-
Step 1: Recognise repeated versions
Filters and tracking links can create several page addresses.
On-screen labels: Main page URL; Tracking version; Filtered version.
-
Step 2: Choose a preferred address
Decide which equivalent version should be the main one.
On-screen labels: Preferred page; Equivalent content; Consistent address.
-
Step 3: A canonical is a signal
Search engines can still choose a different canonical.
On-screen labels: Suggested main URL; Search engine choice; Check the result.
-
Step 4: Keep supporting signals aligned
Internal links and sitemaps should use the preferred URL.
On-screen labels: Internal links; Sitemap entry; Canonical reference.
-
Step 5: Use redirects for actual moves
A canonical reference does not send visitors elsewhere.
On-screen labels: Moved page; Relevant redirect; Visitor destination.
-
Step 6: Inspect important examples
Use Search Console to review the selected canonical.
On-screen labels: Preferred URL; Google-selected URL; Resolve mismatches.
A practical check for your business
List the alternative URLs and identify the intended main version before changing canonical references. Check that the chosen destination works and represents the same content. A canonical reference does not itself send a visitor to another URL.
