Freeze one page and write the intended understanding
Save the exact desktop and mobile version, including traffic-source message, date, and any personalization state. Before observing anyone, write five correct answers: what is offered, whom it is for and not for, what credible evidence exists, what material cost or constraint applies, and what the primary action will do. This prevents the team from redefining success after hearing responses. Digital.gov frames plain language as content for a specific audience and includes testing for understanding; turn that principle into a record that compares intended meaning with what a new visitor actually constructs.

Recruit for unfamiliarity and decision context
Use people who resemble the intended reader but have not reviewed the page with the team. Capture relevant context such as prior category knowledge, device, language, accessibility needs, and whether they would realistically face the decision. A handful of sessions can locate comprehension mechanisms; it cannot estimate population conversion or prove universal clarity. Exclude colleagues who know the offer vocabulary. If only convenience participants are available, label the exercise exploratory and narrow the claim to the misunderstandings observed rather than awarding the page a pass percentage.

Separate rapid orientation from task comprehension
Begin with a brief natural exposure, then hide the page and ask what the participant thinks it offers, for whom, and what they would do next. Record exact language without correcting it. Restore the page and give realistic tasks: find the price path, identify a limitation, locate evidence for a named claim, and explain what clicking the primary action will cause. Rotate task order when order effects could teach later answers, and note every prompt the facilitator had to repeat. A rapid impression can reveal whether the page establishes orientation; the task phase shows whether material information is findable and interpretable. Do not call the exercise a five-second scientific test or treat recall of a slogan as offer comprehension.

Probe the mismatch without teaching
Ask neutral questions: 'What led you to that conclusion?', 'Where would you look next?', and 'What do you expect after selecting this?' Avoid praising correct answers or revealing the intended message mid-session. Nielsen Norman Group's match-to-real-world and visibility heuristics help classify problems, but use the participant's behavior as the evidence. Mark whether information was absent, overlooked, found but misunderstood, contradicted elsewhere, or expressed in unfamiliar terms. Also record false certainty, where a participant gives a confident answer the page does not support.

Prioritize by decision consequence
Group findings by the five intended answers and rank them using harm, recurrence in the sessions, and ease of verification. Misunderstanding a recurring fee or eligibility limit outranks failing to remember a tagline. Preserve a small table of evidence for and against each suspected cause before choosing the revision. Choose the smallest coherent revision: name the offer more concretely, move a qualification beside the claim, make a price route explicit, change an action label, or split an overloaded sentence. W3C guidance supports succinct, unambiguous content and separate instructions, but resist mechanically shortening text when the missing words carry a decision-changing condition.

Retest the changed inference and archive the record
Run the affected task with new participants or, when resources are limited, conduct a clearly labeled second exploratory round. Keep the same intended-answer rubric so improvement is not defined by team preference. Archive page version, participant context, prompts, verbatim misunderstandings, change rationale, unresolved gaps, and the trigger for another review. Include disconfirming responses rather than keeping only quotes that make the revision look successful, and note whether facilitation or device conditions changed between rounds. Stop when the high-consequence inference is consistently understood in the bounded study and no new material ambiguity appears. Continue monitoring support questions, refunds, and downstream fit because a controlled session cannot reveal every real-world context.
