8. Allows Reposting of Content
Medium allows you to repost content that you originally wrote elsewhere (such as your blog) and share it on their platform.
There is a pervasive myth that:
“reposting content from your personal website on Medium will harm the SEO/domain authority of your site.”
This is totally false. This is addressed directly by Medium:
“Medium’s publication and cross-posting pathways automatically add canonical links to protect your original content posted offsite. This means that Medium can only boost — not cannibalize — your SEO.”
A more nuanced response:
The SEO impact depends on the timing of when you publish the post and how they interlink.
When Google encounters two pieces of content that are substantially similar, the algorithm has to decide which one was the “original” or “canonical” version and which ones are the duplicate versions.
The best practice is to always post on your own website first, and then submit the page for indexation to Google. After the page is indexed by Google, then it’s a much safer bet to cross post it to other places.
If you publish to Medium or first (before your own site), Google might consider the LinkedIn or Medium version to be the canonical. That means: from now on Google will show the Medium page instead of your own site when people search for your blog post on Google.
