What is happening in Local Search?

There are many businesses that are benefiting from their website being listed in the local searches for a certain city and service.  Here are some examples of sites like storage bend, burbank salon, los angeles plumbing, bend hair salon, los angeles carpet cleaning, bend crane, bend truck repair, los angeles water heaters, bend garage doors, beaverton auto body and of course there are many more.  What these companies have chosen to do is have a domain name for their business location and service or instead of just focusing on their business name.  There have been more and more businesses doing that over the last few years which seems to be a smart marketing move as the Internet gets more and more complex and competitive.  Actually doing this for a company requires advanced skills in marketing thought.  Most businesses don't do this because it just doesn't make sense to some of them, however, the ones that do will benefit from limited supply of specialty domain names that are only available one time.
