FAB — Classic

Features · Advantages · Benefits

The antidote to feature-heavy copy. Forces every product claim to answer the reader's silent question: "So what?"

What is the FAB formula?

FAB — Features, Advantages, Benefits — is the simplest framework for writing benefit-first product copy. Its core insight is that customers don't buy features; they buy what those features do for them. FAB forces you to take every product claim through three layers: what it is, what it does, and — most importantly — why the reader should care. Apply it to any product bullet point, and watch generic specs become emotionally resonant selling points.

The 3 stages of FAB

F
Stage 1
Feature
What it is or has. "256GB storage."

The Feature is the objective, factual attribute of the product — the spec sheet entry. '256GB storage.' 'AI-powered grammar checker.' Features are necessary but insufficient — they inform, they don't persuade. State them precisely, then push through to Advantage and Benefit.

Do
  • State it factually and precisely
  • Use it as the starting point, not the selling point
Don't
  • Lead with features in your headline or hero copy
  • Assume readers understand why a feature matters
A
Stage 2
Advantage
What it does. "Holds 100,000 photos."
B
Stage 3
Benefit
Why it matters. "You'll never delete a memory to free up space again."

Why it works

  • Forces benefit-first thinking on every claim
  • Easy framework to apply to any product feature
  • Makes technical specs feel human and relevant
  • Great for training non-copywriters to write better

Common mistake

Stopping at the Advantage and calling it a Benefit. "Holds 100,000 photos" is an advantage. "Never lose a memory" is the benefit. Keep asking "so what?" until you hit emotion.

If your bullet starts with "It has…" or "Includes…" you're writing features. Rewrite it to start with "You get…" or "So you can…" to reach the benefit.

Common mistakes

Stopping at the Advantage
Fix'Holds 100,000 photos' is an Advantage. 'You'll never delete a memory again' is the Benefit. Keep asking 'so what?' until you reach emotion.
Generic benefits
FixBenefits that could apply to any product are filler. 'Saves you time' is not a benefit. 'Gets 3 hours of Monday back' is.
Feature-first headlines
FixHeadlines should lead with the Benefit. Readers scan for what's in it for them, not for specs.
