B equals M times A times P. Motivation, Ability, Prompt. Marketing teams that miss any of the three are running campaigns that do not produce the action they were built for.
The numbers underneath
Section 01 · Quick definition
In one pass
Fogg Behavior Model frames behavior as the product of three elements that must converge at a single moment. Motivation is the buyer's desire to act (hope, fear, social acceptance). Ability is the easiness of the action (steps, time, cost, prior knowledge required). Prompt is the trigger that says "do it now" (a notification, a CTA button, a deadline, a recommendation).
The structural assessment
For a behavior to occur, all three must be present and above their respective thresholds at the same moment. Buyer not clicking the CTA. Buyer not buying. Buyer scrolling past. Each is one of the three elements failing.
Section 02 · Why it matters
Origin.
Most campaigns optimize for one of the three elements and ignore the other two. Performance teams optimize the Prompt (the ad creative, the CTA copy, the email subject). Pricing teams optimize Motivation (discounts, urgency, scarcity framing). UX teams optimize Ability (fewer form fields, faster checkout). The team that optimizes only one element runs into the ceiling the other two impose.
Mechanic.
When a campaign converts poorly the marketing review is almost always one of the three elements. The buyer wanted it but the form was too long (Ability). The buyer could buy it but did not really want it (Motivation). The buyer wanted it and could buy it but never saw the CTA (Prompt). Without checking all three, the team optimizes the wrong lever for months.
Ability is the lever most marketing teams underuse. Reducing the number of form fields. Pre-filling known data. Shortening the checkout flow. Removing the account-creation step. Each Ability gain raises conversion across every buyer segment without changing Motivation or Prompt. Most marketing teams are out of Motivation ideas and stuck on Prompt ideas; Ability is the quiet lever still on the floor.
Section 03 · How it runs
Five operating checks that surface which of the three Fogg elements is the actual leak.
Does the ICP buyer actually want what the offer delivers, in the moment the campaign hits them. Rate 1-5. If the score is below 3 the campaign is targeting wrong, not converting wrong.
How many seconds, clicks, decisions does the action take. Rate 1-5 inversely (5 = very easy). If the score is below 3 the action is too hard. Each friction point can reduce completion; measure the effect instead of assigning a universal percentage.
Is the action prompt visible, urgent, and decision-ready in the moment. Rate 1-5. If the score is below 3 buyers want to act but cannot find the path.
The lowest score is the leak. Fix the leak before optimizing anything else. Optimizing Prompt when Ability is the leak burns budget.
Re-run the Fogg audit after the build ships. The leak moves: fixing Ability often surfaces a Motivation gap that was masked. Iteration is per element, not global.

Section 04 · Common misunderstandings
The Fogg model gets misread by marketing teams in three predictable ways.
Misunderstanding 01
Fogg is a UX framework, not a marketing framework.
Marketing produces behavior; Fogg names what behavior requires. The model is load-bearing for any marketing campaign asking the buyer to act. UX teams use it because UX teams ask for behavior; marketing teams ask for behavior too.
Misunderstanding 02
If the campaign converts, all three elements are working.
Conversion measures only the buyers who completed the action. The Fogg audit measures the buyers who almost completed the action and gave up because one element was missing. The conversion rate hides the failure mode; the Fogg audit surfaces it.
Misunderstanding 03
Motivation is the lever; raise the urgency and conversion follows.
Urgency raises Motivation only if Ability and Prompt are working. A high-urgency campaign hitting a buyer who cannot complete the action in under 2 minutes produces frustrated buyers, not buyers. Ability has to be raised first or in parallel.
Section 05 · Questions to ask
Five questions to surface which Fogg element is the leak on a working campaign.
Can the team rate Motivation, Ability, and Prompt separately on the campaign's ICP?
Is the lowest-scoring element the focus of the current optimization sprint?
Has the action's Ability score (time, clicks, decisions required) been measured in seconds?
Is the Prompt visible inside the buyer's scan zone on the page or in the inbox?
When the campaign underperforms, does the team look at which element failed or does it relaunch with different copy?
Stan's take · four points
Fogg taught the behavior-design class at Stanford. The students who took the class founded Instagram, Google Mail's growth team, and several consumer-fintech companies. The model is used quietly across the products everyone touches daily.
Marketing teams I audit usually have a Motivation campaign running and a Prompt optimization sprint going. They almost never have an Ability sprint. The form has 11 fields when it could have 3. The checkout has 5 steps when it could have 2. The login requires a password when SSO would close the loop in one tap.
Run the Fogg review, rate each element, and test the lowest-scoring constraint. Record engineering cost and conversion evidence on a pre-defined window.
When Ability appears constrained, test a simpler path while holding Motivation and Prompt as stable as practical. Easier does not guarantee a conversion lift.
