Example Canonical Tag Generator: before and after

Before
https://example.com/shoes/
https://example.com/a?b=1&c=2
After

<link rel="canonical" href="https://example.com/a?b=1&amp;c=2">

How it works What the Canonical Tag Generator does

Writes a <link rel="canonical"> tag for every URL, with characters escaped for HTML.

Wraps each URL in a <link rel="canonical"> tag, escaping any & in query strings so the HTML is valid. Paste the tags into your page templates or hand them to a developer.

A canonical URL should be absolute and should point to the version you want indexed. Normalise URLs first if your list mixes http and https or www and non-www.

3 steps How to use the Canonical Tag Generator

  2. Check the settings and adjust them to your job — the result updates as you type.
  3. Copy the result and paste it wherever it needs to go. Nothing is uploaded, so client and confidential data stay on your machine.
