Do you give enough importance to your street address on your website as you do to your phone number?
If you were to look around at most law firm’s websites you would be hard-pressed to find their address on the homepage. Rather it is usually buried on their contact page. As much as you may think your physical address is not as relevant as your email address or phone number on your website, it actually plays a large part in announcing to the search engines where your business is located.
Last year Google announced their formal support of microformats (RDFa) and recommendations on how to deploy them. With that as an introduction you can now better understand the idea of placing your street address not only on your homepage, but also make sure it is formatted corrector so that Google and the other search engines honor it. You can create your hCard with no HTML knowledge at microformats.org. Here’s an example of the resulting HTML and what it would look like on the website.
Forward those two links to you webmaster now asking him to promote your street address to your home page. You can still leave it on the contact page, of course.
Now I’m not saying your legal website will rank higher because of this addition. I have not seen it, nor have I heard of anyone out in the wild claiming so. However if you implement best practices for your law firm consistently you may be ahead of the game if the search engines decide to add this as one of their levers.
