AI-Powered Product Briefs & Buyer Personas for Better Meta Ads

Every great Meta campaign starts before you open Ads Manager.

If your creative or copy feels “off,” it’s often because you skipped the most important prep work:

- Knowing your product inside out

- Knowing exactly who you’re selling to

In this issue of Digital Ad Snack, you’ll learn how to use AI to quickly build two powerful ad supporting documents:

• A product brief so you know exactly what you’re selling and how to position it.

• A buyer persona so you know exactly who you’re talking to and what makes them buy.

Once you have these, you’ll never start a campaign guessing again and Meta’s algorithm will have the signals it needs to find your best buyers.

Build Your Product Brief

You can’t create scroll-stopping ads or write hooks that make people click... unless you truly understand what you’re selling.

This is where most advertisers go wrong.

They rush into Ads Manager, skip the groundwork, and end up with generic messaging that could fit any product.

A winning Meta Ads campaign starts with a crystal-clear product brief.

It starts with a research document that outlines your offer’s features, benefits, objections, and angles.

The good news? You don't need to to this research manually.

With the right prompt, AI can build a draft for you in minutes.

Here’s the prompt I use:

Example for a Liverpool T-shirt product:

The prompt is just the starting point.

Always refine the output until you’re satisfied.

Don’t be lazy, don’t just paste your product link and call it a day.

Feed AI the information you’ve gathered from customer reviews, competitor websites, sales calls, client (if you are a media buyer), and your own expertise.

The richer the input, the sharper the output.

Feed AI the information you’ve gathered from:

• Customer reviews

• Competitor websites

• Client insights (if you’re a media buyer)

• Your own expertise

The richer the input, the sharper the output.

When done right, your product brief becomes your campaign blueprint.

It tells you:

• What to highlight (core features and benefits)

• How to position the product

• Which objections to overcome in your copy

• What unique angles to test in creative

💡 Pro Tip: Treat your product brief as a living document. Update it as your offer evolves, you test new hooks, or customer feedback shifts.

Build Your Buyer Personas

Once you know your product inside and out, the next step is knowing exactly who you’re selling to.

A buyer persona is more than just “25–40 year-old women who live in cities.”

It’s a detailed profile of your ideal customer:

their pain points, goals, habits, objections, and emotional triggers.

I usually give them names, AI likes to give names also.

The clearer you are on who you’re speaking to, the easier it is to craft copy and creative that makes them pay attention.

Here’s the AI prompt to create yours:

Example for creating buyer personas:

Just like with your product brief, don’t take the first draft and run with it.

Review the output and refine it with real-world insights from:

• Customer feedback and reviews

• Sales team notes

• Social media comments

• Competitor audience analysis

The goal is to make your personas feel like real people you could talk to because, in your ads, you will be talking directly to them.

When done right, these personas become your creative compass.

They’ll guide your hook ideas, dictate your tone, and help Meta’s algorithm connect your ads with the people most likely to buy.

💡 Pro Tip: Revisit your personas regularly. As your offer and market change, so will your ideal customers.

This Is How You Stop Guessing and Start Converting

Great Meta Ads don’t start with the “publish” button.

They start with a clear understanding of your product and your ideal customer.

Your product brief gives you the foundation.

Your buyer personas give you the direction.

Together, they give you, and Meta’s algorithm, the exact signals needed to connect with the right audience.

Once you got this covered you can go on and write your personalized copy and hooks for each product and buyer persona. (But this topic is for another DAS issue.)
