How to use
How to Generate a Canonical Tag
Creating a canonical link tag takes 3 steps:
1
Enter the primary page URL
Type or paste the full URL of the canonical version — the page you want Google to index and rank. Always use the HTTPS version with or without www, whichever is your preferred format.
2
Click Generate
The tool instantly creates the HTML link tag in the correct format for the HTML head section.
3
Copy and paste into your HTML head
Copy the generated tag and add it inside the <head> section of every page that shares the same content — including the canonical page itself (self-referencing canonical).
📄 Example scenario:
Your page exists at both:
• https://example.com/page
• https://example.com/page?ref=ads
• https://example.com/page?utm_source=newsletter
Enter https://example.com/page and add this tag to all three versions:
Add the canonical tag to every duplicate page pointing to the primary URL — and also add a self-referencing canonical to the primary page itself. Google recommends self-referencing canonicals on all pages to reduce ambiguity about preferred URLs.
When to use it
When Do You Need a Canonical Tag?
Use a canonical link tag whenever the same or similar content is accessible at more than one URL:
🔗 HTTP vs HTTPS — if your site is accessible at both http:// and https://, canonical the HTTPS version
🌐 www vs non-www — if yoursite.com and www.yoursite.com both resolve, canonical your preferred version
📈 URL parameters — tracking parameters like ?utm_source= or filter parameters create duplicate URLs for the same content
📄 Paginated pages — page 1, page 2 of the same article or product listing may need canonicals pointing to the main page
🛒 E-commerce filters — product listing pages filtered by colour, size, or price often create duplicate content
📋 Syndicated content — if your article is republished elsewhere, the publisher should add a canonical pointing back to your original
About
What is a Canonical Tag?
A canonical tag — formally known as a canonical link element — is an HTML meta tag that specifies the preferred URL for a web page. It is placed in the HTML head section and tells search engines like Google which version of a page should be indexed and ranked when multiple URLs serve identical or very similar content.
Without canonical tags, Google may split ranking signals (such as backlinks and authority) across multiple duplicate URLs instead of consolidating them on your preferred page. This dilutes your SEO and can result in lower rankings across all versions. Use this canonical tag generator — also called a rel=canonical generator or canonical URL generator — to fix duplicate content issues and strengthen your page authority.

A canonical tag is an HTML element that tells search engines which version of a page is the primary or preferred version. It is placed in the HTML head section and prevents duplicate content penalties when the same content is accessible at multiple URLs.
Use canonical tags when the same content is accessible at multiple URLs — such as HTTP and HTTPS versions, www and non-www, pages with tracking parameters, paginated content, and e-commerce filter pages.
Yes. Canonical tags consolidate ranking signals from duplicate pages to the canonical URL. This prevents Google from splitting page authority across multiple URLs and helps the preferred page rank higher.
A self-referencing canonical points to the page itself. Google recommends adding them to every page — even those without duplicates — to clearly signal the preferred URL format (with or without www, trailing slash, etc.).
