Marketing Funnels
Date: 2026-09-27
A planning model that sorts marketing by how close the audience is to buying — top, middle, bottom. Useful for budgeting and for matching message to readiness; wrong as a description of how any individual actually buys, and wrong in a way that attribution then makes worse.
A marketing funnel is a model that divides a market into stages of purchase readiness and assigns each stage its own channels, messages and metrics.
The shape
STAGE WHO'S THERE JOB OF THE MARKETING TYPICAL METRIC
─────────────────────────────────────────────────────────────────────────────────────────────
TOP (awareness) don't know you, may not make the category and reach, video views,
TOFU know they have the problem the brand familiar branded search lift
MIDDLE (consideration) know the problem, comparing give reasons to shortlist engaged visits, email
MOFU options you signups, return visits
BOTTOM (conversion) ready to buy, choosing remove the last objection, conversion rate,
BOFU where be findable cost per acquisition
TOFU, MOFU, BOFU — top, middle and bottom of funnel. Shorthand in every agency deck.
Older names for the same thing: AIDA (attention, interest, desire, action), usually attributed to the advertiser E. St. Elmo Lewis around the turn of the twentieth century. See-Think-Do-Care, Avinash Kaushik’s variant, adds the post-purchase stage most funnels leave out.
What it’s good for
- Budget allocation by stage. Forces the question “what are we doing for people who aren’t ready yet?” — which a business run on last-click reporting stops asking
- Matching message to readiness. A retargeting ad and a prospecting ad are different products; one needs a reason to act now, the other a reason to care at all — Paid Social
- Picking the right metric per stage. Judging awareness spend on cost per acquisition is the most common mistake the funnel prevents
Where it misdescribes buying
People don’t move through it in order. They loop, skip and stall. Someone sees a friend’s purchase and buys the same day — top to bottom in one step. Someone else spends six months in the middle.
It implies a pipe, which implies you can push volume in at the top. Most people at the top of a funnel will never be in-market, whatever you spend. Only a small share of a category is buying at any moment; the rest is being made familiar for later — Demand Creation vs Demand Capture.
It has no exit into the next customer. The funnel ends at purchase. Businesses that grow through referral, content or network effects are better drawn as loops — Growth Loops.
How attribution turns the model against itself
THE PATH WHAT LAST-CLICK CREDITS
─────────────────────────────────────────────────────────────────────────
week 1 sees a video ad (top) –
week 3 reads a comparison article (middle) –
week 6 searches the brand name, clicks ad 100% ← bottom
Every bottom-of-funnel channel sits closest to the sale, so click-based models reward it. Budget drifts downward, the top starves, and months later the bottom has less to harvest — the decline looks like a search problem when it’s an awareness problem — Attribution Models, Incrementality Testing.
Using it without being misled
- Treat it as a portfolio split, not a sequence. “What share of spend reaches people who aren’t in-market?” is the useful question — Channel Mix
- Measure the top with its own evidence. Branded search volume, direct traffic, Self-Reported Attribution, geo tests — not click conversions
- Don’t confuse it with a funnel report. An analytics funnel is a measured sequence of steps on your own site; a marketing funnel is a planning abstraction across channels you mostly can’t observe — Funnel Analysis
- Leads are a separate funnel. Where the conversion is a form fill, the bottom of this funnel is the top of a sales one — Lead Funnel Stages
