LinkedIn preview not updating

Why this happens

LinkedIn's crawler scrapes a page when a URL is first shared and caches the result for roughly 7 days. Even after you update your og:image, LinkedIn keeps showing the old preview until the cache expires — or until you force a re-scrape.

A few other causes produce the same symptom:

• og:image is a relative URL (like /preview.png instead of https://…)
• The image is behind a login, firewall, or CDN access control
• The image file is too large (LinkedIn has an undocumented soft cap around 5 MB)
• The page was previously scraped before og:image was added

How to check

First, paste your URL into the Open Graph Checker to confirm that og:image is present, absolute, and publicly reachable. If the tag looks correct, the problem is almost certainly the cache.

Then open the LinkedIn Post Inspector (linkedin.com/post-inspector/) and enter your URL. It shows LinkedIn's current cached data and provides a button to request a fresh scrape.

How to fix

1. Verify og:image is an absolute HTTPS URL pointing to a publicly accessible image.
2. Use 1200×627 pixels — LinkedIn prefers a 1.91:1 ratio and crops tightly.
3. Keep the image under a few megabytes so LinkedIn's crawler can fetch it quickly.
4. Paste the URL into the LinkedIn Post Inspector and click Inspect to trigger a re-scrape.
5. Wait a few minutes, then share the URL again to confirm the updated preview appears.

Example

You update your homepage's og:image from a 200×200 logo to a proper 1200×627 banner. You share the link on LinkedIn and the old logo still appears. That's the cache — the tag is correct, but LinkedIn hasn't re-scraped yet. Running the URL through the Post Inspector clears it and the new image shows up within minutes.
