How to fix non self canonical on Squarespace
Ensure every page's canonical tag points to that same page's own URL — fix any canonical that currently points to a different page unless the redirect is genuinely intentional.
Steps for Squarespace
- Squarespace outputs self-referencing canonical tags automatically for all page types.
- A non-self canonical in Squarespace almost always comes from a custom code injection. Go to Pages → click the affected page gear icon (Settings) → Advanced → 'Page Header Code Injection'.
- Look for a <link rel="canonical"> tag injected there and remove or correct it.
- Also check Settings → Advanced → Code Injection (site-wide header injection) for a stray canonical tag that applies to all pages.
- If you use a third-party SEO plugin connected via Developer mode, check that plugin's configuration.
<link rel="canonical" href="https://www.example.com/products/your-product-name/" />What is non self canonical?
A canonical tag is a small snippet of HTML code (rel="canonical") placed in a page's <head> section that tells Google: "This URL is the one I want indexed and credited." A self-referencing canonical means the tag on a page simply points back to that same page's URL. A non-self canonical means the tag on a page points to a different URL — effectively telling Google to ignore this page and credit another one instead. That instruction may be correct (for intentional duplicate pages) but it is frequently an accident that silently hides important pages from search engines.
When a canonical accidentally points to the wrong URL, Google treats the current page as a duplicate that should not be indexed. Your product, category, or content page disappears from search results — losing any organic traffic and sales it would have generated. Even if Google does crawl the page, any external links pointing to it pass their ranking power ("link equity") to the wrong destination. At scale — for example, a non-self canonical on every product page — this can wipe out an entire section of your organic traffic. Fixing stray canonicals is one of the highest-impact, lowest-effort SEO corrections you can make.
