Treat AI like a junior copywriter. Your prompt is the brief.
Bad prompt:
“Write an ad for running shoes.”
Great prompt:
“Write 3 Facebook ads for a $100 lightweight running shoe. Target 30–45-year-old men training for their first marathon. Focus on comfort and foot support.”
Want even better results? Include examples of your brand voice or high-performing past ads in your prompt.

Take your highest-converting past ads and use this prompt:
“Analyze this ad and describe the tone, structure, and messaging style.”

Use AI to test:
Each micro-copy variation can influence performance. Use ad analytics to test results, then feed high-performers back into your AI prompts to scale what works.
Even if your copy is 90% AI-generated, the last 10% must be human-edited. Look out for:
Read it aloud. Does it sound like a person wrote it? If not—edit until it does.

AI can accelerate the ad copywriting process, but it can’t replace human instinct, brand knowledge, or strategic thinking. It’s a tool—not a shortcut.
