A customer persona is a short profile of a typical buyer: who they are, what they want, what worries them and what makes them buy. In advertising, it tells you who an ad speaks to and what the ad should say.

## What goes in a persona

| Field | Question it answers |
|---|---|
| Who | Age, city, job, who they live with |
| Goal | What do they want to change? |
| Problem | What is stopping them today? |
| Objection | Why might they not buy from you? |
| Trigger | What makes them buy now? |
| Words | How do they describe it themselves? |

## A worked example

Say you sell protein powder. This persona is made up to show the shape.

- **Who:** Rohit, 27, software tester in Pune, goes to the gym four days a week.
- **Goal:** Add muscle without a trainer's diet plan.
- **Problem:** Cannot tell which brands are real.
- **Objection:** "Is it fake? Is it safe?"
- **Trigger:** A friend's recommendation, or a lab report.
- **Words:** "clean", "no fillers", "value for money".

The ad nearly writes itself. Example hook we wrote: "How to check if your protein powder is real." Then the ad shows the lab report for the batch.

## Build one from real data, not guesses

1. Pull 50 to 100 comments, reviews and DMs.
2. Group them by goal and objection. Count each group.
3. Talk to five buyers. Use the [customer interview script](/templates/customer-interview-script-for-ad-research).
4. Fill one page with the [persona template](/templates/persona-template-for-ad-teams).
5. Write one ad per persona and see which gets cheaper purchases.

## Common mistakes

- Inventing a persona from your own taste.
- Making ten personas. Start with two or three.
- Describing demographics only. "Women 25 to 34" does not tell you what to say.

Pair each persona with an [ad angle](/glossary/ad-angle) and an [awareness level](/glossary/awareness-levels). List their [customer objections](/glossary/customer-objections) on the same page.

Marxx builds personas from comments and reviews (we make Marxx). See [audience personas](/features/audience-personas).

## FAQ

### Is a persona the same as a target audience?

No. A target audience is a group you pick in Ads Manager, such as women in Pune aged 25 to 34. A persona describes one person in that group, in words you can write ads for.

### How many personas do I need?

Two or three is enough for most brands. Add another only when it needs a different message.

### How often should I update a persona?

Review it every quarter, or sooner when new comments and reviews show a different pattern.
