Welcome to the Q&A Forum

Thanks for the quick response.  If that is the case why is there a sub-domain option?  Is it only to have the ability to see linking domains and links?  Not to have the ability to see authority?  I then typically default to page authority to have a sense of the authority of the sub-domain.

I don't know the answer to your question but can share my personal experience. I have waited as long as 10 months for old, redirected pages to be removed from Google's index.

Thanks Martijn, I figured the domain name doesn't needed to be included, but just wanted to be sure for Universal Analytics. Thanks, Brian

This sounds like a problem for your internal IT to solve. It sounds like that URL is in your 301 redirect and it's quite possible it's used for tracking purposes. I would find out what it's used for first. From an SEO standpoint, I would simply canonical your home page to www.crh.org/mobile and that will avoid any duplicate content issues.

Hi Simon, thanks for the help and noticing that!  We actually noticed there were 302 redirects causing issues which we removed on February 5th, so you're right, Google probably hasn't cached the updated version of our site..hopefully!
