The 4 C's: Captivate, Convince, Convert, Cultivate
The four jobs every website, online store, marketplace and app has to do to win a customer, and keep them. What each C looks like, and where each one leaks.
Most businesses have a website. Many also have a store, a booking app or a members' area. They can look great and still not sell. When I check one, I don't start with the design. I check four jobs, in order. I call them the 4 C's.
Cultivate brings people back to the start: a happy customer returns, and sends their friends.
Each C answers one question the visitor has
| The visitor asks | Its job | |
|---|---|---|
| 1. Captivate | “Is this for me?” | Get attention, and keep it |
| 2. Convince | “Can I trust them?” | Build trust, show the value |
| 3. Convert | “How do I go ahead?” | Make the next step easy |
| 4. Cultivate | “Why come back?” | Turn one sale into a relationship |
The order matters. If you don't captivate, nobody stays long enough to be convinced. If you don't convince, the best button in the world won't be pressed.
And the 4 C's aren't only for websites. The same four jobs show up in everything people buy or book online. Try it below.

Pick what you're building, then tap a C
A local business: a plumber, a play centre, a clinic
The same four jobs, three different products
| Website | Marketplace | App | |
|---|---|---|---|
| Captivate | Service + suburb in the headline | Search results that match | Value before the sign-up |
| Convince | Reviews and real photos | Ratings on both sides | Show it working with sample data |
| Convert | One clear call or book button | Pay safely on the platform | The first result within a minute |
| Cultivate | Thank-you and review request | Paid on time, easy repeat bookings | Useful notifications, visible progress |
A marketplace does every C twice: once for buyers and once for sellers. That's why marketplaces are harder than they look.
Whatever you're building
Do
- Say who it's for in the first screen
- Show proof before you ask for anything
- Give one obvious next step
- Plan what happens after the first sale
Don't
- Open with your company name and a welcome
- Ask for an account, a card or every permission up front
- Offer three buttons that all look the same
- Go quiet once they've paid
Where to start
- 1
Go through it as a stranger
On your phone, from the first screen to the thank-you.
- 2
Write down where you hesitated
Each pause belongs to one of the four C's.
- 3
Fix the first leaky C first
Work in order. Fixing Convert won't help if people leave at Captivate.
- 4
Then plan Cultivate
It's the C most businesses skip, and the one that brings people back.
What I learned
The principle
A good product does four jobs, in order: get attention, earn trust, make it easy, and give a reason to come back. Find the first job that's failing, and start there.
