Angie's List is worthwhile only if you can maintain customer satisfaction at a consistantly high level. One unhappy customer can trash your reputation. I would say that the A-List provides 70~80% of my business at this point. I'm a very small operation and I don't even try other forms of advertising, I don't need to.
It takes time and effort to build a list of satisfied customers but once you do it really helps to attract new business. The A-List tells me that they have 40,000 members in the Pittsburgh market and when any of those members need tree service I come up at the top of the list. This Winter, for the first time, I've been busy and working the whole time.d out
Angie's List members pay a monthly fee to be able to read reviews of any type of contractor they might hire. Universally the members tell me that the contractors they have hired through the A-List have met or exceeded their expectations. The scammers and fly-by-nights are quickly filtered out by the members and they find that worth the money. When I show up for an evaluation the customer has already read my reviews and that gives me credibility from the get go.
I honestly don't think many of you could do well if your customers could read what your other customers think of you.
