How to Write Facebook Ad Copy That Sells: 7 Formulas for Small Businesses
Staring at an empty text box is the hardest part of writing an ad. The good news: professional copywriters rarely start from zero. They use formulas — simple structures that have worked for decades. Here are seven you can use today, each with an example you can adapt.
Before you start: three things to know
- Who the ad is for — one specific type of customer.
- What problem they have and what result they want.
- What you want them to do — message you, book, buy, visit.
Write those three lines down first. Every formula below is just a way to arrange them.
1. PAS — Problem, Agitate, Solution
Name the problem, make the reader feel it, then offer the fix. It works because people act faster to avoid pain than to gain something new.
Problem: Your back hurts after a day at the desk?
Agitate: It gets worse every week, and painkillers only hide it.
Solution: Our 30-minute posture sessions target the cause. First session is free — send us a message to book.
2. AIDA — Attention, Interest, Desire, Action
The classic. Grab attention, build interest with a detail, create desire with a benefit, finish with a clear action.

3. Before – After – Bridge
Show life before, show life after, and present your product as the bridge between them.
Before: Spending Sunday evenings trying to plan the week's meals?
After: Imagine opening the fridge and knowing exactly what to cook, every day.
Bridge: Our weekly meal plans do the thinking for you — with a shopping list included.
4. The direct offer
Sometimes the best ad is simply a good offer, stated clearly. This works especially well for local businesses and returning customers.
New clients: first haircut −30% until Sunday.
No appointment needed on weekdays before 2 p.m.
📍 12 Main Street · Tap “Send message” to book your slot.
Tip: a deadline (“until Sunday”) or a limit (“first 20 clients”) gives people a reason to act now instead of “later” — which usually means never.
5. The question hook
Open with a question your ideal customer would answer “yes” to. It makes them self-select: the right people keep reading.

6. Social proof first
Lead with what customers say or with a result. People trust other customers more than they trust brands.

Only use real reviews and real results. Invented testimonials damage trust, and they can break advertising rules.
7. The 4 U's — Useful, Urgent, Unique, Ultra-specific
Use this one as a checklist for your headline. The more of the four U's it hits, the stronger it is.
- Weak: “Quality car detailing.”
- Strong: “Full interior detailing in 3 hours — this week only €79, pick-up from your office included.”

- Talking about yourself. “We are a team of passionate professionals” says nothing to the customer. Talk about their result.
- More than one call to action. “Call us, visit the site, follow us and share” means nobody does anything.
- Vague benefits. “High quality” and “best service” are claimed by everyone. Be specific: numbers, time, what's included.
- A long first line. Only the beginning of your text is visible before “See more”. Put the hook there.
- Never testing. Write two or three versions with different hooks and let the results decide.
How to choose the right formula
If your customer has a clear pain, start with PAS or Before–After–Bridge. If you have a strong offer, use the direct offer. If you have great reviews, lead with social proof. When in doubt, write the same ad with two different formulas and compare the results — your audience will tell you which one works.
