Conversion Funnel
A Conversion Funnel is a step-by-step map of how people move from first interaction to a desired action such as a purchase, signup, or demo request. It shows each stage, the % of users who advance, and where they drop off.
Common funnels:
E-commerce: Landing → Product Page → Add to Cart → Checkout Steps → Purchase
SaaS: Visit → Signup → Onboarding → Activation → Subscription
Lead Gen/Services: Visit → Offer/Content → Form → MQL/SQL → Consultation/Close
Teams use funnels to diagnose friction, prioritize fixes, forecast revenue, and align marketing + product + sales.
Why It Matters
Find drop-offs fast: Pinpoint which step loses the most users.
Lift revenue efficiently: Improving one critical step often beats adding more traffic.
Budget with confidence: See which channels fill the funnel with high-quality visitors.
Shared language: Product, marketing, and sales work from the same view of the journey.
Examples
Retail: 10,000 product views → 2,500 add-to-carts → 1,600 checkout starts → 1,200 purchases.
SaaS: 5,000 visits → 400 signups → 220 activated → 90 paid.
B2B: 3,000 visits → 180 content leads → 60 MQLs → 25 SQLs → 8 deals.
Best Practices
Define the goal + micro-conversions (e.g., add-to-cart, add_shipping_info, add_payment_info).
Instrument clean events (GA4 recommended events for web/app; CRM stages for B2B).
Segment everything: device, source/medium, geography, new vs returning, cohorts.
Fix the biggest leak first (highest volume × highest drop-off).
Remove friction: faster pages, clearer copy, simpler forms, trustworthy UI, flexible payments.
Match intent to stage: awareness content → mid-funnel proof → decision CTAs.
Test systematically: A/B test offers, CTAs, layout, form fields, and checkout steps.
Measure full-funnel KPIs: step conversion rates, time-to-convert, assisted conversions, LTV/CAC impact.

FAQs
Q1. Is a conversion funnel linear?
Not always. Users bounce between channels and stages. The funnel is a useful model; behavior can be non-linear.
Q2. Funnel vs. pipeline: what’s the difference?
A funnel maps user behavior to a goal (marketing/product). A pipeline maps sales stages from lead to closed-won (sales).
Q3. How do I build a funnel in GA4?
Use Explorations → Funnel exploration (define ordered steps like product_view → add_to_cart → begin_checkout → purchase) and break down by device or source.
Q4. Which step should I optimize first?
Target the largest leak that also has high traffic, so improvements drive outsized impact.
Q5. What metrics matter most?
Step-to-step conversion, abandonment rates, time between steps, assisted conversions, and revenue per visitor/customer.
