What is a UX score?
A UX score is a single number that summarizes how good a website's user experience is, derived from a consistent set of usability, design, and best-practice criteria so different pages can be compared on the same scale.
Why a single number is useful
UX quality is usually discussed in adjectives — "clean," "cluttered," "trustworthy." A score makes it measurable. That lets teams benchmark against competitors, track whether a redesign actually helped, and align stakeholders around an objective baseline instead of taste debates.
A score is a starting point, not a verdict. The value is in what sits underneath it: the specific, repeatable signals that produced the number and tell you what to change.
How the Sensei Score is calculated
The Sensei Score weighs three layers: functional UX (35%) — clarity, navigation, feedback, and whether the next action is obvious; aesthetic quality (35%) — hierarchy, typography, restraint, and visual confidence; and UX practices (30%) — design-psychology and conversion heuristics like cognitive load, signifiers, and social proof.
Each layer is evaluated against documented criteria, then combined into a weighted 0–100 score. Pages above roughly 70 are performing strongly on the observable signals; mid-range scores point to fixable friction; low scores usually signal unclear messaging, weak hierarchy, or heavy cognitive load. The full breakdown lives on the methodology page.
What a good UX score looks like
Across a benchmark of well-known, design-led websites, most land in a fairly tight band rather than scattering across the whole range — strong execution clusters, and truly exceptional pages are rare. That's why a score is most useful relative to peers in the same category, which is exactly what an industry ranking provides.
Frequently asked questions
- What is a good UX score?
- On Sensei's 0–100 scale, scores around 70 and above indicate strong UX on the observable signals. The most useful comparison is against other sites in your industry rather than an absolute cutoff.
- How is a UX score measured?
- Sensei extracts a page's structure and grades it across three weighted layers — functional UX (35%), aesthetic quality (35%), and UX best practices (30%) — then combines them into a single 0–100 score.
- Is a UX score the same as a Core Web Vitals score?
- No. Core Web Vitals measure loading and responsiveness performance. A UX score measures design and usability quality — clarity, hierarchy, and best-practice execution. They're complementary.
