# Funnel

## Overview

Funnel measures how users move through a defined series of actions and where they drop off. Use it to quantify conversion rates and time‑to‑convert across onboarding, checkout or any multistep flow.

***

## Common Use Cases

* **Onboarding**: Sign‑up → Email Verify → First Action
* **Ecommerce**: Product View → Add to Cart → Checkout Started → Purchase
* **Marketing**: Ad Clicked → Landing Page View → Sign‑up
* **Upgrade funnel**: Free Trial → Key Feature Used → Paid Plan

## Interface Walkthrough

| Setting                  | Purpose                                                       |
| ------------------------ | ------------------------------------------------------------- |
| **Steps 1 → N**          | Each step is one or more events. Order matters.               |
| **Aggregate By**         | Count *Unique users* or *Unique sessions*.                    |
| **Conversion Window**    | Max time from first to last step (mins / hrs / days).         |
| **Date Range**           | Period in which Step 1 must occur.                            |
| **Measure time between** | Unit for the “average time” stats (seconds, minutes, hours…). |
| **Conversion calc.**     | *Overall* (versus Step 1) or *Step‑by‑step*.                  |
| **Global Filters**       | Narrow the cohort (e.g. Device = Mobile).                     |

## Quick Example (Step Checkout)

1. Steps: ① Product Viewed ② Add to Cart ③ Purchase
2. Aggregate By: *Unique sessions* | Window: *Within 3 days*
3. Date Range: *Last 30 days* | Time between: *hours*
4. Run → Chart shows counts, % drop‑off, and avg hours between steps.

   *Interpretation:* if big churn between Add to Cart and Purchase, improve checkout UX.
