Canonical tags for syndicated content

Canonical tags tell search engines which URL is the original when the same article appears on multiple sites, so syndicated copies don’t compete with your own post and ranking signals consolidate to your domain. sgaindex

How to set them for syndicated content

1. Publish on your own domain first and wait for it to be indexed (check in Google Search Console). startuphub
2. Republish the full article on the platform (Medium, DEV, Hashnode, LinkedIn, partner blogs). startuphub
3. Add a cross‑domain canonical on the syndicated copy pointing to your original URL:

   <link rel="canonical" href="[https://yourdomain.com/original-article-slug](https://yourdomain.com/original-article-slug)" />
   

   This must be in the <head> of the syndicated page, not the body. devryo

Platform‑specific setup

• Medium – Use “Import a story” and paste your original URL; Medium auto‑adds the canonical. You can also edit it manually in story settings. onetwothreesend
• DEV (dev.to) – In the post’s front matter (YAML at the top), set:

  canonical_url: [https://yourdomain.com/original-article-slug](https://yourdomain.com/original-article-slug)
  

  Then verify with View Source that the canonical appears. startuphub
• Hashnode – When creating/editing the draft, mark it as republished and provide the original URL, or use the RSS importer which sets canonicals automatically. linkbuildingjournal.co
• LinkedIn Articles / partner sites – If they support custom HTML/meta, ask them to add the canonical tag in the head; if not possible, request noindex on their copy instead. onetwothreesend

Best practices and pitfalls

• Always point the canonical from the copy → original, never the other way around. devryo
• Don’t self‑canonicalize the syndicated copy (it must reference your domain, not itself). startuphub
• Wait for indexing of your original before syndicating to reduce the risk of the copy being treated as canonical. startuphub
• Verify with View Source or an SEO tool that the canonical is present and correct on each platform. startuphub

Used correctly, canonicals let you syndicate widely (for reach and AI citations) without duplicate‑content issues or losing SEO credit. linkbuildingjournal.co
