AIDA has been doing the rounds since the 1890s. PAS arrived later, leaner and considerably less polite. Both are still taught, both still sell books, and both can flatten a decent piece of copy when used in the wrong place. The question is not which formula is better. It is which one your reader needs at the moment they meet your words.

What AIDA actually asks you to do

Attention, Interest, Desire, Action. Four moves, in order. You stop the scroll, you make the reader curious, you turn curiosity into wanting, then you ask for something specific.

It suits copy where the reader does not yet know they have a problem, or knows they have one but has never connected it to a solution like yours. Long sales pages, launch emails, a landing page for a debut novel. Anything unfamiliar needs orienting before it can be wanted.

A book landing page built on AIDA might run like this:

• Attention: “Most family historians give up in month three.”
• Interest: two lines on why that happens and what changes for the reader.
• Desire: what is inside the book, a sample chapter, a few specific reader comments.
• Action: “Read the first chapter free.”

The weakness sits in the middle. Interest and Desire are the hardest two sections to write and the easiest to fake. Copy that is pleasant but never builds wanting stalls exactly where AIDA should be doing its heaviest lifting. If your Desire section is really just a feature list, it is not desire. It is a catalogue.

What PAS does instead

Problem, Agitate, Solution. Three moves. Name the problem in the reader’s own words, show what it costs them, then offer the fix.

PAS earns its keep when the problem is already felt. Someone typing “how do I stop rewriting my first chapter” does not need persuading that a problem exists. They need recognition, then relief.

Your manuscript has been nearly finished for eight months. Every read-through turns into another rewrite, and the draft drifts further from done. Self-Editing Your Novel gives you a chapter-by-chapter pass you can complete in a fortnight.

Notice how much of that is agitation. That is normal — the agitation is the work.

The place people overreach is the middle word. Guilt, fake scarcity and manufactured fear read as manipulation, and readers spot them quickly. Agitate honestly: describe the cost precisely instead of inflating it. “Eight months” is stronger than “years of misery” because it is specific and checkable.

The real difference between them

AIDA builds a case. PAS presses a bruise.

AIDA assumes a stranger. PAS assumes someone already looking. AIDA is a structure you fill; PAS is a lever you pull. That is why PAS survives being cut down to a subject line or a single paragraph, while AIDA needs room to breathe.

Choosing between them

Use these questions as a filter before you start writing.

• Does your reader already know they have the problem? Yes — use PAS. No — use AIDA.
• How familiar is the offer? A well-known category needs less explaining, so PAS usually fits. Something unusual needs AIDA.
• How much space do you have? Subject lines, ads and social posts lean PAS. Landing pages and sales emails lean AIDA.
• How sensitive is the subject? For grief, health, debt or anything where the reader may already feel blamed, agitation can land badly. AIDA is often the kinder route.
• Are you selling a feeling or a fix? Emotional payoffs suit PAS. Practical, considered purchases often do better with AIDA.

If you are unsure, write the PAS version first. It takes ten minutes, and it will tell you whether the problem is sharp enough to carry a longer piece.

Adapting both for book marketing

Blurbs

Genre fiction and problem-solving non-fiction usually want PAS: state the situation, tighten the screw, promise the resolution. Memoir and literary fiction often want AIDA, because the reader has no problem to solve — the pull is voice, curiosity and the promise of an experience.

Ads and social posts

Short formats favour PAS. Save AIDA for when you genuinely have to explain what the thing is: a serialised novel, a crowdfunded art book, an audio-first title. AIDA’s Interest section exists precisely to do that explaining.

Email sequences

Mix them across a sequence rather than inside one email. Open with a PAS subject line and first paragraph, then build desire across two or three AIDA-shaped emails, each ending with one clear action. Keep the tone consistent; a chatty agitate followed by corporate desire reads like two different authors wrote it.

Blending without making a mess

AIDA with a PAS opening is one of the most reliable structures in commercial copy: agitate to earn attention, then build interest and desire. Two rules keep it clean. Match the size of your solution to the size of the problem — a long, heavy agitation followed by a thin offer feels dishonest. And pick one voice. Switching registers mid-page breaks the spell faster than a weak headline.

A thirty-second check before you publish

1. Could a stranger say what this is selling after one read?
2. Does every line earn the next one, or is some of it just filling space?
3. Does the final call to action name one specific thing — “read the first chapter”, not “find out more”?
4. Would any sentence work just as well in a competitor’s copy? If so, cut it or sharpen it.

Start with the reader, not the formula

Formulas are scaffolding, not substance. Ask what your reader already believes, feels and worries about, then choose the structure that meets them there. If they arrive knowing the problem, agitate and solve. If they arrive cold, earn their attention first and build from there. Write the version that fits, then read it aloud. The one that sounds like a person talking to a person is the one to keep.
