Failure reference
Images without a text alternative.
A screen reader meets a filename where a sighted visitor sees your bestselling product. The most common automated finding on European commerce sites — and one template attribute away from fixed.
What fails — and who it fails
The failure, in plain language.
Product photos, category banners, payment icons, trust badges — when an <img> has no alt attribute, assistive technology has nothing to announce but a filename. For a blind shopper the product grid becomes a list of file paths; for a voice-control user, an unlabeled image is untargetable.
Detection — what the machine can and cannot judge
How the scanner finds it.
- Every <img>, role="img" and image input is checked for an accessible name in the rendered DOM.
- Missing alt, empty names on informative images, and aria-hidden misuse are flagged with the exact selector and markup.
- What automation cannot judge: whether the text is good. alt="image" passes a machine and fails a human — alt quality stays open in the coverage matrix until a human signs it off.
The legal reading — factual, not fearful
Where this sits in enforcement.
1.1.1 is a Level A criterion — the baseline layer every European regime inherits through EN 301 549. It is concrete, screenshot-able and trivially demonstrated, which is why missing alternatives appear early in German Abmahnung letters and regulator correspondence. The same properties make it the fastest finding to clear from your file.
The fix — by pattern
4 patterns cover nearly every instance.
- <img src="/img/p/8841.webp">
+ <img src="/img/p/8841.webp" alt="Leather weekender bag, cognac">+ <img src="/img/divider.svg" alt="">+ <svg role="img" aria-labelledby="t1"><title id="t1">Free shipping</title>…</svg>- <input type="image" src="/img/search.png">
+ <input type="image" src="/img/search.png" alt="Search">Fix the template, not the page — one change typically clears every instance at once. The triage engine groups findings by template pattern for exactly that reason.
Verification — resolution is evidence, not a checkbox
Fixed means a scan said so.
On monitored domains, mark the finding fixed and the next scan verifies it: zero remaining instances converts the finding to Resolved, and both the claim and the confirmation land in the append-only ledger. Criteria that need human judgement close through sign-off in the coverage matrix — covered by the right method, never by assumption.
