The short answer
Place an example where the reader must apply a distinction or make a decision. Label invented scenarios clearly and do not turn them into testimonials or campaign evidence. The purpose is to demonstrate reasoning, not to borrow credibility from a fictional success story.
A worked example
A fictional buyer compares an $80 placement-only quote with a $140 writing-inclusive quote. The example can show which fields remain unknown without claiming either offer exists. It teaches the comparison process. A sentence saying the buyer achieved a 300% increase would add an unsupported result unrelated to the worksheet's function.
A practical checklist
- Choose a scenario that exposes the decision the reader is likely to face. Include only the details needed to make the reasoning concrete.
- State which assumptions are illustrative and which facts come from a source. Keep example numbers separate from current prices or measured outcomes.
- Walk through the decision and its remaining unknowns. End by explaining what additional evidence would change the choice.
What to avoid
Avoid using stock avatars, brand logos or fictional names to imply an actual client endorsement. An honest worked example can be professional and persuasive without pretending it happened. Preserve the scenario label if the example is reused in a short answer or a social card.
A useful follow-up
Can I use invented numbers in a worked example?
Yes, when they are clearly illustrative and are not presented as real prices, forecasts, evidence or customer results.
