A homepage is an explanation under pressure
Most visitors arrive without the context your team has. They do not know your roadmap, product category debates, or why the latest feature matters. They make a fast decision: continue, or leave.
A clarity test measures what survives that first encounter. It is not a design preference survey. The question is whether the intended audience can identify the product, the customer, the outcome, and the next step.
Ask recall questions, not opinion questions
Show the page briefly, remove it, and ask: What does this company sell? Who is it for? What changes after using it? What would you click next?
Do not ask whether the page looks good. Visual taste is weak evidence. Accurate unaided recall is much closer to the job your homepage must perform.
Turn confusion into a rewrite brief
Group wrong answers by pattern. If people understand the category but not the outcome, the headline is probably too descriptive. If they understand the outcome but cannot identify themselves, the audience signal is missing. If they understand both but do not trust the claim, proof is the bottleneck.
The resulting brief should name the misunderstanding to remove—not a style to imitate.
