Staring at a blank page is the most expensive part of writing marketing copy. You know your product is good, you know who it is for, but the first sentence will not come. Copywriting formulas solve that problem. They are simple, proven structures that tell you what to say first, what to say next and where to ask for the sale.
Formulas are not templates you fill in mechanically. They are a way of ordering an argument so it follows how people actually make decisions: notice something, care about it, believe it, act on it. Used well, they make copy clearer and faster to write. Used badly, they produce the same tired, hype-filled copy everyone scrolls past.
In this guide you will learn the copywriting formulas that still work in 2026 – AIDA, PAS, BAB, FAB, the 4Ps, the 4Us and a few others – with examples for ads, landing pages, emails and social posts, a step-by-step process for choosing the right one, and the mistakes that make formula-driven copy fall flat.
Key Takeaways
- A copywriting formula is a structure for ordering your message, not a script to copy word for word.
- AIDA and PAS cover most situations: AIDA for building interest, PAS for audiences who already feel a problem.
- Choose the formula based on how aware your reader is of their problem and of your solution.
- Readers on the web scan, so formula-driven copy still needs short sentences, clear headings and concrete specifics.
- Every claim in persuasive copy must be true and provable – the FTC requires evidence before an ad runs.
What is a copywriting formula?
A copywriting formula is a repeatable sequence of persuasive steps. Each letter in an acronym like AIDA or PAS stands for a job that a section of your copy has to do. The formula does not tell you which words to use; it tells you which job comes next.
Formulas exist because the psychology of persuasion is fairly stable. People need to notice your message, see why it matters to them, trust that you can deliver and know exactly what to do next. A formula simply makes sure none of those steps is skipped.
They are especially useful when you write across many formats. The same PAS structure can shape a 30-character search ad headline, a three-line social caption and a full sales page. That consistency helps a team write faster and helps a brand sound coherent across channels.
The copywriting formulas worth knowing
| Formula | Stands for | Best for | Watch out for |
|---|---|---|---|
| AIDA | Attention, Interest, Desire, Action | Landing pages, video scripts, display ads | Weak “Interest” sections that jump straight to the pitch |
| PAS | Problem, Agitate, Solution | Emails, search ads, service pages | Over-agitating until the copy feels manipulative |
| BAB | Before, After, Bridge | Social posts, case studies, testimonials | An “After” that promises results you cannot prove |
| FAB | Features, Advantages, Benefits | Product pages, spec sheets, B2B sales copy | Listing features without ever reaching the benefit |
| 4Ps | Promise, Picture, Proof, Push | Long-form sales pages, webinars | Thin or vague “Proof” |
| 4Us | Useful, Urgent, Unique, Ultra-specific | Headlines, subject lines, ad headlines | Fake urgency (“only today!” every day) |
| QUEST | Qualify, Understand, Educate, Stimulate, Transition | Consultative B2B services | Taking too long to get to the point |
| ACCA | Awareness, Comprehension, Conviction, Action | Complex or technical products | Too much education, not enough conviction |
AIDA: Attention, Interest, Desire, Action
AIDA is the classic. Open with something that earns attention (a sharp headline, a surprising fact, a bold visual), build interest with information the reader cares about, create desire by showing how life improves, and end with a single clear action.
Example (local plumber landing page): “Burst pipe at 2 a.m.? (Attention) We answer the phone 24/7 and arrive within the hour across the city. (Interest) Licensed engineers, fixed upfront prices, and a tidy home when we leave. (Desire) Call now for a free quote. (Action)”
PAS: Problem, Agitate, Solution
PAS starts where the reader already is: with a problem. You then agitate it – show the cost of leaving it unsolved – before presenting your solution. It is one of the most effective formulas for emails and search ads because the searcher has usually typed the problem into the search bar.
Example (SEO service email): “Your website traffic has flatlined. Every month competitors publish more, rank higher and take the enquiries that used to be yours. Our SEO service finds the pages holding you back and fixes them first.”
BAB: Before, After, Bridge
BAB paints the current situation, then a better future, then shows your product as the bridge between them. It suits social media and case studies because it naturally tells a story with a transformation in the middle.
FAB: Features, Advantages, Benefits
FAB forces you to translate product details into outcomes. A feature is what it is (“16-hour battery”), an advantage is what it does (“lasts a full working day”), and the benefit is why the buyer cares (“no more hunting for a socket before your afternoon meeting”). It is ideal for product pages, where shoppers compare specifications.
4Ps: Promise, Picture, Proof, Push
The 4Ps make a promise, help the reader picture the result, back it up with proof such as reviews, data or a marketing case study, and finally push them to act. The proof step is what separates this from hype, so do not skip it.
4Us for headlines
The 4Us – useful, urgent, unique, ultra-specific – are a checklist rather than a sequence. Test a headline or email subject line against all four. “How to Cut Your Google Ads Cost per Lead by Fixing 3 Settings This Week” scores well; “Improve Your Ads” scores poorly on every U.
Why formulas still need web-friendly writing
A formula fixes the order of your argument, but it does not fix how people read online. Usability research has shown for decades that web readers skim rather than read line by line.
“People rarely read Web pages word by word.”
— Nielsen Norman Group, How Users Read on the Web
The same Nielsen Norman Group study found that promotional, boastful language made pages harder to use, while concise, scannable and objective writing made them easier. That is a warning for formula users: “Agitate” and “Desire” do not mean exaggerate. They mean make the problem and the benefit concrete.
