Structure Every Ad Around the Hook
The first two lines of your primary text determine whether someone stops scrolling. Lead with curiosity, a bold promise, or a specific pain point your audience recognizes. From there, explain the benefit in plain language and finish with a direct CTA like "Learn More" or "Shop Now."
Primary Text, Headlines, and Description
Use the primary text to build interest, the headline to reinforce the offer, and the description to add urgency or context. Each field has a different role:
- Primary text: The main story or promise.
- Headline: Short, high-impact reinforcement.
- Description: Extra detail or a time-sensitive nudge.
Frameworks That Work
Several proven frameworks help structure concise, persuasive copy:
- PAS: Problem, Agitation, Solution.
- BAB: Before, After, Bridge.
- AIDA: Attention, Interest, Desire, Action.
Choose the one that matches your funnel stage and keep the language conversational and specific.
Best Practices and Common Mistakes
Match your copy to the placement, keep sentences short, and test one variable at a time. Avoid vague claims, excessive punctuation, and jargon that doesn't resonate with your target audience.
Testing and Iteration
Run small experiments with different hooks, CTAs, and audience segments. Use Facebook's split-testing tools to let performance data guide which copy variations you scale.
