Start with
better questions.

A persona is a practical sketch of a type of customer. Its value comes from explaining a decision: what someone needs, what stands in the way, and what would make them act.

Start with the problem.

“Mo is a self-employed plumber whose clients pay late” is a useful start. Late payments explain why an automatic reminder might matter. A list of hobbies or demographic details would tell you far less about this decision.

Keep only what helps.

Include the goal, problem, motivation, buying considerations, and context. Avoid invented detail that has no bearing on the choice. In real work, validate your assumptions through research with customers.

People can like a product and still be the wrong audience for a particular campaign. Look at the whole situation, rather than a single matching detail.

Need and value

Identify the problem, then ask how directly the product solves it. A freelance invoicing tool can help a designer save time and a plumber chase late payments, but those are different reasons to try it.

Context and motivation

Consider where, when, and why someone encounters the offer. An urgent cash-flow problem makes a late-payment message more relevant than a general desire to organise paperwork.

Friction

Look at what could stop a good match from becoming a decision: price, effort, timing, trust, or a missing capability. A tool that only works on a desktop may be awkward for someone moving between jobs.

A feature describes what a product does. A benefit explains why that matters to a person. A useful message connects the two without making a promise the product cannot keep.

The audience changes the emphasis.

Maya, a designer, wants less time spent creating invoices. A message about preparing invoices quickly fits her need. Mo, a plumber, wants clients to pay on time. A message about reminders addresses his problem more directly.

Respect the limits of the example.

The product and people in these guides are fictional. In real campaigns, support your claims with evidence and test your assumptions with the people you want to reach.
