LinkedIn Post Inspector shows what LinkedIn’s crawler parsed for a URL and can refresh a cached preview. You still need correct tags on the public page first. This guide explains the official tool and free checks that catch errors before you inspect.
What is a LinkedIn Post Inspector alternative?
There is no full third-party replacement for LinkedIn’s cache refresh. The practical alternative workflow is: confirm tags in View Source, validate the first HTML response with a link preview checker, fix absolute og:image, then use Post Inspector only to scrape and clear LinkedIn’s copy.
What size should a LinkedIn preview image be?
Use a landscape file around 1200×627 (or 1200×630) as a working default. See the LinkedIn image size guide for crop notes.
| Step | Tool |
|---|---|
| Confirm raw tags | Browser View Source |
| Inspect first HTML response | Link Preview Checker |
| Create artwork | OG Image Generator |
| Rescrape LinkedIn cache | Post Inspector (official) |
Workflow
- Emit
og:title,og:descriptionand absoluteog:imagein the first HTML response. - Open the image URL in a private window (200, no login).
- Run the link preview checker on the canonical URL.
- Paste the same URL into Post Inspector and request a scrape.
- Share again in a new post if the feed still shows the old card.
