A lead funnel is a multi-step flow that turns a click into a qualified contact by breaking one big ask into a sequence of small ones. Where a landing page makes its whole ask at once, a funnel spreads it across several screens, each requiring a single tap, and captures the email or phone near the end - as the delivery mechanism for a result the visitor now wants.
The mechanism is commitment momentum: answering an easy first question costs nothing and creates investment, so completion of the capture screen rises sharply. The quiz funnel is the highest-performing variant, because it reframes lead capture as a service - the visitor is getting a personalised answer, not filling in a form. Qualification happens during capture, so every answer can feed lead scoring and the contact arrives pre-segmented.
Funnels win on cold and warm paid traffic where attention is bought and qualification is the bottleneck; for high-intent visitors, a short form is better. The funnels guide covers anatomy, scoring, tracking, and compliance for lead funnels.
