How to fix non self canonical on Squarespace
Audit every page whose canonical tag points to a different URL, then either correct it to self-reference or confirm the cross-reference is intentional and correct.
Steps for Squarespace
- Squarespace automatically outputs self-canonical tags on all pages — manual overrides are only possible via Code Injection.
- Go to your Squarespace admin, navigate to Settings → Advanced → Code Injection.
- Check the 'Header' code injection area for any <link rel="canonical" ...> tag that was manually added. If found and incorrect, either remove it entirely (to restore Squarespace's automatic canonical) or update the href to the correct self-referencing URL.
- Also check individual pages: open the affected page in the Pages panel, click the gear icon (Page Settings), select the 'Advanced' tab, and inspect the 'Page Header Code Injection' field for any hardcoded canonical tag — remove or correct it.
- Save changes and view-source the live page to confirm only one canonical tag exists and it matches the page URL.
What is non self canonical?
A canonical tag is a small snippet of HTML code, placed in the `<head>` of a page, that tells Google "this is the definitive version of this content." A self-canonical means the tag points back to the page itself — the norm for any page you want indexed. A non-self-canonical means the tag points to a different URL, effectively telling Google: "don't index me, index that other page instead." This is sometimes intentional (e.g., a filtered product-listing page deferring to the main category page), but when it happens by accident, Google will ignore the page entirely and index the wrong destination instead.
When a page has a non-self-canonical by mistake, Google treats it as a duplicate and removes it from search results — meaning all the organic traffic that page could earn is lost. If important product, category, or landing pages are accidentally canonicalized to the wrong URL, your store effectively disappears from Google for those queries. Even if Google doesn't fully honour the tag, it still dilutes your crawl budget and creates confusing ranking signals. Fixing accidental non-self-canonicals can restore lost rankings quickly, while verifying intentional ones ensures you're not accidentally de-indexing pages you need.
