Marketing Funnel is a framework for understanding how people move from awareness to consideration, conversion, and loyalty.
It matters because strategy keeps channels from competing with each other. When this concept is clearly defined, the team can connect budget, audience, creative, offer, tracking, and reporting to revenue instead of chasing disconnected metrics.
Example
A team groups activity into discovery, evaluation and inquiry stages to organize reporting. The funnel is a planning model: an individual buyer may revisit earlier questions or skip steps rather than move through it in a straight line.
