The conversion funnel explained simply (+ tutorial)

The "conversion funnel" describes the journey from a stranger to a customer. Understanding it means you stop losing prospects along the way. Here's the simple explanation, with a tutorial to optimise yours.

The 3 main stages

The funnel is classically split into three levels:

• TOFU (top) — Top of Funnel: discovery. The audience doesn't know you yet.
• MOFU (middle) — Middle of Funnel: consideration. They're comparing you.
• BOFU (bottom) — Bottom of Funnel: decision. They're ready to buy.

Each stage corresponds to a mindset and a fitting type of content.

Stage	Mindset	Fitting content
TOFU	"I have a problem"	Blog articles, videos, social media
MOFU	"What solutions are there?"	Comparisons, case studies, guides
BOFU	"Which one do I choose?"	Demo, quote, testimonials, guarantee

Why your funnel "leaks"

At each stage you lose people — that's normal. The goal is to reduce the leaks. Common causes:

• TOFU: you're not attracting the right audience.
• MOFU: you're not addressing objections.
• BOFU: friction (a long form, a hidden price, a lack of reassurance).

Tutorial: mapping and optimising your funnel

Step 1 — Draw the journey

From "first visit" to "customer", list every actual stage (homepage → article → service page → contact).

Step 2 — Measure each transition

How many move from one stage to the next? That's where the leaks hide.

Step 3 — Identify the biggest leak

Focus on the stage where you lose the most people — that's your biggest lever.

Step 4 — Form a hypothesis

"If I cut the form down to 3 fields, more people will take action."

Step 5 — Test one thing

Change a single element, measure, compare. Then start again on the next leak.

A concrete example

A site gets 1,000 visitors/month. 100 visit the service page (10%), 10 fill in the form (10%), 3 sign (30%). By raising the form from 6% to 12% conversion, you double sales without more traffic.

Automation in service of the funnel

AI can feed each stage: automatic follow-ups in MOFU, instant responses in BOFU, lead qualification. The funnel never sleeps. (See our AI agents.)

Conclusion

An optimised funnel means more customers with the same traffic. Start by measuring, spot the biggest leak, and plug it. Need an outside perspective? Let's talk.

Do you need a complicated tool? No, simple audience measurement is enough to get started.

How many stages should a good funnel have? As few as possible. Every extra stage is a potential leak.
