Paste any URL to get a clean, correct rel=canonical tag. We strip tracking parameters, enforce HTTPS, and hand you the HTML tag and HTTP header, ready to copy.
Your canonical tag
Canonical mistakes can quietly bury good pages. Our team audits and fixes them across your whole site.
Book a Free Call<head> (one canonical per page).A canonical URL is the version of a page you want search engines to treat as the “official” one
when the same or similar content is reachable at more than one address, for example with tracking
parameters, uppercase letters, or a trailing slash. The rel="canonical" tag points
every duplicate back to that single URL, so ranking signals aren't split across copies.
Without a canonical, search engines may index the wrong version of a page, split your link equity across duplicates, or waste crawl budget. A clean, self-referencing canonical keeps your signals consolidated on one URL, a small tag that prevents a surprising amount of SEO headaches.
It's the version of a page you want search engines to treat as the main one when the same content is available at several URLs.

Yes, a self-referencing canonical is best practice. It removes ambiguity even when there are no obvious duplicates.
Yes. Cross-domain canonicals are valid, for example when you republish the same article on another site.
No. It's a strong hint, not a command. Google usually respects it but can choose a different canonical if other signals conflict.
Use the HTML <link> tag for normal web pages. Use the HTTP header for non-HTML files like PDFs, where you can't add a <head>.
