Marketing funnel
Short definition
The marketing funnel describes the stages a person moves through from first noticing a brand to buying from it.
It is usually split into four stages: awareness, interest, consideration and purchase, and each stage calls for a different kind of message. At the awareness stage a brand is simply trying to be noticed; at the purchase stage a clear offer and an easy checkout step matter most.
How many people move from one stage to the next is measured at every point; a stage with a heavy drop-off shows where marketing effort needs to go. A page that gets plenty of clicks but few form submissions, for instance, points to a problem at the consideration stage.
The funnel looks like a straight path but in practice people move back and forth between stages; it is a simplifying model, not a fixed rule.
Why it matters
Without seeing where the drop-off happens in the funnel, it is unclear where investment should go. It is the basic framework for deciding whether budget belongs at the awareness stage or the conversion stage. Without it, more budget can end up on a stage that already performs well while the real bottleneck goes unnoticed.
