There’s a wide variety of domain name extensions out there that lawyers might want to consider. The best is obviously .com the dominant extension. If you are trying to pick a nice keyword rich domain like memphisbankruptcylawyer.com or atlantapersonalinjury it’s going to be taken. While you can think up non-taken permutations speaking from experience they don’t work as well.
Lots of lawyers like to use their own name but the URL is an important ranking factor especially in bing/yahoo which accounts for about 30% of the search market. A shorter URL will also typically get better pay per click results.
There are now a large number of domain extensions available. For search engine optimization purposes Google does not prefer one domain over another except as to geotargeting. Two letter extensions are reserved for particular countries like .us, .cn, .co. These extensions cannot be geotargeted except to their countries of origin. There are exceptions to this where countries with snappy marketable extensions have opted to develop their extension as a globally available extension. Search engines seem to have unlocked the geotargeting from these domains. Columbia has dedicated it’s .co since it sounded a lot like company and looked kinda like .com and has burned a bunch of money advertising it.
I not a big fan of .co for the reason that confusion with .com seems very natural to this extension. The biggest downside to using non .coms is a potential security risk of people thinking an email address is a .com and misdirecting email and while I think it’s overblown except for larger companies .co particularly suited to this downside. To minimize this and prevent confusion you can reserve a name based .com like sandylawoffice.com and use that for email. You don’t have to put up a site on a domain name to use the email address. Larger companies will buy all extensions of their site to prevent spoofing attacks where people use official looking emails to try to get personal info.
Since search engines treat domains equally and quite frankly the recognition difference between other domains is minimal, it comes down to what’s more catchy and memorable. The top choices for me are .me and .pro . .Me is the unlocked country code for Montenegro and widely available. .Pro is a registry launched originally in 2006 and limited to licensed professional with a very high registration fee. It’s still suppose to be limited for professionals and the registration fee has dropped to be competitive levels. It’s not widely available at registrars and the best I’ve found is Encirca.
I hope the above is helpful and expands your attorney internet marketing horizon.
