Inserts canonical link code into header. After activation, from your WordPress Settings, change Permalinks to Custom Structure: /%postname%/ and you’re done, no further steps are needed.
If you have any problems please visit: https://wordpress.org/extend/plugins/canonical-link/installation/ for full detailed instructions.
The importance of the canonical link is to give Google a clean representation of what you want your URLs to look like and how you want Google to index them, this can also help to clear up duplicate page issues.
To verify that the canonical link has been activated properly you will need to use Firefox which I highly recommend anyways ( http://www.mozilla.com/?from=sfx&uid=266924&t=318 ) to check for a “C” to the right of URLs in the URL bar in your browser with this SEO add-on: https://addons.mozilla.org/en-US/firefox/addon/321/.
