What is a marketing funnel?
What are the stages of a funnel?
Most versions use three.
- Awareness. The person learns that you exist.
- Consideration. They compare you with other options.
- Purchase. They buy, or they do not.
You will also see the labels TOFU, MOFU and BOFU. They mean top, middle and bottom of the funnel. Same three stages, shorter words.
The shape is a funnel because, in theory, fewer people make it through each stage than entered it. Some versions add stages after purchase, such as repeat orders. The idea stays the same.
Why do brands use it?
A funnel gives a team a shared vocabulary. It helps answer a plain question: where are we losing people? If a lot of visitors arrive and few buy, the problem sits in a different place than if few visitors arrive at all.
That only works if each stage has a number attached. "Awareness is low" is an opinion. "Few people reach a product page" is something you can check.
Where does the model mislead?
A funnel suggests a straight line. Real buying is not one. Someone sees an ad, forgets you, searches your name weeks later, reads a review and leaves. Then they come back through an email. Which stage was that?
The model also makes it easy to credit the last step. The final click gets the sale. The earlier steps look like cost. That is an attribution problem, and a funnel diagram does not solve it.
Our view: Use the funnel to ask where the plan leaks. Do not use it as proof that every stage needs budget.
Easily confused with
Funnel vs Full-funnel
The funnel is the model. Full-funnel is a plan to spend across all of it. Different thing, different risk.
Funnel vs Always-on
A way of scheduling ads (continuously), not a stage of the customer path.
Funnel vs Attribution
The method of crediting a sale to touchpoints. The funnel only describes stages.
Buzzword alert
"We will fill the top of the funnel"
Usually means: more spend on reach, with success measured by reach.
Ask: which number at the next stage should move because of it?
FAQ

Is the marketing funnel the same as the sales funnel?
Mostly yes. People use both names for the same staged model. Some use "sales funnel" for the later stages, nearer the purchase.
Do customers really move through a funnel in order?
Not reliably. People skip stages, repeat them and go back. The funnel is a planning tool, not a description of one person's path.
Can a small brand use a funnel?
Yes, and it is simpler than it sounds. Write down the stages, pick one number per stage and look at where it drops.
