title: SEO and Subdomains (Rails Apps)
body: <p>Let's say I have the following subdomain to my root (mydomain.com): blog.mydomain.com.</p>
  
  <p>Does Google treat the subdomain separately from the root from an SEO perspective?  </p>
  
  <p>Is it better to use mydomain.com/blog so that I'm optimizing my root page?</p>
  
  <p>Is there an best-practice RoR approach to rectifying sub-optimization issues presented by the use of subdomains?</p>
