Google has added a new feature in the Google sitemap program under webmaster tools, and it is a nifty link tool. Google has always offered some kind of an idea of the # of links pointing to your site, but its always been a very low # and not a true indicator of the total # of links pointing to your site.
This new tool offers a much better indication of how many other sites are linking to your site, the different pages that are being linked to and also the internal links from within your own site. This is a very valuable free tool and can provide a lot of great insight into who is linking to your website.
Your lawfirm should make sure that its website is included in the Google sitemap program. It can offer a lot of very valuable information and is a good way to make sure that Google indexes all of the pages within your site.
