Why it matters for a small business site
The same page often loads at several addresses: with and without www, with tracking codes on the end, with or without a trailing slash. A canonical tag tells Google which one to show, and which to count links towards, instead of leaving it to guess.
How to check yours
- View the page source and look for <link rel="canonical" href="…">.
- Check it points to the page’s own preferred address (https, and your chosen www or non-www form).
- In Google Search Console, URL Inspection shows which address Google chose as the canonical.
What good looks like
Every page has a canonical that points to itself at its one preferred address, the other versions redirect there, and your internal links use that same address. Google treats a canonical as a strong hint, not a command.
Common mistakes
- Every page’s canonical pointing to the home page, a common template bug.
- Canonicals that point to http:// or to a staging address.
- A canonical to one address while the sitemap and internal links use another.
- Pointing a canonical at a page that redirects or is marked noindex.
