What earns each verdict

Same outcomes on every UXFix rule · how verdicts work
✓ Pass19

Explanation available on CVV field.

~ Partial5

Small icon but no accessible tooltip.

✕ Fail5

CVV requested with no context.

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 CVV / security code field has no explanation or tooltip. Shoppers who don't know what CVV is are stuck.

CVV confusion is a top-10 reason for card-form abandonment. A single help icon fixes it for free.

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

Every published UXFix audit this rule could be judged on, as of 23 Sep 2026. A count of real stores, not a simulation of yours.

The fix

The same steps a failing store sees in its report

A pass means: Explanation available on CVV field.

Severity
Low
Score gain
+0.5pts
Page
Checkout

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.
