I ran into an interesting website, www.yelp.com. This site is a local business directory with a twist. It allows visitors to rate 1 out of 5 stars for businesses in their local area. And oddly enough, there are a lot of lawyer and law firm listings. I recommend in getting a free listing for your law firm in this site. You can put in basic information including your website. Yelp has a Google page rank of 7 (out of 10) which is pretty high (Yahoo has a page rank of 9)which means it may help your firm website to be listed for SEO's sake.
I would also invite friends and family to give a review of your law firm. I'm not sure what ethical issues this may cause, so check with your Bar Association rules.
Creating your listing on Yelp is not the most important thing you can do to promote you website, but it can't hurt either. If you have 5 minutes, it might be worth the time.
