I spend a ton of time working on SEO aspects of sites I work on. I’m also a pre-release team member over at vBSEO, a 3rd party SEO software add-on for vBulletin forums. Today, I question why I do this.
The ‘big daddy’ Google can’t even seem to get their sub domains correct.
all go to the same place.
Both the maps and mail sub domains should 301 re-direct to regular www.
This is an epic duplicate content failure on all accounts. It is possibly the greatest oxy-morons of all time. No one “searches” for Google (ok, maybe a few random’s go to Yahoo.com and search for “google” to get there…), so they seem exempt from anything relating to SEO. Yet, their algorithms penalize websites with duplicate access points.
This is not a difficult ‘final tweak’ either. This is an entry level SEO consideration. Moreover, it can have negative effects on the application itself, such as cookies hitting mix-matched domains.
