What Are Leads in Business? A Plain Definition With Examples

A lead is the first sign that someone might buy from you, and in a small service business it usually arrives as a call, a text, a form or a referral that someone has to answer.

A lead is a person or business that has shown interest in buying from you and has given you a way to reach them, such as a phone call, a text, a website form, a booking request or a name passed along by a current customer. A lead becomes a customer only after someone follows up and the person books or buys, so a business with plenty of leads and slow follow-up can still have an empty calendar.

In a salon, a lead might be a missed call from a new number on a Tuesday afternoon; in a plumbing company, a quote request through a website form; in a dental office, a parent asking through the Google listing whether the practice takes their insurance. Each one has a name or number attached and a reason to reach out, and each one is worth the most in the first hour after it arrives.

The terms owners hear most, in plain words

A five-step routine for every lead

  1. Answer within the hour by phone, text or message, using whichever channel the lead used.
  2. Ask two questions that show whether the lead is qualified, such as what they need and when.
  3. Offer a specific time or a price range in the same conversation, rather than "let us know."
  4. Follow up twice if they go quiet, once the next day and once a few days later.
  5. Write down the source of every lead and whether it booked, so you know which sources to keep paying for.

Why it works

The first step in that routine is also the best measured. In a study published in Harvard Business Review, firms that tried to reach a new inquiry within an hour were nearly seven times as likely to qualify the lead as firms that waited an hour longer, and an audit of 2,241 U.S. companies in the same article found that 23% never answered a new web inquiry at all.
