Well, you learn something new every day, even when you've been in the content and SEO game for more than 13 years.  Recently, I was banned from Medium for duplicate content. You see, I have posted more than 550 articles on Medium, all of which I'm the original author, but I first had posted all of them on my own website blog at https://datadriven.design.  I figured I'd get flagged for this at some point, but pushed forward, because the awareness from Medium articles is pretty solid.  I have a new way to go in and let Medium know about the original post, using the Canonical URL option under the Advanced Settings.  Apparently, LinkedIn Articles also has this option, so I'll be doing it there as well.  Now, I highly recommend that businesses create content daily in the form of video, transcribe into written blogs, extract the audio, post to podcast outlets like Anchor, and then to YouTube, Instagram, LinkedIn, Facebook, Medium and Google My Business.   This is a way to post duplicate content, but keep the SEO juice.
