Copywriting Frameworks: AIDA, PAS and BAB Explained with Examples
7 min read · AstraLoop Studio
The blank page is where most copy dies. Not because you're short on product information, but because you don't know what order to say it in. That's exactly what copywriting frameworks are for: scaffolding that tells you what to write and in what sequence, taking you from "I don't know where to start" to a first draft in ten minutes.
They're not magic formulas and they don't replace a clear offer or knowing your customer: they're accelerators built on top of deeper persuasive copywriting techniques. In this guide we'll look at the three most useful ones for B2B customer acquisition (AIDA, PAS and BAB), each with its own logic, a concrete case, a ready-to-use template for emails and ads, and the prompt to have an AI write it.
AIDA: Attention, Interest, Desire, Action
AIDA is the oldest framework and the classic starting point for cold B2B lead generation, when you're talking to someone who doesn't know you and may not even realize they have a problem yet. It guides you through four steps:
- Attention: stop the scroll with a relevant hook (a stat, a question, a counterintuitive claim).
- Interest: explain why it matters to them, with a specific benefit, not a generic one.
- Desire: make the outcome tangible with proof, numbers, or a concrete scenario.
- Action: ask for one clear step, and only one.
AIDA's limit is that it can feel slow: the four stages pay off when you have room to work with (a text-heavy ad, a landing page, a video), less so in a two-line message. If the audience already knows about the problem, PAS often gets to the point faster.
Example: Meta ad for a custom CRM
Attention: "Still juggling quotes and follow-ups between Excel and WhatsApp?"
Interest: "Every lead you don't call back quickly goes cold. A CRM built around your process lines them up and tells you exactly who to call right now."
Desire: "The business owners we work with stop losing deals to forgetfulness and get hours back every week."
Action: "Book a 20-minute demo: we'll show you the flow using your own case."
A note on the numbers: they're deliberately generic here, but in real copy they need to be replaced with your actual data. A made-up stat the client can disprove is worth less than no stat at all. If you work a lot with ads, you'll find more hooks in our guide to Facebook ad copy that sells.
PAS: Problem, Agitation, Solution
PAS is the most direct framework and often the most effective for direct response. It performs best when the reader is already aware of the problem, or recognizes it in the first line. The structure:
- Problem: name the problem in the customer's own words.
- Agitation: show the consequences of not solving it (lost time, money, risk), sticking to the facts.
- Solution: present your offer as the easiest way out.
The typical mistake is skipping the agitation step for fear of sounding negative. But that's exactly where the reader understands why to act now instead of "someday." Agitating doesn't mean scaring people: it means making vivid a cost the customer is already paying without noticing. In B2B the ethical line is simple: you work with a real, verifiable problem, not a made-up fear. Your reader is a professional, and if they smell manipulation, you've lost the deal before it started.
Example: B2B cold email for a qualified appointment-setting service
Subject line: Does your sales rep spend half the day hunting for contacts?
Problem: "Hi Mark, a good salesperson is expensive. If they're spending their days scrolling LinkedIn and dialing cold numbers, you're paying a closer to do a setter's job."
Agitation: "You already know how it ends: a calendar full of dead-end calls, shaky forecasts, and the whole month riding on the last week."
Solution: "We only put pre-qualified appointments on your calendar, so you talk only to people with budget and interest. Got 15 minutes for a call to see if it makes sense for you?"
The rules for not getting ignored (subject line, length, personalization) are in our guide to B2B cold emails that get a reply.
BAB: Before, After, Bridge
BAB tells a transformation story and is perfect when you're selling a change of state rather than a single feature. It shines in landing pages, nurture emails and case studies. Three moves:
- Before: capture the current, uncomfortable situation.
- After: paint the world after the problem is solved, concrete and desirable.
- Bridge: show how your product bridges the two, and invite action.
It works because it mirrors the story the customer is already telling themselves: where I am now, where I'd like to be. That's why it's the natural structure for case studies, where the "after" isn't something you promise but something a real customer demonstrates.
Example: landing page section for follow-up automation
Before: "Today the quote goes out, then silence sets in. Whoever was supposed to follow up was on vacation, the lead went cold, and that 8,000-euro deal is now forgotten."
