Directory listings like Google maps, Yelp and Bing rely heavily on your physical location.

It is extremely difficult, and in a majority of cases, impossible to be found in a neighboring city’s local listing. It is possible to show up in another local search if you don’t have much local competition, but practices that are actually in that city will ALWAYS show up first.

Think about it this way - If you were searching for a local coffee shop, you wouldn't want to get back results from the next town over.
