Ad copy frameworks that actually work

Three battle-tested formulas — AIDA, PAS, BAB — and the specific phrases that lift CTR by 30-100% on real accounts.

Most ad copy is bad because the writer started with "what should I say about my product?" The good frameworks start with "what is my customer thinking, and how do I match them?"

1. AIDA — Attention, Interest, Desire, Action

The classic. Best for cold audiences who don't know you yet.

  • Attention: a hook that stops the scroll.
  • Interest: a benefit they care about.
  • Desire: proof or specificity that makes them want it.
  • Action: tell them exactly what to do.

"Your Google Ads bill is 30% bigger than it should be." (attention)
You're paying for searches that never convert. (interest)

2. PAS — Problem, Agitate, Solve

Best when the customer already feels the pain. Common in B2B and high-consideration purchases.

  • Problem: name the thing they hate.
  • Agitate: remind them why it sucks.
  • Solve: here's the fix.
PAS for a project management tool
Problem: "Slack threads, email chains, and three different docs for one project."
Agitate: "Half your team's day is spent searching for the latest version."
Solve: "One source of truth. Free for 14 days."

3. BAB — Before, After, Bridge

Best when transformation is the value prop. Fitness, productivity, finance, education.

  • Before: their current state.
  • After: the desired state.
  • Bridge: your product is the way to get there.

Headline formulas that almost always work

  • Number + benefit + timeframe. "Get 50 leads in 30 days."
  • Question they're already asking. "Why are your ad costs up 40% this year?"
  • "Even if [common objection]" framing. "Run cross-platform ads — even if you've never used Google Ads."
  • Social proof + outcome. "200+ agencies use SEM to cut reporting time by 80%."
  • Risk reversal. "Try free for 14 days. No card required."

The phrases that consistently lift CTR

  • "For [specific audience]" — "For agencies with 10+ clients."
  • "Without [common drawback]" — "Without the spreadsheets."
  • "In [specific timeframe]" — "In 5 minutes a week."
  • "Trusted by [specific number/customer]" — "Trusted by 200+ marketing teams."
  • "Stop [hated thing]" — "Stop reconciling reports at midnight."

The 5 things to never put in ad copy

  • Your tagline. "Innovation, redefined." Means nothing. Cut it.
  • "Welcome to [Company]." They don't know you yet, they don't care.
  • Generic adjectives. "Best," "leading," "top-rated" without proof. Specifics convert; superlatives don't.
  • The word "solution." Almost always lazy writing. Be specific about what you do.
  • Three CTAs. One CTA per ad. The user is already overwhelmed.

How to know your copy is good

Show your ad to a friend in a different industry for 5 seconds. Cover the logo. Ask:

  • What does this company do?
  • Who is it for?
  • What should you do next?

If they can answer all three in 5 seconds, the copy is working.

Don't write one ad — write five
Modern ad platforms test combinations of headlines and descriptions automatically. Give them 5 headlines + 4 descriptions and let the algorithm find what wins. Writing one "perfect" ad means leaving 30-50% of CTR on the table.
