I am often asked this question. The short answer is yes. The long answer is, "It depends". A few factors determine this listed below in no particular order.
1. Practice Area. Does the average internet user need an Insurance Defense/General Litigation attorney? Most likely not. Internet surfers may however need a lawyer in practice areas of family, divorce, criminal, small business incorporation, construction/home improvement, immigration, real estate, bankruptcy, consumer protection, personal injury, medical malpractice, estate planning etc. You get the picture.
2. Geographical area. For instance, if you are in a very rural part of the country with little internet access, then do not expect to have thousands of web hits per month.
3. Demographics. Younger folks tend to be online more than older folks.
My advice. If you are unsure if your area of practice and geographic situation will result in prospective clients looking for you via the internet, start small. Get a basic website and see what happens.
