Frequently Asked Questions

A canonical tag (<link rel="canonical" href="...">) tells search engines which URL is the authoritative/preferred version of a page when multiple URLs serve similar or identical content. It was introduced by Google, Bing, and Yahoo in 2009 and is the standard solution for managing duplicate content without redirects.

Use a 301 redirect when the old URL should no longer be accessible at all — it sends users and bots directly to the new URL. Use a canonical tag when both URLs should remain accessible (e.g., URL with tracking parameters) but you want to tell search engines which one is the "real" version for indexing purposes.

Yes. Adding a self-referencing canonical to every page is a best practice. It explicitly signals the preferred URL (including http vs https, www vs non-www, trailing slash or not) and prevents problems if scrapers republish your content — Google can still identify your URL as the original.

Google treats canonical tags as hints, not directives. If the specified canonical URL has significantly different content, is not crawlable, or is part of an inconsistent signal cluster, Google may override it and choose a different canonical. Consistent canonical signals (canonical tag + sitemap inclusion + internal linking + 301s) ensure Google respects your preferred URL.

How It Works

Enter the Preferred URL

Enter the canonical URL — the exact version of the page you want indexed, including protocol, www/non-www, and trailing slash preference.

Configure Options

Enable AMP canonical or paginated page options for special cases. The output updates to include all necessary link tags automatically.

Add to <head>

Copy the tag and place it inside the <head> of each page. For bulk generation, paste multiple URLs and copy all tags at once.

Common Use Cases

UTM Parameter URLs

Pages accessed via UTM tracking URLs (e.g., ?utm_source=email) should have canonical tags pointing to the clean URL to avoid duplicate content issues.

Filtered & Sorted Pages

E-commerce category pages with sort/filter parameters (?color=red, ?sort=price) should canonicalize to the base category URL.

Print-Friendly Pages

Print versions of pages (e.g., /page?print=1) should canonicalize back to the standard page URL to consolidate ranking signals.

AMP Pages

AMP versions of articles must include a canonical tag pointing to the canonical (non-AMP) URL, while the canonical page should link to the AMP page with <link rel="amphtml">.

Paginated Content

For paginated series (page-1, page-2, page-3…), consider having page 2+ canonicalize to page 1 or use self-referencing canonicals per Google's current guidance.

HTTP to HTTPS Migration

During migration, use canonical tags on HTTP pages pointing to HTTPS equivalents as an additional signal alongside 301 redirects.
