Joomla 3 canonicals are often incorrectly generated, and Joomla 2.5 does not output canonical links at all, which can result in many duplicate pages for your content. Other extensions solved this problem only partially or incorrectly. We applied our long experience with Joomla to create Canonical Links All in One, a comprehensive solution to rule them all!

If you change alias of an article, or if you can reach it in many ways, we've got you covered, Google won't penalize you.

With full support for native content and K2/VM 3/EasyBlog 5 pages, we also set canonicals for paginated series, so that Google can index properly your categories with more than one page.

You can also choose to automatically redirect users to your canonical page. We tweaked our plugin so that the most appropriate link is chosen, based on the structure of your menus.

If your website can be accessed with multiple domain names, you can set your preferred domain for the canonical links in options.

And if you need special tweaks for some pages, you can also override automatically generated canonical links for specific pages, or completely remove canonical links from them!
