Landing page copywriting frameworks: PAS, AIDA, BAB and when they fail

Copywriting frameworks are templates for the order of an argument. They're useful when you're staring at a blank page, and they're behind a lot of landing pages that work. They're also behind a lot of copy that sounds like every other page, because the framework was followed and the thinking was skipped.

This guide covers four common frameworks, how each maps to a landing page, and when they fail.

PAS: Problem, Agitate, Solution

The structure: name the problem, make the reader feel its cost, then present the solution.

On a landing page: the hero names the problem, the next section shows what it costs (time, money, risk), and the rest presents the product as the way out.

Example (a made-up invoicing tool):

Problem: Late payments are eating your cash flow. Agitate: Every week you spend an afternoon sending reminders, and still wait 60 days to get paid. Solution: Acme sends invoices and follow-ups for you, so clients pay on time.

Works best for: visitors who know the problem but not your solution. Fails when: the agitation is exaggerated or invented. Readers notice, and it reads as manipulative.

AIDA: Attention, Interest, Desire, Action

The structure: get attention, build interest with relevant information, create desire by showing the benefit, then ask for the action.

On a landing page: a headline that stops the scroll, a section that explains what it does, a section of outcomes and proof, then the call to action.

Works best for: a general page structure, especially for longer pages. Fails when: "attention" turns into a clever headline that doesn't say what you sell. Attention is worthless if the visitor doesn't understand what they're looking at.

BAB: Before, After, Bridge

The structure: describe the reader's world now, describe it after the problem is solved, then show the product as the bridge.

On a landing page:

Before: Invoices in a spreadsheet, reminders sent by hand. After: Clients pay on time without you chasing them. Bridge: Acme sends the invoice and the follow-ups automatically.

Works best for: products whose value is easy to picture as a change in someone's day. Fails when: the "after" is vague ("transform your workflow") instead of something the reader can picture.

The 4 Ps: Picture, Promise, Prove, Push

The structure: paint a picture of the outcome, make a specific promise, prove it, then push for the action.

On a landing page: an outcome-focused hero, a clear promise in the subline, a block of proof, and a call to action with a reason to act now.

Works best for: pages where proof is strong. Fails when: the "prove" step is missing or vague, which leaves a big promise standing on nothing. See social proof that persuades skeptics.

What all good frameworks have in common

Under the different names, each framework does the same few things:

1. Start where the reader is: their problem or situation, not your product.
2. Show the change: what's different after.
3. Make it believable: specifics and proof.
4. Ask for one clear action.

If your page does those four things in a sensible order, it doesn't matter which framework you used, or whether you used one at all.

When frameworks fail

Generic inputs give generic copy. A framework structures your argument; it can't supply it. If you don't know the reader's real problem, the alternative they use today, and why you're better, any framework will produce filler. Start with your value proposition.

The wrong framework for the reader's awareness. PAS spends its opening on the problem. That's right for visitors who've just realised they have it, and wasted on visitors who are comparing vendors. See customer awareness stages.

Following the steps too literally. Real pages mix structures: a clear description in the hero (so visitors know what this is), a PAS section for the problem, proof throughout, a BAB-style section for the outcome. The framework is a guide, not a form to fill in.

Exaggeration. Agitation and desire are where copy turns into hype. Overstated pain or promises make skeptical readers trust the whole page less.

How to check your copy

Read the page as your most skeptical buyer would and ask, section by section: Do I know what this is? Is it for me? Why should I believe it? What do I do next?

You can also hand that job to a simulated panel. Klar has five buyer personas, including a skeptic and a busy professional who gives the page a few seconds, read your page and say where they lost interest or stopped believing. The positioning check shows whether your copy answers what it is, who it's for, what it replaces and why it's better. And Copy Lab tests different hero versions, for example a PAS opening against a plain description, against the same panel. The personas are simulated, so use them to choose what to test with real buyers.
