What earns each verdict

Same outcomes on every UXFix rule · how verdicts work
✓ Pass21

Checkout CTA has largest visual weight OR distinct primary styling.

~ Partial14

Checkout is prominent but competes with express-wallet buttons.

✕ Fail4

Checkout CTA visually indistinguishable from secondary actions.

not assessable is recorded when the rule applied but the store could not be judged on it (bot protection, a region lock, a step we could not reach), and not applicable when the store has nothing for the rule to judge. Those stores are left out of every number on this page, never guessed. Why we do that
Why it matters

The primary checkout button doesn't visually dominate the cart page. It competes for attention with promo-apply, save-for-later, or continue-shopping controls.

Cart is a decision moment. If the buyer's eye doesn't land on "Checkout" instantly, they scroll around, get distracted by promo hunting, and leave. Making the checkout CTA the biggest, brightest thing on the page measurably lifts completion.

That sentence is the one a failing store sees in its own UXFix report.How rules are weighted and scored

The fix

The same steps a failing store sees in its report

A pass means: Checkout CTA has largest visual weight OR distinct primary styling.

Severity
High
Score gain
+1.3pts
Page

Score gain is roughly what a fail-to-pass change adds; rules that could not be judged are left out, which can move it a little. Re-run a free audit after the change ships to confirm the verdict moved.

Checklist for the pass

What our auditors say about this rule

The cart page has exactly one job. If the checkout button is competing with four other buttons, it is not doing it.
