LinkedIn logo in bubblesHave you ever posted to LinkedIn, and then wanted to update the image minutes or days later? If so, here's how to do it for the next time you need to switch images out!

Why does the old image appear and how do we fix it?

Here is what happens: The very first time you use the URL of your blog post, LinkedIn will cache the image and title. This makes sense from a data standpoint because many articles go viral and are reposted thousands of times. Sadly, these aren't mine... not yet anyway. LinkedIn will only grab the image and title once so it doesn't repeat the same lookup over and over.

To bust the caching, there is a very simple way to force LinkedIn to update the image and title. Just add a random query parameter to the end of the URL. For example, let's use the following URL:

https://www.marketpath.com/keeping-promises

This is the URL for the original blog post. To force LinkedIn to update their cache, simply append the value "?1" to the end like this:

https://www.marketpath.com/keeping-promises?1

You can change the number "1" to any other number as you update your title or image. Keep in mind, however, this isn't really updating LinkedIn's cache. LinkedIn sees this as an entirely different URL and performs a lookup for it. If you paste the original URL back in, it will still show the original image and title. 

That's all there is to it. LinkedIn offers a different way to customize the image of your LinkedIn post. But that requires a few more steps. Simply updating the URL is pretty easy.

I hope this little trick will help you when you need it.

Oh, and for the record, even though I poke fun, I do love my graphic designers. After all, they make my posts look so much better!
