# LinkedIn Post Inspector Alternative — Link Preview

## What LinkedIn needs

- LinkedIn builds the card from `og:title`, `og:description`, `og:image` and `og:url`.
- Image: at least 1200×627 pixels, a 1.91:1 ratio, at most 5 MB.
- The page is fetched by `LinkedInBot`; it has to reach the page without a login or a bot challenge.
- LinkedIn documents Post Inspector as the way to refresh a preview after you change the tags.

## LinkedIn link preview not showing or not updating?

- No image or a small one? LinkedIn documents 1200×627 as the minimum — smaller images show small or not at all.
- Keep the file under 5 MB and the URL absolute (https://).
- Changed the tags? Paste the URL into Post Inspector (signed in) to make LinkedIn fetch the page again; existing posts keep their old card.
- Check that robots.txt and your firewall let `LinkedInBot` in.
- Avoid redirect chains and login walls on the shared URL: the crawler sees what an anonymous visitor sees.

## Questions

### Can I use LinkedIn Post Inspector without an account?

No, Post Inspector needs you signed in to LinkedIn. This page previews the LinkedIn card from your tags with no account; to force LinkedIn itself to refresh its cache, you still need Post Inspector.

### What is the LinkedIn link preview image size?

LinkedIn documents a minimum of 1200×627 pixels, a 1.91:1 ratio and 5 MB at most. 1200×630 meets all three.

### Why does LinkedIn show an old image?

LinkedIn caches previews. Run the URL through Post Inspector after the change; a post you already published keeps the card it had.
