THE SHORT ANSWER
Funnel analytics measures how eligible people progress between defined stages and where they stop. It helps locate bottlenecks by segment, but the result depends on stage definitions, identity, time window and the events the system can observe.
Define stages around customer progress
| Stage | Observable signal | Question |
|---|---|---|
| Discovery | Eligible impression or search visibility | Did suitable demand encounter us? |
| Visit | Qualified landing session | Did the promise earn a visit? |
| Engagement | Meaningful product or content action | Did the experience help evaluation? |
| Conversion | Qualified lead or checkout step | Did intent become a committed action? |
| Purchase | Completed, valid order | Did the transaction complete? |
| Repeat | Relevant later value event | Did the experience earn return behaviour? |
Calculate transitions, not only the final rate
For each adjacent stage, divide the people or eligible events reaching the later stage by those reaching the earlier stage under consistent identity and time rules. A weak final conversion rate may be concentrated in one transition rather than spread across the journey.
Open and closed funnels, user and session scope, and required step order answer different questions. Preserve those settings beside the result.

Segment the bottleneck
- New versus returning
- Channel or campaign
- Landing experience
- Device and browser
- Product or category
- Geography or service area
- Offer or promotion
- Cohort and time period
Averages can conceal a payment problem on one device or a low-quality traffic source. Stop splitting when the remaining volume cannot support the apparent precision.
A funnel is a diagnostic model
Customers can skip stages, return later, switch devices, buy offline or take paths the implementation never records. A drop-off can also represent a person deciding correctly that the offer is not suitable.
