Hi, i am in the process of setting up a business directory site that will be used in a number of cities, though i am initially launching with only one city. My question is, what is the best URL structure to use for the site and should i start using this URL structure from day one? At the moment i am using www.mysite.com.au as my primary website where it contains all listings for the the one initial launch city. Though to plan for the future i was considering this URL structure: www.mysite.com.au/cityname so for example, if i launch in the city Sydney initially then all website traffic that goes to www.mysite.com.au would simply be redirected (302 temp redirect?) to www.mysite.com.au/sydney. When i expand to other cities www.mysite.com.au would simply be a "select your city" screen that then redirects to the city of choice (similar to www.groupon.com page). How would doing a 302 redirect from www.mysite.com.au to www.mysite.com.au/city impact on SEO for the initial launch? Or should i just place this on the root domain since no other cities exist at the moment?
