graph tags out of the returned HTML. The preview card is built only from what that single response contains.

LinkedIn keeps the preview data for a shared URL for about seven days, which is why an old image can keep appearing after you have changed the page. Running the URL through Post Inspector fetches it again and updates the stored copy.

LinkedIn's own guidance is an image with a 1.91:1 ratio at 1200 by 627 pixels, and it may leave the image out if the file is too small or cannot be fetched. Titles and descriptions are cut short in the feed, so put the important words first. If this test shows the tags but your posts still appear without a card, the usual cause is a redirect, a cookie wall or a firewall rule that treats LinkedInBot differently from our request.

LinkedIn is the primary professional networking platform with over 900 million members. When you share a link in a LinkedIn post, article, or message, LinkedInBot fetches your page to generate a link preview card with a title, description, and image.

LinkedInBot does not execute JavaScript. It reads the raw HTML response and extracts Open Graph meta tags (og:title, og:description, og:image) to build the preview. If these tags are injected client-side by a JavaScript framework, LinkedIn shows a generic preview - typically just the URL with no image, no title, and no description.

For B2B companies, SaaS products, and professional services, LinkedIn is often the most important social channel. A broken link preview on LinkedIn directly impacts content marketing effectiveness, company page engagement, and employee advocacy programmes. When team members share company links and the preview looks broken, it undermines credibility.

Pre-rendering ensures LinkedInBot sees your OG tags in the raw HTML, producing rich, professional link previews that drive clicks and engagement on the platform where your professional audience lives.
