Why this matters
Canonical tags help avoid duplicate content issues by consolidating signals to a main category URL, improving its ranking potential.
Hypothetical standard operating procedure
Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.
- Identify category page URL for each faceted URL.
- Add <link rel="canonical" href="category-page-URL"/> tag in the <head> of faceted pages.
- Or send a canonical Link HTTP header for facets.
- Check internal links don't overly point to faceted URLs.
- Monitor Search Console for reduction in duplicate URL indexing.
Watch for
Google may ignore canonical tags if pages differ significantly or if internal links point heavily to faceted URLs, limiting effectiveness.
Definition of done
Filtered URLs have canonical tags pointing to the main category URL confirmed by HTML headers or page source.
