No matter what kind of purchase we’re making or how much we intend to spend, all of us follow a relatively similar path when it comes to deciding what to buy. This buying process, or stages, was first introduced by John Dewey in 1910, but even now — more than 100 years later — it’s still the foundation of understanding buyer behavior and marketing funnel creation.
If you're wondering what a sales funnel is, simply imagine a real-world funnel. At the top of that funnel, some substance is poured in, which filters down towards one finite destination. In sales, something similar occurs. At the top, lots of visitors arrive who may enter your funnel. However, unlike the real-world funnel, not all who enter the sales funnel will reemerge out from the other end.
