Our colleague over in Strategic Communications, Tristan Peery, has shared an informative guide for understanding the importance of reviewing your pages' canonical tags. If you're unfamiliar, the canonical tag is a tool that informs search engines of:

• a preferred URL in case there are multiple URL path references in your site leading to the same content, and/or;
• which site is the original publisher of a page in the case where content is duplicated or very similar from across multiple sites on the web.

In both cases, knowing when and how to set a canonical tag means better search results and avoids SEO penalties that may wind up hiding your content in search indices.
