Funnel(Funnel)

A model that visualizes prospects narrowing through stages — awareness, interest, consideration, purchase, retention — as a funnel. AIDA, AARRR (“pirate metrics”), and the B2B MQL / SQL pipeline are common variants.

Measuring stage-to-stage conversion and drop-off causes shows where investment will most lift end-to-end yield. Critics argue funnels under-weight post-purchase experience and referrals, prompting the shift toward loop-shaped flywheel models in many modern playbooks.
