The Canonical Page Strategy Every Author Needs

What this article covers: What canonical URLs are, why the publishing sequence matters for SEO, how to set canonical tags on Medium and other platforms, and why this is the single most important SEO decision an author can make when publishing across multiple platforms.
The research: Google's canonical URL specification and documentation, SEO research on duplicate content and domain authority accumulation, Medium's canonical import function, and patterns observed across successful author multi-platform strategies.
Key points: The canonical tag tells search engines which URL is the original, directing all search authority to your owned domain. The 24-48 hour publish-on-website-first sequence ensures your URL is indexed before Medium or Substack. Setting canonical correctly does not affect Medium distribution or curatability.
The takeaway: Every article published anywhere except your website first is building someone else's domain authority. The canonical page strategy changes this without reducing reach on any platform.
Most writers who publish on Medium and Substack know, in some vague way, that they "should have their own website." What they often don't know is the specific mechanism that makes the website matter — or that without it, every article they publish is building the platform's search authority, not theirs.
The mechanism is the canonical URL.
What Canonical Actually Means
When Google crawls the internet, it encounters the same content at multiple URLs constantly: the same article might be on your website, syndicated on Medium, published to Substack's public archive, and linked from Pinterest. Google has to decide which URL is the original — which one to credit with the search ranking and the domain authority that comes with it.
The canonical tag is the instruction set for this decision. It is an HTML element, placed in the head of a page, that says: "The authoritative version of this content is at this URL." When Medium has a canonical tag pointing to your website, Google reads that tag and credits your website with the article. When it doesn't, Google has to guess — and it may guess wrong.
The formal syntax is: <link rel="canonical" href="https://yourdomain.com/your-article-url" />. This tag lives in the <head> of the HTML. Most content management systems (including Next.js, WordPress, and Squarespace) provide a field for setting this without touching HTML directly.
The Sequence That Determines Who Gets Credit
The canonical tag is not the only mechanism that determines search credit. The timing of indexing also matters.
If you publish the same article on Medium before your website, and Google indexes Medium's version first, Medium becomes the canonical source in Google's model — even if you later add a canonical tag pointing to your website. The tag is one signal; the timestamp of first indexing is another. When they conflict, first indexing often wins.
The correct sequence:
Day 1 (or longer): Publish on your website. Submit the URL to Google Search Console for indexing. Wait.
Day 2-3: Once the article is indexed on your site (verify by searching site:yourdomain.com/article-slug on Google), publish on Medium with the canonical URL set to your website URL.
Day 3-7: Distribute to Substack and other platforms, each pointing back to your website version.
The 24-48 hour window is typically sufficient on an active domain with some existing authority. A very new domain may need longer.
Setting the Canonical on Medium
Medium's import function is the most direct path. Navigate to medium.com/new-story and select Import a Story. Enter the URL of your article on your website. Medium imports the article with the canonical URL already set to your website URL, requiring no additional configuration.
If writing directly on Medium, the canonical URL is set through the story settings: the three-dots menu in the editor, then Story Settings, then Canonical URL. Enter your website URL for the article there.
Either way, the result is a Medium article that Medium's readers see and engage with fully, while Google credits the search authority to your domain.
What This Compounds Into
A writer who publishes 200 articles over two years and sets canonical URLs correctly has been building domain authority on their owned domain for two years. A writer who publishes 200 articles without canonical URLs has been distributing that authority between Medium, Substack, and their own site, with no single destination building compounding authority.
Domain authority is not a linear asset; it compounds. A domain with 200 well-canonically-tagged articles has more search authority than 200 articles distributed across three domains — because Google's assessment of the domain's overall authority is influenced by the concentrated quality and quantity of content at one URL.
The canonical page strategy is not technically complex. It is one HTML tag and a publishing sequence. The compounding effect of getting it right, over two years, is significant.

Frequently Asked Questions
- What is a canonical URL and why does it matter?
- A canonical URL is the URL designated as the original, authoritative source of a piece of content. The canonical tag is an HTML element placed in a page's head that says to search engines: 'This is the original version of this content. If you find the same content at multiple URLs, credit this one.' When the same article appears on your website, Medium, and Substack, Google needs to determine which URL to index as the original — and which to treat as secondary. Without canonical tags, Google may split the search authority between all three, or deprioritize all of them as duplicate content. With canonical tags set correctly, your website URL gets credited with the full search authority, while Medium and Substack still distribute the article to their audiences.
- What is the correct publishing sequence for canonical pages?
- The sequence is: 1) Publish on your website (your owned domain). 2) Wait 24 to 48 hours for Google to index your page. 3) Publish on Medium, setting the canonical URL in the import tool to your website URL. 4) Publish on Substack, linking back to your website URL in the post. The waiting period is critical: if Medium or Substack publishes first and gets indexed before your site, Google will designate their URL as the original. Your site then becomes the copy. First indexed, first credited. The 24-48 hour window is typically sufficient for Google to index a new page on an active domain, though the exact indexing time varies.
- How do you set a canonical URL on Medium?
- When importing a story to Medium, the import tool asks for a canonical URL. Enter the full URL of the article on your own website — for example, https://nikitadatar.com/blog/article-slug. If you are writing directly on Medium rather than importing, you can set the canonical URL in the story's settings (the three dots menu, then 'Story settings,' then 'Canonical URL'). This setting tells Medium and Google that the content originated at your website URL, which is where the search authority should accumulate. Without this setting, Medium's URL gets the credit instead.
- Does setting a canonical URL affect your reach on Medium?
- Setting a canonical URL on Medium does not affect your article's distribution, curatability, or reach on Medium. The canonical tag is a signal to search engines only — it does not change how the article appears to Medium readers or editors. A canonically-tagged article can still be curated by Medium, submitted to publications, and read by Medium subscribers in exactly the same way as an article without a canonical tag. The difference is purely in which URL accumulates search engine authority.
- What about Substack — does it support canonical URLs?
- Substack does not currently offer a direct canonical URL field in the same way Medium does. The most effective approach for Substack is to explicitly link back to your website version in the article itself (typically in an introductory note: 'This article was originally published at [link]') and to use your website as the primary publishing destination before the Substack version goes out. Google's crawlers will generally follow the explicit link signal, and Substack's format (behind email/subscriber wall for paid posts) means that the public web version is often your website URL anyway. The canonical situation on Substack is evolving, and the platform may add direct canonical support in future updates.
