What Is Lead?

Sales

Updated 18 September 2026

Quick Answer

A lead is a potential customer who has shown interest in your business and shared contact details — a form submission, a call, or an enquiry — as opposed to an anonymous visitor who hasn't engaged.

Lead vs. Visitor — What's the Difference?

Why It Matters

  • A lead is something you can actually follow up with — a visitor who leaves anonymously is a missed opportunity you can't recover.
  • Tracking how many leads you generate, not just visitors, tells you whether your site is actually doing its job.

How It Works

  1. A visitor takes an action that shares their contact details — filling a form, calling, or messaging.
  2. That contact is now a lead — someone you can follow up with directly.
  3. Not all leads are equally ready to buy — some need nurturing before they convert.

Key Takeaways

  • A lead has shared contact details and shown interest — an anonymous visitor hasn't.
  • Leads matter because they're the only visitors you can actually follow up with.
  • Fast follow-up meaningfully improves conversion from lead to customer.

Frequently Asked Questions

What counts as a lead?

Anyone who's shared contact details and shown genuine interest — not just anyone who visited your website.

How is a lead different from a customer?

A lead has shown interest but hasn't necessarily paid yet; a customer has completed a purchase.

What should I do with a new lead?

Follow up promptly — response speed strongly affects whether a lead actually converts into a customer.