In practice this means:
- Put the most important point of each formula step in the first sentence of its paragraph.
- Use subheadings so a scanner can follow the formula from top to bottom.
- Replace adjectives with specifics: numbers you can prove, timeframes, names of real customers (with permission).
- Keep one call to action per piece, and make the button text describe what happens next.
How to choose and use a copywriting formula: step by step
- Define the single goal. Decide the one action you want: a call, a sign-up, a purchase, a reply. Formulas fall apart when copy tries to do three things.
- Know your reader. Write down who they are, what they want and what worries them. A buyer persona makes this faster and keeps the whole team aligned.
- Judge awareness. Is the reader unaware of the problem, aware of the problem, or comparing solutions? Unaware readers need AIDA or ACCA; problem-aware readers respond to PAS; solution-aware readers want FAB and proof.
- Match the formula to the channel. Short formats (ads, captions, subject lines) suit PAS, BAB and the 4Us. Long formats (sales pages, webinars) suit AIDA and the 4Ps.
- Collect proof before you write. Gather reviews, results, guarantees and data. You will need them for the Desire, Proof or Bridge step, and the FTC expects advertisers to have evidence for claims before the ad runs.
- Draft quickly, step by step. Write one or two sentences for each letter of the formula. Do not polish yet.
- Edit for clarity and honesty. Cut filler, replace vague adjectives, check every claim, and read it aloud.
- Test and measure. Run A/B tests on headlines and calls to action, and track results through your conversion rate optimisation process rather than relying on opinion.
Which formula for which channel?
| Channel | Recommended formula | Practical constraint |
|---|---|---|
| Google search ads | PAS or 4Us across headlines | Responsive search ads allow up to 15 headlines of 30 characters and 4 descriptions of 90 characters |
| Meta and social ads | BAB or PAS | The first line must stop the scroll; see our Facebook ads guide |
| Landing pages | AIDA or 4Ps | One goal, proof above the fold; read our guide to PPC landing pages |
| PAS for body, 4Us for subject line | Subject lines are truncated on mobile, so front-load meaning | |
| Product pages | FAB | Shoppers compare specs; translate each into a benefit |
| Title tags and meta descriptions | 4Us (simplified) | Space is short; follow our guides to title tags and meta descriptions |
Google’s own advice for responsive search ads is to give the system plenty of distinct options, so it can combine them. That fits formula thinking nicely: write several headlines for each step (a problem headline, a solution headline, a proof headline) rather than ten versions of the same sentence.
Using formulas in SEO content
Formulas are built for persuasion, while most SEO content exists to answer a question. Mixing the two works if you are deliberate about it. Use a formula for the introduction (PAS works well: state the problem the searcher has, show why it matters, promise the answer), for calls to action and for any commercial page. Then switch to a clear informational structure for the body, guided by search intent.
Our guides to writing a blog post and SEO content writing show how to combine persuasive openings with content that genuinely answers the query. For email sequences, the same thinking applies; see our email marketing best practices.
Common mistakes with copywriting formulas
- Filling in the boxes mechanically. Readers can sense a template. Use the formula to plan, then write like a person.
- Agitating too hard. Fear-based copy can backfire and damage trust. Describe real consequences, not catastrophes.
- Making claims you cannot prove. The FTC says advertising must be truthful and non-deceptive, and that advertisers need evidence to back up claims. Fake scarcity and invented results are risky as well as ineffective.
- Using one formula for everything. A cold audience and a returning customer need different structures.
- Forgetting the action. Many drafts build interest beautifully and then end with a vague “learn more”. Be specific about the next step.
- Never testing. A formula is a hypothesis about your audience. Test headlines and calls to action and let the data decide.

Frequently Asked Questions
What is the most popular copywriting formula?
AIDA (Attention, Interest, Desire, Action) is the best known and the most widely taught. It works for almost any format, from a landing page to a short video script, which is why it is a good default when you are unsure which formula to use.
What is the difference between AIDA and PAS?
AIDA starts by grabbing attention and builds desire for a positive outcome. PAS starts with a problem the reader already feels, makes the cost of that problem clear, and then offers the solution. PAS is usually stronger when your audience is actively frustrated; AIDA suits broader awareness messages.
Do copywriting formulas work for SEO content?
Partly. Formulas help with introductions, calls to action, title tags and meta descriptions. But long-form SEO content must answer the searcher’s question thoroughly, so use a formula for the persuasive parts and a clear informational structure for the rest.
Can I use AI tools with copywriting formulas?
Yes. Asking an AI tool for a draft “using PAS” or “using BAB” often produces a more structured first version. Always edit the output: check every claim is accurate, add real proof such as customer results, and make the voice sound like your brand.
How long should copy written with a formula be?
As long as it needs to be for the reader to make a decision. A search ad might use a formula across 30-character headlines, while a landing page for an expensive service may need several screens. The formula sets the order; the audience sets the length.
Conclusion
Copywriting formulas are shortcuts to clear, persuasive structure. Start with AIDA and PAS, add BAB, FAB and the 4Ps as your confidence grows, and always pair the formula with honest proof and web-friendly writing. Then test, because your audience – not the acronym – has the final say.
