There are many SEO companies that throw it all on a big pile.
With this I mean that they make no difference in doing the promotion of a plumber website or website for a landscaping firm. I understand as a professional in this field that there are things they have in common but there are also things completely different.
Comparing apples and pears in SEO
You can not compare apples and pears and to keep it in the fruit section some fruits should not be stored next to each other also. This is the same for SEO.
A plumber website needs to show their work and what they can repair. A lawyer website have to establish trust and respect. There is one big difference already. I am not trying to say that a plumber does not need to be a trusted website, but just that it is a different type of trust level.
On the website of LbL Internet marketing you can read in their product page http://lblinternetmarketing.com/law-firm-seo/ what they can do for you as a law firm to establish more trust and all the other things you need to gain more customers.
Web design for law firms
There is also a difference in web design for law firms that differentiate them from other websites. If you click on the link in the previous sentence you can see what they wrote about that.
The about or bio page should be written a certain way and show who a client is putting his or her trust in. You generally talk about some things in your private life after all that you maybe rather not talk about.
I hope this article have informed you a little more about the subject of SEO and webdesign for law firms and that there is a difference with many other types of firms that need these services.
