What is a copywriting formula

A copywriting formula is a proven writing structure that helps you deliver a message in a way that drives action. It's not a "template" — it's a skeleton you build your message around. Here are the 5 best formulas for Facebook posts.

The AIDA formula

Attention → Interest → Desire → Action. This is the classic. First you grab attention, then you build interest, create desire, and finally call the reader to act.

ℹ️
Example: "Stop scrolling! (Attention) Did you know 500 businesses just switched to automated posting? (Interest) Picture your business advertised in 100 Groups — without typing a single word (Desire). Click here for a free trial (Action)."

The PAS formula

Problem → Agitate → Solve. You surface a problem, amplify it (make it sting), and then offer the solution. Works remarkably well in B2B marketing.

ℹ️
Example: "Spent an hour and a half posting to Groups today? (Problem) And you still haven't reached half the relevant ones, while a competitor already beat you to it (Agitate). Natural Poster does it in one click (Solve)."

The BAB formula

Before → After → Bridge. Show the current state (before), the dream state (after), and how to get from one to the other (bridge).

ℹ️
Example: "Before: spending 5 hours a day on manual posting (Before). After: posts go live automatically, and I only focus on customers (After). How? Natural Poster (Bridge)."

The FAB formula

Features → Advantages → Benefits. Spell out the features, connect them to advantages, and show the personal benefit to the customer.

The 4U formula

Useful, Urgent, Unique, Ultra-specific. The perfect headline hits all four — useful, urgent, unique, and specific.

💡
Example: "Save 23 hours a week on Facebook posting — 47 local businesses already swear by it. End-of-month deal: 3 days free."

Which formula should you use?

  • AIDA — for general posts, broad marketing
  • PAS — for B2B posts, business audiences
  • BAB — for success stories and transformations
  • FAB — for posts about a specific product
  • 4U — for headlines and CTAs
