Top of Funnel (TOFU)
The awareness stage, where a prospect becomes aware of a problem or a category rather than a product.
What belongs here
Material addressing the problem, not the product. A prospect at this stage is not comparing vendors; they are working out whether the thing they are experiencing has a name and whether anyone has solved it.
The commonest mistake
How to measure it without last-touch thinking
Measure volume, quality and cost separately. TOFU optimised on volume alone reliably produces worse pipeline at a better cost per lead.
Track TOFU cohorts forward to revenue rather than to the next stage. The stages in between hide the effect you actually care about.
Compare downstream conversion by source. Two channels with identical cost per lead frequently differ by multiples in what they eventually close.
Accept a lag matched to your sales cycle. Judging TOFU on in-quarter pipeline in a long-cycle business measures the wrong quarter.
Hold one channel constant when testing another, or attribution noise will swamp the result.
Where it misleads
TOFU is the hardest stage to attribute, so the channels that are easiest to measure receive credit disproportionate to their contribution.
Cost per lead is the most gameable metric in the funnel, and the cheapest leads are frequently the least likely to buy.
Brand and community effects operate at the top of the funnel and are largely invisible to any attribution model.
Judging TOFU on short-run pipeline creates pressure towards bottom-funnel tactics that harvest existing demand rather than create it.

Attracting prospects by publishing material they seek out, rather than by interrupting them.
Bottom of Funnel (BOFU)
The decision stage, where a prospect is comparing specific options and evaluating fit, price and risk.

Publishing material that attracts and informs a defined audience, building durable demand rather than renting attention.
Attribution Model
The specific rule assigning credit for a conversion across the touchpoints that preceded it.
Demand Generation
The discipline of creating awareness and interest in a category and a product, as distinct from capturing demand that already exists.
COMMON QUESTIONS
- What is top of funnel?
- The awareness stage, where a prospect becomes aware of a problem or a category rather than of a specific product. The buyer's question is 'what is this and does it matter to me', which is why product-led content performs poorly here.
- How do you measure top of funnel?
- By tracking cohorts forward to revenue rather than to the next stage, and by comparing downstream conversion across sources rather than cost per lead. Two channels with the same cost per lead frequently differ by multiples in what they eventually close, and only the forward view shows it.
- Why does top of funnel look inefficient?
- Because it is the hardest stage to attribute and the furthest from revenue. Channels that are easy to measure get credit that belongs partly to channels that are not, and brand and community effects are largely invisible to any attribution model — so TOFU is systematically under-credited.
- Should you invest in TOFU or BOFU?
- Diagnose first. If bottom-funnel conversion is strong but volume is thin, the constraint is upstream and more BOFU work polishes a small number. If volume is fine and conversion is poor, more awareness simply delivers more prospects to a stage that is failing them.
