What is a Persona? How to build yours

A persona is the semi-fictional and detailed representation of the ideal customer, based on real data and interviews. It goes far beyond a target audience: it includes name, age, profession, pains, goals, habits and cultural references. It serves as a compass for content, copy, offers and media channel decisions.

What is a Persona?

Persona (or buyer persona) is the detailed and humanized representation of a business's ideal customer. Unlike target audience, which is generic and demographic (e.g., "women 25-45, AB class, São Paulo"), a persona has a name, profession, specific pains, goals, behaviors and even cultural references.

The purpose is simple: when everyone on the team knows who they're talking to, decisions become faster and more aligned.

What a persona should contain

Fictional name (humanizes)
Age, gender, location
Profession and income
Lifestyle and routine
Personal and professional goals
Pains and frustrations (especially those your product solves)
Common purchase objections
Preferred media channels (Instagram? TikTok? LinkedIn?)
Brands she admires
How she researches before buying
Typical quote (something she would say)

How to build one

Look at your current customer base: who are the top 20%?
Interview 8 to 12 people from that base (30 to 45 minutes each)
Analyze network data (Instagram Insights, Meta Business)
Identify patterns (profile, pains, recurring objections)
Write the persona on 1 visual page
Validate with the sales and service team

Larger businesses may have 2 to 4 personas. More than that gets confusing.

Practical example

Persona — Marina, the Tired Entrepreneur

34, married, 1 child aged 5
Lives in Curitiba, middle class
Co-owner of a bakery with 8 employees
Household income: R$ 18k
Routine: opens the shop at 7am, leaves at 7pm, picks her child up at school
Goals: scale to 2 shops; have more time with family
Pains: can't handle marketing alone; tried 2 agencies, both bad; afraid of not knowing what to measure
Objections: "I'll lose control if I delegate"; "I don't have R$ 5k/month"
Channels: Instagram, WhatsApp, occasionally LinkedIn
Typical quote: "I just want to grow without losing sleep"

With this persona defined, it becomes easy to decide:

Captions use her words ("without losing sleep", "tight routine")
Reels show the busy entrepreneur routine
Offer highlights a dashboard with "5 minutes a day"
Media in Reels and Stories before 9am and after 9pm

Persona vs Target audience

Target audience: "Women 30-45, AB class, small-business owners in SP, RJ and PR"
Persona: Marina (above)

The target audience drives media targeting. The persona drives every other decision.

Common mistakes

Inventing a persona without data ("I think it's like this")
Creating 8 personas (becomes unusable)
Persona with no concrete pain — says nothing
Not sharing with the whole team
Not revisiting every 12 months (market changes, persona changes)
