How can I prevent our Mobile, AL subdomain from appearing in Suggested Websites?

For our site, we have a domain URL scheme in the form of: city.domain.com. When our visitors search for us in iOS Safari, no matter where they are located, the Suggested Website is mobile.domain.com. This is not our mobile site, but our homepage for Mobile, Alabama, USA, and it is causing problems for our users located in Mobile. We have had this URL scheme since 2005.


How can we prevent the Suggested Website from suggesting the incorrect site?
