Bingo! We have two computer shops in our town. I'm one of them. The other one will probably be run out of town. They've tried Angie's List, Yelp, Google +, Facebook Marketing, Adwords, .....

It hasn't done anything for them. People will find out about your reputation anyways.

As Bob Dylan would say, "You don't need a weatherman to know where the wind's blowing!"

Just do well, and people will spread the word through other means (Google is what matters, it seems).
