How to publish the same article on both platforms without SEO penalties
The most common concern about dual publishing is duplicate content penalties. The solution is canonical URLs. Medium supports canonical tagging — when you import or cross-post an article, you can set a canonical link pointing to the original source. This tells Google which version to index and credit, preventing duplicate content issues.
The recommended workflow: publish on your primary platform first (usually Substack for subscriber ownership), then cross-post to Medium two to four hours later with the canonical URL set to the Substack version. Medium accepts imported content with canonical tags, so you get algorithmic discovery on Medium without splitting your SEO authority.
Narrareach handles canonical URL management automatically during the dual-publish workflow. Write the article once, set Substack as the primary source, and Narrareach configures the Medium version with the correct canonical tag so both versions coexist without SEO penalties.
- Always set a canonical URL when cross-posting to prevent Google from choosing the wrong version to index
- Publish on Substack first, then Medium two to four hours later — this establishes Substack as the canonical source
- Use Narrareach to automate canonical URL configuration during the scheduling pass
- Check Google Search Console periodically to verify the correct version is being indexed for each article
