The essentials
- Definition: a persona is the archetypal portrait of a customer segment, built from interviews and real data, serving as a shared reference for marketing decisions.
- Useful: the problem to solve, the trigger to buy, the decision criteria, the objections, the sources of information, the role in the decision.
- Useless: an invented first name, a stock photo, hobbies, the make of car; those details have never changed a marketing decision.
- The rule: two to four personas at most, built on ten to fifteen customer interviews, reviewed each year.
A persona is the archetypal portrait of a customer segment, built from interviews and real data, serving as a shared reference for marketing, sales and product decisions. Its value is in replacing "the customers" with a precise, shared description: when a team wonders whether an argument lands, they have a concrete person in mind rather than an abstract average. Its limitation lies in how it is often produced: an illustrated document, written in a workshop without speaking to a single customer, and filed away after the meeting.
What a useful persona contains
| Section | What it brings | The full destination URL |
|---|---|---|
| Professional situation | The context of the decision | Marketing manager at an 80-person manufacturing SME, the only person in the role |
| The problem to solve | The real need, in their own words | "I can't tell my director what the advertising budget brings in" |
| Trigger | The event that starts the search | A board meeting where the marketing results were challenged |
| Decision criteria | What separates the solutions | Usable without technical skills, under €200 a month, data held in Europe |
| Objections | What blocks the decision | "Yet another tool nobody will ever open" |
| Sources of information | Where they look, and where you need to be visible | Google, LinkedIn, ChatGPT, a peer's recommendation |
| Role in the decision | Who recommends, who decides, who pays | Recommender; the leadership signs |
The decorative elements (an invented first name, a photo, hobbies, an inspirational quote) have never changed a marketing decision. They make the document feel serious without adding anything, and divert time from what matters: the objections and the decision criteria.
The method in five steps
- Start from your existing customers: list the last twenty deals won and five lost, with their sector, their size, the person you dealt with and their reason for deciding.
- Run ten to fifteen interviews: twenty minutes on the phone with recent customers, asking three questions: what problem were you trying to solve, how did you find us, what almost made you give up. Those interviews produce 80% of the material.
- Cross-reference with your data: the CRM for profiles, GA4 for journeys, Search Console for the questions asked, customer service for recurring objections.
- Group: two to four personas at most, matching different buying behaviours, not age brackets. How they relate to operational segments is covered in audience segmentation.
- Make the document actionable: one page per persona, with customers' exact words, the objections and the channels; then connect each persona to messages, content and pages.
What personas are actually for
- Writing your pages: the headline of a landing page repeats the customer's phrasing of the problem, not the company's internal vocabulary.
- Choosing channels: the sources of information mentioned in interviews point to the platforms to work on, as shown in which platforms suit your business.
- Building the content plan: every objection and every decision criterion becomes an article or a section.
- Targeting your advertising: the profile criteria feed your LinkedIn targeting and your lookalike audiences.
- Qualifying leads: the profile criteria of your main persona become those of your Lead scoring.
Why most personas are useless
Three causes recur. The persona is built in an internal workshop from assumptions, which reproduces the team's beliefs instead of correcting them. It describes an identity (age, family situation, hobbies) instead of a buying behaviour — yet two people with identical profiles can buy for opposite reasons. And it is connected to no decision: no content, no page, no targeting changes after it is written. A useful persona fits on one page, quotes customers' real sentences, and turns up in the headings on your site.

Frequently asked questions
What is a persona in marketing?
The archetypal portrait of a customer segment, built from interviews and real data, serving as a shared reference for marketing, sales and product decisions. It describes a buying behaviour, not an identity.
What should a persona contain?
The professional context, the problem to solve in the customer's own words, the trigger for the search, the decision criteria, the objections, the sources of information consulted, and the role in the decision. An invented first name, a photo and hobbies are decoration.
How many personas should you create?
Two to four at most, matching distinct buying behaviours. Beyond that, no team remembers them and the messaging dilutes. They are built on ten to fifteen customer interviews and reviewed once a year.
How do you build a persona with no research budget?
By calling ten to fifteen recent customers for twenty minutes, with three questions: what problem were you trying to solve, how did you find us, what almost made you give up. Those interviews, cross-referenced with your CRM and your Search Console queries, are more than enough.
