how to publish one article to dev.to, Substack, and Blogger automatically

TL;DR

Publish to dev.to, Substack, and Blogger from one canonical source: write the article once, set the canonical URL to your own site, adapt the formatting per platform, and schedule the posts staggered by a day or two. dev.to and Blogger have APIs; Substack needs its editor or email-to-post. Always check each platform's automation rules first.

how to publish one article to dev.to, Substack, and Blogger automatically

Use this when

• Syndicating a long-form article across platforms
• Running a regular publishing cadence
• Each platform's audience is worth reaching

Not for this skill when

• A platform prohibits automated posting (respect it)
• The article is platform-specific (write natively instead)
• You have not set canonical URLs (fix that first)

Steps

1. Write the canonical version on your own site first. This is the version search engines should rank; everything else points to it. Expected: a live canonical URL before any syndication.

1. Adapt per platform. dev.to takes markdown via API; Blogger takes HTML via API; Substack works best through its editor or email-to-publish. Expected: three platform-ready versions, not one pasted everywhere.

platform paths:
  dev.to:    API with markdown body
  Blogger:   API with HTML body
  Substack:  editor or email-to-post

1. Set canonical links on every copy. dev.to and Blogger both support canonical URLs; use them to point at your original. Expected: no duplicate-content confusion in search.

1. Stagger the publishes by a day or two. Same-hour blasts look automated and split the initial audience. Expected: three publishes across three days.

1. Log each publish with its URL. Expected: your publishing log shows all three copies and their canonicals.

Variant phrasings

cross-posting to dev.to Substack and Blogger

Canonical on your site, adapted formats per platform, canonical links set, staggered schedule.

automatic multi-platform article publishing

One source, three adapters, canonicals everywhere, logged.

syndicating blog posts across platforms

Write once, adapt per platform API, stagger, and always canonicalize.

Why it happens

Each platform has a distinct audience and its own formatting and API quirks, but the content is the same. A canonical-first workflow gets you the reach of three platforms with the SEO safety of one source of truth.

Edge cases / pitfalls

• Substack's automation surface is thin; do not fight it, use the supported path.
• dev.to rate-limits API publishing; check the current limits before batching.
• Blogger needs HTML, so keep a markdown-to-HTML step in the pipeline.
• If a platform rejects the post, read the reason; do not just retry.
