Canonical Tag vs Redirect: When to Use Each

Canonical tags and redirects both deal with URL signals, but they are not interchangeable. A redirect sends users and crawlers to another URL. A canonical tag keeps the page accessible while suggesting which URL should be treated as the main version.

Use the Canonical Tag Generator when a page should remain accessible but point search engines to a preferred URL. Use a redirect when the old URL should no longer be used.

Use a canonical tag when

The content is very similar, both URLs need to remain reachable, or filters and tracking parameters create alternate versions. Canonical is a hint, so the page should still make sense.

Use a redirect when

The page moved, the old URL is obsolete, or users should never land on the duplicate. Redirects are stronger and clearer when one URL replaces another.

Common mistake

Do not use canonical tags to hide poor site structure. If the duplicate should not exist for users, redirect it. If it must exist, canonical can help consolidate signals.
