Canonical URL Generator
Generate canonical link tags to prevent duplicate content
Canonical URL Generator normalizes a URL (resolving it to a proper absolute address) and produces the exact <link rel="canonical"> tag to paste into a page's head, so search engines know which version of a page to treat as the real one when several addresses could reach it.

- 2
Click "Generate" to normalize it into a proper absolute address.

Everything you need to know about canonical URLs
What does a canonical tag do?
A canonical tag tells search engines which URL is the "real" one to index, when the same or very similar content is reachable at more than one address — common with URL parameters, http vs. https, www vs. non-www, or duplicate content across categories.
When you actually need this
- Product pages reachable via multiple URLs (different filter/sort parameters showing the same items).
- Content syndicated elsewhere, pointing back to the original as the canonical source.
- Preventing duplicate-content dilution across near-identical pages.
Get it right — a wrong canonical actively hurts
A canonical tag pointing at the wrong URL tells search engines to ignore the page you're trying to rank in favor of a different one — double-check it points at the actual intended page, not a stale or unrelated URL left over from a template.

Frequently Asked Questions
Why does a page need a canonical tag at all?
The same page is often reachable through several addresses — with or without www, with a trailing slash, or with tracking parameters attached. Without a canonical tag, search engines can treat these as separate duplicate pages and split ranking signals between them.
Should a page ever point its canonical at a different page?
Usually a page should canonicalize to itself. Pointing it elsewhere is for genuine duplicates, like a printer-friendly version that should defer to the main article.
Is a canonical tag a strict instruction to search engines?
It's treated as a strong hint, not an absolute command — search engines usually follow it, but may choose differently if other signals (like internal links) disagree with it.
