How to fix non self canonical on WooCommerce
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 WooCommerce
- WooCommerce relies on WordPress/Yoast/Rank Math to output canonical tags.
- If you use Yoast SEO: go to WordPress Admin → SEO (Yoast) → Search Appearance → check 'Advanced' settings. Per-page overrides live in the Yoast meta box at the bottom of each page/product editor → Advanced tab → 'Canonical URL' field. Clear any incorrect value.
- If you use Rank Math: WordPress Admin → Rank Math → Edit the page/product → the 'Advanced' tab in the Rank Math meta box contains a 'Canonical URL' field. Clear incorrect values.
- If canonical logic is in your theme, check your child theme's functions.php or a custom plugin for wp_head hooks that output rel=canonical.
- After fixing, use the URL Inspection tool in Google Search Console to confirm the canonical is now self-referencing.
<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.
