TOFU, MOFU and BOFU (top, middle and bottom of funnel)
Also known as: top of funnel, middle of funnel, bottom of funnel, funnel stages
TOFU, MOFU and BOFU stand for top, middle and bottom of the funnel, the three stages the buying journey is usually divided into. At the top, people notice a problem and try to understand it; in the middle, they consider solutions and compare; at the bottom, they choose a provider and buy. Each stage calls for its own kind of content, offer and metric.
A language school organizes its content by the three stages. At the top, an article on how long it takes to become fluent. In the middle, a comparison of online and in person classes, with what changes in price and results.
At the bottom, the free trial class page, with plan prices, testimonials and schedules. People reading the top article rarely buy on the spot, but that article is what brings them to the comparison and, weeks later, to the trial class.
What customers need at each stage
| The customer wants | Typical content | Main metric | |
|---|---|---|---|
| Top (TOFU) | To understand the problem | Articles, short videos, posts | Reach, traffic, new contacts |
| Middle (MOFU) | To compare options | Guides, comparisons, webinars, cases | Leads, engagement, qualified leads |
| Bottom (BOFU) | To decide and buy | Demos, quotes, free trials, pricing | Opportunities, sales, cost per customer |
Keywords by stage
Bottom of funnel searches have less volume and much more buying intent. That is why search ads usually start with them, while organic content works all three stages.
- Top: searches like what is, how to, why does.
- Middle: best, comparison, is it worth it, alternative to.
- Bottom: price, quote, hire, near me, the brand name.
Two opposite mistakes
The first is staying at the top: lots of traffic, lots of followers, few sales, because nothing leads people to a decision. The second is staying at the bottom: expensive ads fighting over the same few buying searches, without building the demand that becomes tomorrow's buying search.
A balanced plan connects the stages: each top piece points to a middle one, and each middle piece points to a bottom offer.
The model's limits
The funnel is a useful simplification, not an accurate portrait. Google's research on the messy middle showed that, between trigger and purchase, people switch between exploration and evaluation many times instead of moving down the stages in order.
In practice, the same person may read a top of funnel piece after already requesting a quote. That is why each stage's content needs to be available all the time, not only in a fixed sequence.
