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 conversion rate.
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.
