Syndicate content to Medium as a distribution channel?

hi

i saw the following in the documentation: “Don’t forget: You can also publish content to your Ghost site and then syndicate it to Medium as a distribution channel.”

I have two questions:
how does it work exactly?

won’t i be penalized by google SEO for having the same article in different places?

thanks!

Here’s a good how-to for syndicating to Medium

As the guide mentions, you won’t be penalized for SEO because the link on Medium will point back to your Ghost site as the canonical version (using the rel="canonical" attribute). This tells search engines that this isn’t duplicate content — instead, it says the content is syndicated and points back to the original (canonical) source.

thank you very much!
