Funnel describes the stages users move through on their way to completing a goal. In e-commerce, funnels typically map the path from browsing to purchase. Each stage filters out some users, creating the characteristic funnel shape.
What is a Funnel?
A funnel breaks down the user journey into distinct stages. Each stage represents an action users must take to move forward. Not everyone who enters the funnel reaches the end.
Typical e-commerce funnel stages:
- Homepage or landing page visit
- Category or search browse
- Product page view
- Add to cart
- Checkout start
- Purchase complete
The funnel narrows at each stage because some users leave. The percentage of users moving from one stage to the next is the stage .
Types of Funnels
Conversion funnel: Tracks the path to purchase or signup. Measures how many visitors complete each step.
Checkout funnel: A subset focused specifically on the checkout process. Starts at cart and ends at order confirmation.
Marketing funnel: Broader view including awareness and consideration stages before users reach your site.
AARRR funnel (Pirate Metrics): Acquisition, Activation, Retention, Referral, Revenue. Common in SaaS and product-led companies.
How to Read Funnel Data
Funnel analysis shows where users drop off. Large drops at specific stages indicate problems.
Example funnel:
- 10,000 product views
- 1,000 add to cart (10% view-to-cart)
- 400 checkout starts (40% cart-to-checkout)
- 200 purchases (50% checkout completion)
This funnel shows view-to-cart needs attention. Only 10% of product viewers add items to cart.
Funnel Metrics
: Percentage of users who leave at each stage. High drop-off signals friction.
Stage conversion rate: Percentage moving from one stage to the next. Compare against your own historical data.
Overall conversion rate: End-to-end completion. Product views to purchase in the example above is 2%.
Common Mistakes
-
Too many stages: Keep funnels focused. 5-7 stages maximum.
-
Missing mobile view: Mobile funnels often differ significantly from desktop.
-
Ignoring traffic source: Different traffic sources produce different funnel shapes. Segment your analysis.
