I want to start a small business that offers directories for niche products and services based on cities. (Yes I know, a lot of people are doing this already)
These niche companies hopefully will pay me a minimal fee to list them in my directory (contingent on getting place high in the SERPS)
I am thinking of doing this two ways: 1. Purchase individual domains, or 2. Use sub-domains based on the city.
Structure 1: Denver-widget-directory.com, Miami-widget-directory.com, etc.
Structure 2: Denver.widget-directory.com, Miami.widget-directory.com, etc.
Of course structure 2 is a lot cheaper, but does it have drawbacks?
I am new at this so all comments welcome!
