Canonical link for joomla

I created a plugin that will allow joomla to specify article canonical link

the plugin will Add <link> tag to the head of the document

<link rel="canonical" href="product.php?item=swedish-fish" />

To specify your canonical link using this plugin. Use the syntax below:

{set_canonical_url value=http://domain.org/your_page.html}

Use this code inside your content.

download the plugin here: canonicalurl.zip
