Look for the destination
Imagine two fictional pages explaining a health measurement. One helps readers interpret its limits. The other explains the same measurement and directs readers to buy a device. The second page is not automatically inaccurate, but its commercial purpose is relevant context.
A useful question is whether the explanation remains helpful to someone who decides not to buy. Does it describe alternatives, uncertainty, and situations where the product may not answer the question?
Different success measures
| Goal | Possible measure | What the measure does not establish |
|---|---|---|
| Explain a concept | Readers can describe it accurately | They changed a health outcome |
| Help use a service | People can complete the booking process | The service is suitable for everyone |
| Promote a product | Purchases increase | The claims were balanced or the product improved health |
The table is a conceptual comparison, not an evaluation of a particular campaign. BLS describes health education specialists as developing and evaluating programs and materials. The work can involve more than delivering a persuasive message.
A sales goal does not settle the evidence question
Commercial incentives can influence what is emphasized, but they do not logically determine whether a claim is true. Conversely, a nonprofit source can still publish an inaccurate or incomplete explanation.
NCCIH's guidance directs readers to check whether sources support health claims. That remains useful regardless of who published the page.
A practical editorial test
Read the page once while ignoring its purchase or sign-up button. What does it teach? Then read only the call to action. Does the evidence supplied justify that step, or does it merely explain a related scientific idea? Keeping those two readings separate helps identify where education ends and persuasion begins.
