What is Persona?
A research-grounded portrait of an individual buyer inside your ICP.
A persona is a semi-fictional profile representing a segment of your real customers, built from actual data and interviews rather than guesswork. It typically covers goals, frustrations, and buying behaviour so a team can write and design with a specific person in mind rather than an abstract audience.
Why Persona matters
Writing for everyone tends to produce copy that resonates with no one, because it has to stay vague enough to apply broadly. A well-built persona forces specificity: instead of writing for small business owners in general, you write for someone with a particular problem, budget, and level of knowledge, which almost always produces sharper, more persuasive messaging than a generic approach.
Personas also help teams make faster decisions without constant debate, since everyone can ask what a specific named persona would think of a new headline, feature, or price point. This is especially useful when a business serves several distinct buyer types who care about different things, since a single generic customer profile would blur those differences and produce compromises that satisfy nobody particularly well.
How Persona works in practice
- 01Build personas from real customer interviews and sales call notes, not assumptions about who you think buys from you.
- 02Include specific goals, objections, and the language customers actually use to describe their problem, not internal jargon.
- 03Limit yourself to two or three personas maximum, since more than that becomes impractical to design and write for.
- 04Share personas with everyone producing content, from ads to sales scripts, so they inform daily decisions rather than sitting in a document.
- 05Revisit personas annually or after major product changes, since buyer needs and language shift over time.
Common mistakes
- ·Basing personas entirely on demographic guesses, such as age and job title, with no real customer research behind them.
- ·Creating too many personas, which fragments messaging and makes every campaign decision more complicated than it needs to be.
- ·Writing a detailed persona document once and then never referring to it when producing actual content.
- ·Ignoring how personas evolve as the product and market change, leaving the profiles stale within a year or two.
How to measure Persona
Personas themselves are not measured directly, but their usefulness shows up in downstream metrics: whether messaging built around them improves conversion rate, engagement, or sales conversation quality compared with more generic copy. Checking with sales and customer support periodically on whether the persona still matches who they are actually talking to is a practical way to confirm it remains accurate.
What good looks like
A good persona is grounded in real interviews and data, specific enough to guide actual writing decisions, and genuinely used by the team producing content rather than filed away. It gets revisited and updated as the business learns more about its customers. MarketJargon builds persona-informed messaging into the agents it runs so copy stays targeted rather than generic.

Persona questions, answered
How is a persona different from a target market?
A target market is a broad description, such as small retail businesses in a certain region. A persona is a specific representative individual within that market, with named goals and frustrations, which makes writing and design decisions much more concrete.
How many customer interviews are needed to build a persona?
There is no fixed number, but five to ten in-depth interviews per segment usually reveals recurring patterns worth building a persona around. Fewer than that risks basing the persona on one unrepresentative person's views.
Can a B2B business have personas for multiple roles?
Yes, and it is often necessary, since a purchase decision may involve a user, a budget holder, and a technical evaluator who each care about different things. Separate personas for each role can sharpen messaging for every stage of the sale.
Do personas need a name and photo?
A name helps teams refer to them quickly in conversation, but the substance, goals, objections, and language, matters far more than cosmetic details like a stock photo, which can create a false sense of specificity.
