Match the tool to the answer prospects need
Start with the answer prospects need, then choose the interaction that can produce it. A calculator invites prospects to enter numbers or information about their business to generate an answer, often numerical. An assessor uses targeted questions, usually through a survey or quiz, to produce a personalised report. A configurator lets prospects personalise a product or service according to their needs.
The distinction is the useful output: a calculation, a report or tailored options. Each format should give prospects personalised answers to the challenges they face, whether or not they become customers. Content Marketing Institute's 2025 guidance on buyer journeys places diagnostic assessments in discovery, while concept-specific assessments, solution finders and calculators can help buyers justify a decision.
Use the information prospects provide and how they interact with the questions to improve the tool over time, keeping the personalised answer useful to the person completing it.
