Copywriting Formulas That Sell: AIDA, PAS and More

Copywriting formulas are proven structures that organise persuasive writing so it converts. The most useful are AIDA (Attention, Interest, Desire, Action), PAS (Problem, Agitate, Solution) and FAB (Features, Advantages, Benefits). They work because they follow how people make decisions: grabbing attention, building relevance and desire, and prompting action. Using a formula gives your copy a reliable backbone instead of leaving persuasion to chance.

Proven copywriting formulas like AIDA and PAS explained with examples, and how South African businesses can use them to write copy that converts.

TL;DR: Quick Answer

Basic South African brochure sites: R8,000-R20,000. Custom business websites with SEO and copywriting: R20,000-R50,000. E-commerce: R40,000-R150,000+. The five cost drivers that create the biggest price variation are: scope and number of pages, custom vs template design, professional copywriting, integrations (payment gateways, booking systems, CRM), and on-page SEO included at build stage. Always add 15-25% for hosting, maintenance and content updates in year one.

Key takeaways

  • Very cheap quotes (under R5,000) almost always exclude copywriting, SEO, custom design and post-launch support
  • Professional copywriting can represent 20-35% of a total website project cost, and is worth it for search visibility
  • On-page SEO built into the website at launch costs a fraction of what it costs to retrofit after the site is live
  • Hosting, SSL, domain and maintenance add R3,000-R10,000 per year on top of build cost
  • E-commerce adds significant cost due to payment gateway integrations, product data, security requirements and checkout UX
  • Timeline and client responsiveness directly affect cost: slow feedback rounds extend agency hours

Summary

Good copy is not magic; it follows structures that have been proven to persuade. Copywriting formulas give you a reliable framework so you are not staring at a blank page hoping inspiration strikes. This guide explains the most useful formulas, AIDA, PAS, FAB and a few others, with plain examples, and shows South African businesses how to apply them to ads, emails, landing pages and product descriptions that actually convert.

Why formulas work

Copywriting formulas distil decades of what persuades people into repeatable structures. They work because they mirror how people actually make decisions: you have to catch attention before anything else, make the message relevant, build desire, and then prompt action. A formula ensures your copy hits these beats in the right order, rather than rambling or selling before the reader cares. They are not creative straitjackets; they are scaffolding that makes good writing faster and more reliable.

AIDA: Attention, Interest, Desire, Action

The classic, and a great default for ads, landing pages and emails:

  • Attention: open with a hook, a bold statement, a question, a striking benefit, that stops the reader.
  • Interest: build relevance by speaking to something the reader cares about.
  • Desire: make them want it, through benefits, proof and a vision of the better outcome.
  • Action: tell them exactly what to do next, clearly and with a reason to act now.

Use AIDA when: You need a complete persuasive arc in one piece, an ad, a sales email, a landing page. It carries the reader from cold to converted.

PAS: Problem, Agitate, Solution

Powerful when your audience has a clear pain point:

  • Problem: name the problem the reader is experiencing, so they feel understood
  • Agitate: explore the problem and its consequences, making the reader feel the cost of inaction
  • Solution: present your product or service as the relief

PAS converts well because it taps the strong motivation to escape a problem. Used honestly, it shows empathy and offers genuine help; used manipulatively, it manufactures anxiety, so apply it with integrity.

FAB: Features, Advantages, Benefits

Essential for product copy, because it stops you listing specs nobody cares about:

  • Feature: what it is or has (the factual attribute).
  • Advantage: what the feature does (why it matters technically).
  • Benefit: what it means for the customer (the real-world payoff they care about).

The discipline of FAB is always translating features into benefits. Customers do not buy a feature; they buy what it does for them. 'Five-year warranty' (feature) becomes 'peace of mind that you are covered for years' (benefit).

A few more worth knowing

  • 4 Ps (Promise, Picture, Proof, Push): promise a benefit, paint the picture, prove it, then push for action
  • BAB (Before, After, Bridge): show life before, the better after, and your offer as the bridge between
  • The 4 Us (Useful, Urgent, Unique, Ultra-specific): a checklist for sharpening headlines

How to actually use them

Formulas are starting structures, not rigid scripts. Choose the one that fits the job, AIDA for a full sales piece, PAS for a pain-driven audience, FAB for product copy, draft within it, then edit so it reads naturally in your brand voice. The formula gives you the bones; your voice and your customer knowledge give it life. Over time you will internalise them and apply them almost without thinking, which is exactly when your copy gets reliably good.

Frequently asked questions

What are copywriting formulas?

Copywriting formulas are proven structures that organise persuasive writing so it converts. They mirror how people make decisions, catching attention, building relevance and desire, and prompting action, giving your copy a reliable backbone instead of leaving persuasion to chance.

What is the AIDA formula?

AIDA stands for Attention, Interest, Desire, Action. You open with a hook to grab attention, build interest by speaking to what the reader cares about, create desire with benefits and proof, then prompt a clear action. It suits ads, emails and landing pages.

What is the PAS copywriting formula?

PAS stands for Problem, Agitate, Solution. You name the reader's problem so they feel understood, explore its consequences to make the cost of inaction felt, then present your product as the relief. It works well when the audience has a clear pain point.

What is the difference between features and benefits?

A feature is what a product is or has; a benefit is what that means for the customer in real life. The FAB formula translates each feature into the advantage it provides and the benefit the customer cares about, because customers buy outcomes, not specs.

Which copywriting formula should I use?

Choose by the job: AIDA for a complete sales piece like an ad or landing page, PAS for an audience with a clear pain point, and FAB for product copy. Use the formula as a starting structure, then edit so it reads naturally in your brand voice.

Do copywriting formulas make writing sound formulaic?

Not if used well. Formulas are scaffolding, not scripts. You draft within the structure to ensure your copy hits the right persuasive beats, then edit so it reads naturally in your own voice. The formula gives the bones; your voice gives it life.
