LinkedIn Open Graph Debugger
How LinkedIn link previews actually work.
•Dmytro Krasun
LinkedIn does provide an official Open Graph debugger, and it’s the fastest way to fix broken or outdated link previews.
The tool is called LinkedIn Post Inspector.
What Is the LinkedIn Post Inspector?
It’s LinkedIn’s Open Graph debugging tool. It:
- shows exactly what LinkedIn scrapes
- displays the preview image, title, and description
- lets you force LinkedIn to re-fetch Open Graph data
If a preview looks wrong on LinkedIn, this tool is your first stop.
How to Clear LinkedIn’s Open Graph Cache
- Open the LinkedIn Post Inspector
- Paste your URL
- Click Inspect
- Wait for the scrape to finish
- Re-check the preview
LinkedIn immediately refreshes its cache after inspection.
Why LinkedIn Images Don’t Update
The common reasons:
- LinkedIn cached the old preview
og:imageURL didn’t change- image is too small or slow
- image is not publicly accessible
Updating the image file alone often isn’t enough. The image URL matters.
What OG Tags Matter Most on LinkedIn
LinkedIn mainly uses:
og:titleog:descriptionog:image
Missing or invalid og:image usually results in:
- no preview image
- low-quality fallback
- unpredictable rendering
Quick Debugging Checklist
- OG tags exist in server-rendered HTML
og:imageis absolute and public- image is large enough for social previews
- preview refreshed via Post Inspector
Final Takeaway
Unlike most platforms, LinkedIn gives you a real Open Graph debugger.
If previews look wrong:
- inspect
- refresh
- fix
Use the Post Inspector, and LinkedIn previews become predictable instead of frustrating.
