How to Cross-Post to Medium, Dev.to and Bluesky Without Hurting Your SEO

Republishing content on other platforms can widen an audience, but it risks those copies outranking the original on search engines. Setting a canonical URL signals to search engines which version is the source, and both Medium and Dev.to support this through their publishing tools or APIs. Bluesky, being a social network rather than a blog host, is better suited to a short teaser that links back to the full article. The recommended sequence is to publish on your own site first, allow about a day for indexing, then cross-post with the canonical URL set. A content publisher plugin can automate this process across platforms.
