Family and Friends are Advocates. Your brother- in-law mentions your business to a colleague over lunch. Your college roommate shares your website in a group chat. These small moments of word- of-mouth can be among the most powerful marketing tools available to you—and they cost nothing. Give the people closest to you business cards, flyers, and anything else they might need to carry your message into their daily lives, into their offices, their neighborhoods, their social circles. Every conversation they have is a potential introduction to a customer who might never have found you otherwise.