After: "Imagine every unclosed quote getting followed up automatically, at the right moment and with the right message, until the customer decides. No deal ever left hanging."
Bridge: "That's what a follow-up flow connected to your CRM does. We set it up around your process in a couple of weeks."
Which framework to use, and when
They're not competing with each other: they're often combined. An AIDA ad leads to a BAB landing page, and whoever doesn't convert enters a PAS email sequence. The choice mostly depends on how aware the reader already is of the problem.
| Framework | Best for | Ideal channel | Awareness level |
|---|---|---|---|
| AIDA | First cold contact | Ads, long landing pages | Unaware / problem-aware |
| PAS | Problem already felt | Cold email, direct-response ads | Problem-aware |
| BAB | Selling a transformation | Landing pages, nurturing, case studies | Solution-aware |
If you're not sure where your reader stands, start from the five levels of customer awareness: it's the variable that decides, more than any other, which structure works.

How to get an AI to write these frameworks
A generic AI produces generic copy. The leap happens when you give it three things together: the framework, the product context and your voice. Here's an adaptable prompt skeleton:
"You are an expert copywriter in [industry]. Write a [cold email / ad] using the PAS framework. Product: [two-line description]. Target customer: [role, company type, main problem]. Concrete benefit: [real number or result]. Tone: [three adjectives describing your brand voice]. Constraints: max [X] words, a single call to action, no superlatives, prices in local currency format. Return 3 variations."
What actually matters: an explicit framework, a specific target instead of "generic SMBs," a single call to action, and asking for multiple variations to test. The factor that truly makes the difference remains brand voice: if you have to describe your tone in every prompt, you waste time and lose consistency, so for ongoing use it pays to train the model on your voice once and be done with it. For building stronger prompts, this collection of ChatGPT copywriting prompts is a good starting point. The principle doesn't change: the AI produces the first draft in minutes, you remain the editor who cuts and verifies.
The real advantage kicks in when you're not generating one piece at a time but an entire, coherent pipeline: the AIDA ad, the BAB landing page it points to, and the three PAS emails for whoever didn't convert. A system set up once produces this sequence for every new offer in minutes, with the same tone across every touchpoint. That's when copywriting stops being a bottleneck.
Mistakes to avoid with frameworks
- Applying them mechanically: the framework is the structure, not the text. If it feels like a cage, rewrite it.
- Neglecting the offer: no framework saves a weak offer. Offer first, copy second.
- Stacking multiple CTAs: one step per message; two invitations cancel each other out.
- Making up numbers: in the agitation and desire steps, use real data. In B2B, trust is the asset, and an inflated number burns it.
- Not testing: pick the framework based on your hypothesis, then let the data decide.

In summary
AIDA to open a cold relationship, PAS to push those who already feel the problem, BAB to sell a transformation. Don't treat them as dogma: use them as scaffolding to write faster and with more structure, then refine with testing. As volume grows, hand off the first draft to an AI that knows your voice, and stay the editor who decides. For the full picture, start with our guide to copywriting for customer acquisition.
Frequently asked questions
What is the best copywriting framework?
There isn't an absolute best: it depends on how aware the customer is of the problem and on the channel. AIDA for cold outreach, PAS when the problem is already felt, BAB when you're selling a transformation. They're often combined in sequence.
What's the difference between AIDA and PAS?
AIDA builds interest from scratch in four stages (Attention, Interest, Desire, Action) and suits a cold audience. PAS starts from the problem and agitates it before offering the solution: it's more direct and generally more effective for direct response.
What does BAB mean in copywriting?
BAB stands for Before, After, Bridge: you describe the customer's current situation, then the desired outcome, and finally how your product bridges the two. It's ideal for landing pages, nurturing and case studies.
Can I use AI to write with these frameworks?
Yes. Give the AI the explicit framework, the product context and your brand voice, ask for multiple variations, then edit. You get a first draft in minutes instead of hours, while keeping final control over the copy.
Which framework should I use for B2B cold emails?
Usually PAS, because the recipient often recognizes the problem from the first line. If the audience is colder or less aware, AIDA helps build interest and desire first.
Do these frameworks also work for landing pages?
Yes. BAB works well in the hero section (the transformation), AIDA in long cold landing pages, and PAS in sections that handle objections and drive action.
