A funnel is a path, not a page
Picture a real funnel: wide at the top, narrow at the bottom. A sales funnel works the same way. A large group of strangers enters at the top — people who just discovered you exist — and a smaller, more committed group emerges at the bottom as customers. The funnel is the deliberate path that carries them from one end to the other.
The stages have names, but the idea is simple. Awareness: someone learns you exist. Interest: they start paying attention. Decision: they weigh whether you're right for them. Action: they call, book, or buy. Each stage asks a different question and needs a different answer, and a good funnel gives the right answer at the right moment.
The reason this matters is that people almost never go from "never heard of you" to "take my money" in a single leap. They move in steps. A funnel respects those steps instead of demanding the whole commitment up front.
