This plugin lets you modify or set the meta tags of the canonical URL and meta keywords in the Quick Edit interface of each post or page.
Why do I need to set the canonical URL? 
If you use a subdomain and point it to specific pages / posts then WordPress automatically sets the canonical URL to the main domain (usually www.), but for SEO and indexing reasons you may want to set the canonical URL to the subdomain instead.
Why do I need to set Meta Keywords? 
It helps Search Engines to index your content better, especially when you have important content which is generated automatically on the page and is not part of the HTML.
