Most law firms and professional service firms market to prospects in their local area. Doing so on the Internet is not that difficult. Yaro Starak, c/o of Will Swayne, has nice post about marketing your local business on the Internet.
Highlights include:
- People search for products and services in their local area, [industry name] + [location]. Architect and perform SEO work for your blog or website accordingly.
- Clearly identify your local area so that local visitors know they’ve come to the right place.
- Pay-per-click (PPC) advertising, particularly Google Adwords, can be an excellent buy when local specific.
Haven't seen as much from Yano's blog recently, but Small Business Branding is a good one to add to your feeds.
