Copywriting formulas get a mixed reception. Some writers love them as reliable scaffolding. Others dismiss them as constraints that produce mechanical, soulless copy.
The truth is somewhere in the middle. Formulas are frameworks, not cages. They reflect accumulated wisdom about how readers process information and make decisions. Used well, they give you a structure that works while leaving plenty of room for voice, specificity, and craft.
The key is knowing which formula to use when — and understanding each one deeply enough to apply it flexibly rather than mechanically.
AIDA: The Classic Framework
AIDA stands for Attention, Interest, Desire, Action. It’s been in use since the 1890s, and the reason it endures is simple: it maps to how people actually move from not knowing about something to taking action on it.
Attention — Stop the reader. Your headline, subject line, or opening image needs to interrupt whatever your reader was doing and pull them in. This is where most copy fails. Weak attention doesn’t get read.
Good attention-getters:
- Name a specific problem your reader has
- Make a bold, specific claim
- Ask a question that hits a nerve
- Reveal something surprising or counterintuitive
Example: “Why Most Freelancers Are Leaving 40% of Their Income on the Table”
Interest — Hold them once you’ve got them. After the attention-grabber, you need to expand on why this matters to your reader specifically. Agitate their situation. Show them you understand the problem with precision.
Example: “You’re probably undercharging. Not by 5% or 10% — by nearly half. Most freelancers set rates based on what feels comfortable to ask for rather than what the market will actually pay. And they never find out the difference.”
Desire — Make them want what you’re offering. This is where you pivot from the problem to the solution. Benefits, not features. What will their life or work look like with this problem solved? Use testimonials, case studies, and specifics to build credibility.
Action — Tell them exactly what to do next. One clear, specific instruction. Remove any friction or ambiguity. “Start your free trial today — no credit card required” is better than “Learn more.”
When to use AIDA: Email campaigns, sales pages, landing pages, advertising copy — any format where you’re taking someone from cold interest to conversion.
PAS: Problem, Agitate, Solution
PAS is arguably even more widely applicable than AIDA for short-form copy. It’s a three-step formula built around a deep truth: people are more motivated to escape pain than to pursue gain.
Problem — State the problem clearly and specifically. Don’t dance around it.
Example: “Writing consistently is the hardest part of building an audience.”
Agitate — Make the problem feel bigger and more urgent. Describe the downstream consequences. This isn’t about being cruel — it’s about helping the reader recognize how much the problem is already costing them.
Example: “Every week you don’t publish, your audience stagnates. Every month of inconsistency, your authority erodes. Competitors who show up consistently take the readers and clients you could have had.”
Solution — Now introduce your offer as the clear, credible solution to the problem you’ve agitated.
Example: “Content Calendar Pro gives you 90 days of pre-planned topics, batch writing templates, and a scheduling system that makes consistency automatic — even on your busiest weeks.”
When to use PAS: Email subject lines, short ad copy, social media posts, blog introductions, cold outreach. It’s versatile and fast to write. PAS is particularly effective in email copywriting where you need to hook someone in the first two lines.
FAB: Features, Advantages, Benefits
FAB helps you translate technical product information into reader-relevant value. It’s less a structural template and more a way of thinking through your message before you write it.
Features — What does the product actually do or have? Objective specifications.
Example: “Our app includes 200+ pre-built workflow templates.”
Advantages — What does that feature give users? The functional advantage over the alternative.
Example: “You don’t have to build processes from scratch — you start with proven frameworks.”
Benefits — What does that advantage mean for the user’s life or work?
Example: “You’ll launch your new project system in an afternoon instead of spending weeks designing workflows you’re not sure will work.”
Most marketers stop at features. Some get to advantages. The best copywriters always make it to benefits.
When to use FAB: Product descriptions, feature highlight sections on landing pages, B2B sales copy where technical details matter but still need to be translated into business value.
The 4Ps: Promise, Picture, Proof, Push
The 4Ps formula is particularly powerful for long-form sales copy and direct response.
Promise — Lead with the core benefit you’re promising. Be specific and bold.
Example: “Double your email open rates in 30 days or we’ll refund your subscription.”
Picture — Paint a vivid picture of life with the promise fulfilled. Help the reader see themselves in that scenario. The more concrete and sensory, the better.
Example: “Imagine checking your email stats on a Thursday morning and seeing 48% open rates where you used to see 22%. Your campaigns are getting the attention they deserve. Revenue is up. Your boss is asking what changed.”
Proof — Provide evidence. Testimonials, data, case studies, expert endorsements, before/after results.
Push — Create urgency and drive the action. Why should they act now rather than later?
When to use the 4Ps: Long-form sales pages, direct mail, video sales letters, pitches to decision-makers.
BAB: Before, After, Bridge
BAB is a storytelling formula that works by contrasting a reader’s current painful situation with a future transformed one, then presenting your offer as the bridge between the two.
Before — Describe the reader’s current situation in vivid, relatable terms.
Example: “You’re spending four hours every week writing social media content, and the engagement you’re getting barely justifies the time.”
After — Describe the better reality on the other side.
Example: “What if you could produce a month’s worth of content in a single afternoon — and have it perform better than anything you’ve been grinding out manually?”
After — Present your product or service as the path from Before to After.
Example: “ContentBatch’s AI-assisted templates and scheduling system make it possible. Users typically cut their content creation time by 70% in the first month.”
When to use BAB: Case studies, testimonials (structure client stories this way), landing page opening sections, social media ads, before-and-after success stories.
Choosing the Right Formula
The formula you choose should match the format and the reader’s state of awareness.
If your reader doesn’t yet know they have the problem → Use PAS to reveal and agitate the pain first.
If your reader knows the problem but hasn’t considered your solution → Use AIDA to move from attention through desire.
If you’re writing about a product with real technical depth → Use FAB to translate features into value.
If you’re writing long-form sales copy → Use the 4Ps as your structural backbone.
If you’re telling a transformation story → Use BAB to make it relatable and compelling.
You can also combine formulas. Many effective sales pages use BAB in the opening section, FAB in the features section, and close with the 4Ps’ “Push” to drive urgency.
Applying Formulas Without Sounding Formulaic
The reason formulas get a bad reputation is that inexperienced copywriters apply them too rigidly. The structure becomes visible, and visible structure breaks immersion.
The solution is to learn the formulas deeply enough that they inform your writing rather than dictate it. When you understand why PAS works — that people are motivated by pain and relief — you can apply that psychological insight flexibly without robotically following a three-step template.
Great copy feels natural and reads easily. The structure underneath it should be invisible. That’s the standard to aim for.
And once you’re comfortable with formulas, the next level is applying them to specific formats. Our guide on landing page copywriting best practices that boost conversions shows exactly how these frameworks come to life in one of the highest-stakes copywriting contexts.
