What earns each verdict

Same outcomes on every UXFix rule · how verdicts work
✓ Pass9

Discount line item visible with amount.

~ Partial0

Discount amount shown but not labeled clearly.

✕ Fail16

Discount silently reduces total.

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

A discount has been applied but there is no explicit line showing the discount amount and label. The saving happens silently.

Buyers who applied a code want to see it working. A silent adjustment feels like the code did not work, and they may re-apply, try a different code, or abandon in frustration.

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: Discount line item visible with amount.

Severity
Medium
Score gain
+0.9pts
Page
Cart

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
0 of 3

Tick each step as you ship it. The audit judges the live store, so re-run it once all of them are done.

What our auditors say about this rule

A discount that changes the total silently makes the shopper wonder what else changed silently.
