Copywriting formulas: AIDA, PAS and how to use them

Copywriting formulas are reusable structures for persuasion — tested patterns that carry a reader from attention to action. They are not magic words. They are a running order, so you write in the sequence a reader actually makes a decision, instead of guessing what comes next.

Used well, a formula stops you leaving out something the reader needed. Used badly, it becomes a template you fill in without thinking. This guide covers the two formulas worth knowing first — AIDA and PAS — with the same fictional product written both ways, then a handful of others and, most importantly, how to choose.

Why formulas exist

People buy in a rough order. First they have to notice. Then they have to care. Then they have to believe. Then they have to act. Formulas are just named versions of that order, written down by people who sold things and noticed what worked. They exist so you do not have to rediscover the sequence every time you face a blank page. A blank page is where most copy dies; a formula gives you a first move, and a first move is usually all you need to get going.

Our worked example throughout: a fictional product called DeskReset, a small standing-desk converter for people who work from home and ache by mid-afternoon.

AIDA: attention, interest, desire, action

AIDA is the oldest and most general structure. Attention: stop the reader with something that matters to them. Interest: hold it with detail they care about. Desire: turn interest into wanting, usually by making the outcome vivid and believable. Action: ask clearly for the next step.

DeskReset in AIDA: “By 3pm, your back has had enough (attention). DeskReset lifts your existing desk from sitting to standing in two seconds, no tools, no new furniture (interest). Stand for an hour, sit for an hour, and finish the day without the ache that used to follow you to dinner (desire). Try it for 30 days — if your afternoons are not better, send it back (action).”

PAS: problem, agitate, solution

PAS is tighter and often stronger when the reader already feels a pain. Problem: name it plainly. Agitate: show what it costs if nothing changes — honestly, not cruelly. Solution: present your offer as the relief.

DeskReset in PAS: “Your back hurts by mid-afternoon (problem). It is not just today — another year hunched over the same desk and the ache becomes the reason you stop working early, skip the evening walk, and sleep worse (agitate). DeskReset turns your current desk into a standing desk in two seconds, so you can change posture through the day without buying new furniture (solution).”

Same product, same facts, two different running orders. AIDA opens with a hook and builds want; PAS opens with the pain and offers escape. Neither is better in the abstract. Which one wins depends on the reader.

Three more, briefly

• 4Ps — promise, picture, proof, push. Make a promise, paint the picture of life with it, prove it with evidence, then push for the action. Good when you have strong proof to show.
• BAB — before, after, bridge. Describe life before, life after, and the bridge that gets the reader across. Quick and clean for ads and short emails.
• Star, story, solution. Introduce a relatable character, tell a short story of their struggle, then reveal the solution. Strong when trust and emotion matter more than speed.

You do not need all of them. Learn AIDA and PAS well, keep the other three in your back pocket, and you can structure almost any piece of direct response.

How to choose a formula by awareness level

The best predictor of which formula to use is how aware your reader already is of their problem and your solution. A reader who does not yet feel the problem needs to be led into it — AIDA, or star-story-solution, which take time to build. A reader who feels the pain sharply does not need convincing that it hurts; they need relief fast — PAS, or BAB. A reader who already knows your product and just needs a reason to act today needs almost no build at all — lead with the offer and the deadline.

Match the structure to the reader’s starting point, not to your favourite formula. This is the single judgement that separates writers who use formulas well from those who force every product through the same one.

The mistake: filling in a formula without research

A formula tells you the order. It cannot tell you what to say. The words that fill each step — the exact problem, the words the reader uses for it, the proof they will believe, the outcome they actually want — come from research, not the template. Skip the research and you get copy that is perfectly structured and completely generic: “Struggling with X? Agitate agitate. Introducing our solution!” It follows PAS to the letter and persuades no one, because nothing in it sounds like the reader’s real life.

Think of the formula as the skeleton and your research as the muscle. A skeleton with no muscle cannot move. This is also how a formula improves a full sales page: it orders the sections, but the research is what makes each section land.

When to break the formula

Formulas are scaffolding, and scaffolding comes down once the building stands. As you get more fluent you will feel when a step is unnecessary — a reader who already trusts you rarely needs a long agitation — or when two steps should merge into one sharp line. Breaking a formula on purpose, because you understand what each step was doing, is a sign of skill. Ignoring the structure because you never learned it is not. Learn the order first; earn the right to bend it second.

For students and educators

Here is the exercise that teaches this fastest. Take one product — real or invented — and write it twice, once in AIDA and once in PAS, no more than 120 words each. Then read both aloud and ask which one you would answer, and why. Students learn more from writing the same product two ways than from any amount of theory, because the difference is suddenly in their own hands. Pair this with the guide to direct response copywriting and the five sales obstacles, and find more classroom material in the free resources library.

Frequently asked questions

What is the most effective copywriting formula?

There is no single best one. AIDA suits readers you must warm up; PAS suits readers already in pain. The most effective formula is the one that matches your reader’s awareness.

What is AIDA?

Attention, interest, desire, action — a four-step structure that carries a reader from first noticing to taking the next step. It is the most general copywriting formula.

What is PAS?

Problem, agitate, solution — name the reader’s problem, show what it costs to ignore, then present your offer as the relief. It is tight and effective when the reader already feels the pain.

Do professional copywriters actually use formulas?

Yes, though often without naming them. Experienced writers internalise the patterns and reach for them by instinct, then break them deliberately when the reader calls for it.
