Over at the [Non]billable Hour blawg (law blog) Matt Homann has assembled a fascinating group of posts on how lawyers should -- and should not -- market to women as potential clients. Part of his Five by Five series, featuring five insights each by five guest bloggers, it can be found starting here.The Five by Five was contributed by some of the finest, sharpest women blogging professionals around. I was honored to be invited to contribute along with this distinguished group. Check it out -- the marketing advice is geared toward lawyers, but most points apply to just about any professional services business.Perhaps one of the most intriguing aspects to the post is what it demonstrates about changes in the practice of law in the United States.Not so long ago -- well within my lifetime -- lawyers were prohibited from advertising. Marketing was frowned upon, lest it somehow be confused with ambulance chasing. There were strict guidelines on what lawyers could say about themselves, their experience and their practices. All that's changed, of course. The ban against advertising long ago bit the dust. The largest law firms now routinely hire Marketing Directors. And savvy innovative lawyers, like Matt, are paying attention to how to market their services. But as a whole, the legal profession has a lot of catching up to do, and that just may spell opportunity for enterprising marketing professionals.
