What belongs in one
- The segment it represents, named and sized. Without a segment behind it, a persona is a character sketch.
- Behavioural grounding: what this segment actually does, measured, not imagined.
- Motivation relative to the category: why they would or would not engage.
- Where and how they are reachable: geography and media behaviour, which turn a persona into a plan.
- What would put them off: often more useful than what attracts them, and often missing.
Grounding a persona in data
Segment first, persona second. Establish segments from observed behaviour (demographics, geography, affinities, media), confirm each is large and distinct enough to matter, then write a persona as a readable summary of what the data already showed. In that order, the persona adds memorability without adding invention.
A simple test: could someone check whether this persona is accurate? If no statement in it can be checked, it is a story about the audience, not a description of it.
Common mistakes
- Invented, not derived. A persona from a workshop encodes the team’s assumptions and lends them the authority of research.
- Detail without a decision. A favourite coffee order and a stock photo make a persona feel real without making it useful.
- Frozen. Personas written once and used for years describe an audience that has moved on.
- Unsized. Five personas shown as equals, where one stands for 60% of the audience and another for 4%, distort every priority that follows.
How Rascasse uses it
Rascasse provides the measured layer under a persona: the size, demographics, regions, interests, brands and media of each segment, per country, updated quarterly. Teams build segments with it and write personas on top.
