Funnel Analysis

A method of tracking user progression through a defined sequence of steps — from awareness to conversion — to identify where users drop off.

What is Funnel Analysis?

Funnel analysis tracks how users move through a defined sequence of steps toward a goal (signup, activation, purchase). At each step, some users drop off — the funnel shape visualises where the losses occur.

Reading a funnel

`

Visited landing page: 10,000

↓ 4.2% conversion

Signed up: 420

↓ 48% conversion

Completed onboarding: 202

↓ 31% conversion

Activated (key action): 63

↓ 22% conversion

Upgraded to paid: 14

`

The biggest absolute drop (10,000 → 420) is the landing page. The most improvable step is often activation (48%) — improving it by 20% compounds through every step below it.


How to prioritise funnel optimisation

Focus on the step with the highest traffic × lowest conversion rate. Small improvements at high-traffic steps have outsized downstream impact.

Frequently asked questions

Should I optimise the top or bottom of the funnel first?

Bottom of the funnel first — activation and conversion improvements have immediate revenue impact. Top-of-funnel improvements bring more users into a broken funnel, amplifying churn. Fix the leaks before turning on the tap.

How do I know which funnel step to fix first?

Calculate the revenue impact of a 10% improvement at each step. The step where a 10% improvement generates the most incremental revenue is your highest leverage point.
