Canonical Tag Generator

Generate a rel=canonical link tag to prevent duplicate content.

Tag (paste into <head>)
<link rel="canonical" href="https://example.com/blog/my-post" />

Why canonical tags matter

When the same content is reachable at multiple URLs — with tracking parameters, trailing slashes, http vs https, or print versions — search engines can treat them as duplicates and split your ranking signals. The rel="canonical" tag names the single preferred URL so all that authority consolidates. Always use an absolute URL, place the tag in the page's <head>, and have each variant point to the same canonical. Generated locally in your browser.
