Copywriting formulas aren't templates you fill in. They're scaffolds that organize persuasion into a sequence the reader can follow. The three most useful. AIDA, PAS, and PASTOR, cover 95% of direct response situations. Learn all three; use each where it fits.
The oldest copywriting formula, usually credited to Elias St. Elmo Lewis (1898). A classic for a reason.
A. Attention: "The #1 reason your reps miss quota isn't what you think."
I. Interest: "It's not leads. It's not tools. It's not motivation. It's the 14 minutes per day they spend on CRM hygiene. 67 hours a year, gone."
D. Desire: "Our customers eliminated that time using a single automation. Their reps closed 31% more in Q3 than Q2, same pipeline, same quota, 67 more hours of actual selling."
A. Action: "Book a 15-minute demo. Walk through the automation. See if it fits your stack."
PAS is a favorite of mine. It goes deep on the problem before presenting the solution. The agitation creates the tension that the solution then releases.
P: "Your CAC went up 28% this year. You already know this. What you might not know, your top 3 SKUs now take 4 sessions to convert, not 2."
A: "Each of those added sessions costs you another $0.82 in paid traffic, another hit to creative fatigue, another risk of the buyer discovering a cheaper competitor mid-consideration. Over the next 12 months, that compounds to six figures in lost margin, and your Q4 plan doesn't account for it."
S: "The fix is a specific retention email sequence that caught 41% of those wandering buyers for our last 3 clients. We send it to you for free, no call required. Reply 'send' and it's in your inbox in 10 minutes."
Don't just restate the problem louder. Agitation is about consequences. What happens if they don't fix it? What does Monday morning look like in 12 months? What do they feel at 11pm when the dashboard tells them the truth? Specificity in agitation is what separates PAS from whining.
An expansion of PAS, designed for longer-form direct response, sales letters, VSLs, long emails.
The "S" in PASTOR is the difference between a mediocre long-form piece and a great one. Readers believe stories more than they believe claims. A specific founder's journey. "I was in your situation two years ago, here's what happened", builds identification in a way proof alone can't.
| Context | Best formula |
|---|---|
| Short ad, impulse purchase | AIDA |
| Cold outreach email | PAS |
| Social ad โ landing page | AIDA |
| B2B problem-aware email | PAS |
| Long-form sales letter (3000+ words) | PASTOR |
| VSL (20+ minutes) | PASTOR |
| Course / coaching launch sequence | PASTOR |
| Retargeting ad to warm audience | AIDA (shortened) |
Formulas are training wheels. Eventually you internalize the underlying structure, attention โ interest โ belief โ action, and compose in whatever order fits the specific reader's journey. A/B testing will tell you whether you've earned the right to break the formula; if the numbers don't support it, go back to the scaffold.
A formula-filled piece of copy with a weak offer or a wrong market still fails. The formula organizes persuasion; it doesn't create persuasion out of nothing. If you're hitting a wall on the copy, the problem is usually upstream, offer, market, or dream customer, not the formula.
