Good bios are the most important part of a legal website. Period.
85% of all law firm website traffic goes to bios. In fact, the simplest form of a solo website is a well thought out and presented bio.
Bio microsites take the bio to the next level. By featuring a great picture and then presenting everything related to a lawyer within that bio using tabs to delineate different sections, a visitor never has to leave your bio page to get a sense of who you are and what you've done.
People buy from people they trust - and your bio, properly done, is one of the best ways to establish or reinforce that trust.
