How to clear the cache of LinkedIn sharer manually

Content shared via LinkedIn is cached by LinkedIn's servers for a period of ~7 days. There is presently no way to manually clear the cache other than waiting for it to expire.

One possible short-term work-around is to modify your URL with a "garbage" parameter at the end of it, e.g. http://example.com/mypage.html?donothing=1

Provided your site does not change the content displayed based on the parameter you append, LinkedIn will see that as a different URL and you won't get the old cached version.

LinkedIn provides Post Inspector which obviously clears the preview cache.

Just debug your cached url in https://www.linkedin.com/post-inspector/inspect/.

It worked for me.

Try passing the &summary="Your short description" in the url, as BBC does:

https://www.linkedin.com/shareArticle?mini=true&url=http%3A%2F%2Fwww.bbc.com%2Fnews%2Fworld-europe-35602288&title=Ankara%20blast%3A%20Turkey%20PM%20says%20Syria%20Kurds%20to%20blame&summary=Turkey%27s%20prime%20minister%20says%20the%20deadly%20bombing%20in%20Ankara%20was%20carried%20out%20by%20Kurdish%20YPG%20militia%20based%20in%20Syria%2C%20and%20nine%20people%20have%20been%20arrested.&source=BBC

This way it wont look to load it from your page's OG tags and it wont get cached. Worked for me
