Lead generation is the work of getting people who might buy from you to identify themselves — by calling, filling in a form, booking a slot or replying. A lead is a person who has raised their hand. Everything else is traffic.
The two kinds, which get confused constantly
| Inbound | Outbound | |
|---|---|---|
| How it works | People looking for you find you | You contact people who were not looking |
| Examples | Search, referrals, your website | Cold email, cold calling, door knocking |
| Lead quality | Higher — they have a need now | Lower — you created the moment |
| Cost shape | Builds an asset over time | Ongoing effort, stops when you stop |
| Speed | Slower to build, compounds | Immediate, does not compound |
What actually counts as a lead
Define this before anyone reports numbers to you. A form fill from someone comparing five suppliers and a phone call from someone ready to book are both “leads” and are not remotely the same thing. Businesses regularly celebrate rising lead counts while revenue stays flat, because the definition quietly loosened.
Where small business leads actually come from
- Search — people actively looking; the highest-intent source there is
- Google Business Profile — for local businesses, often the single largest source, and free
- Referrals — highest close rate, lowest cost, hardest to scale on demand
- Paid advertising — immediate and controllable; stops when payment stops
- Email to people who already know you — consistently underused
The arithmetic that makes it manageable
Customer value multiplied by close rate gives you what a lead is worth. If a customer is worth $3,000 and you close one in four, a lead is worth $750 and spending $150 to get one is excellent. Without those figures, every cost per lead looks either alarming or arbitrary.
Buying leads
You can buy leads from marketplaces. They are usually sold to several businesses at once, so speed of response decides who wins, and you keep nothing when you stop paying. It can make sense if you need volume immediately and respond within minutes. It is a rental, not an asset.
The most common failure
Not the lead source — the follow-up. Enquiries arriving and nobody responding fast enough is the largest leak in most small businesses, and it costs nothing to fix.
