Frequently asked questions
Why include a subjective 'first impression' rating alongside structural checks?
Structural clarity (headline, CTA, jargon) predicts comprehension but doesn't capture everything — a self-rated first impression adds a gut-check the structural checks alone can miss.
What's a good Clarity Score before launch?
Above 75 suggests a first-time user will likely understand the screen unaided. Below 50 usually means the core message needs a rewrite, not just a design tweak.
Does this replace real first-time user testing?
No — it's a fast self-assessment. A short unmoderated test with someone unfamiliar with the product remains the most reliable clarity check.

A five-second usability test gathers real first-time reactions but needs recruited participants. Clarity Score gives a fast structural estimate before or alongside that testing.
