Exact Match Domain or Near Exact Match Domain. This is where your keyword is the name of your website, as is the case with lawfirmseo.us. You can also have a near exact match like with GoldIRACustodians.com, which is built to rank primarily for Gold IRA. You get advantages to ranking for your keyword by having your name in your title, and you have to be extra careful not to over optimize.
