How we count: a business is listed when its website was first seen 30 to 120 days ago, it is in the US, and it shows a real business. We leave out personal sites and sensitive categories such as health care. We show the name, the website, the city and a description we write. We never show emails, phone numbers or people's names on this page. Full method.
