Cravath Swaine is a very old, very established and very rich New York City law firm with hundreds of lawyers. So they are allowed to break the rules and communicate a message to its clients that they need Cravath not that Cravath needs them.
“Cravath has been known as the premier U.S. law firm for nearly two centuries.” So says their website.
Most lawyers and law firms not Cravath
If you don’t consider yourself “the” premier U.S. law firm, then you might need your home-page to communicate a different message – what you can do for your clients. For example, the Cooley law firm has a rotating “spotlight” box front and center on their home-page that touts results its delivered to its clients.
Be Cooley not Cravath
