Aria Live Checker
Paste your page HTML and find invalid aria-live tokens, silenced alerts and empty live regions.
What this tool gives you
Check live regions
Paste your page HTML. Analysis runs locally in your browser — nothing is sent anywhere.
Status, alerts and toasts need aria-live="polite" or assertive — never a made-up token.
What this checker looks for
WCAG 4.1.3 fails when a status change is visible but never spoken. Unknown aria-live tokens are treated as off.
Valid tokens
aria-live must be polite, assertive or off — true/false do nothing.
Alerts stay on
role=alert plus aria-live=off silences the emergency message.
Implicit roles
status, alert, log, timer, marquee and <output> count as live regions.
Empty regions
Fine if JS fills them later; otherwise AT has nothing to announce.
Toasts and saves
Form success copy needs a live region, not a silent banner.
0–100 score
Track live-region hygiene across templates, not just the homepage.
How to wire a live region
Three rules cover almost every silent toast in the wild.
Pick polite or assertive
polite for saves and progress. assertive for blocking errors. Never true/false.
Do not silence alerts
role=alert is already live. aria-live=off on an alert mutes the emergency.
Keep text to speak
Start with copy, or fill the region with JS. An empty container never announces.
Why answer engines care about live regions
Spoken status copy is a cheap-to-parse signal that the page has real conversion feedback, not a silent trap.
| Signal | What engines infer | Why it helps |
|---|---|---|
| Valid aria-live | Status changes are announced. | Extractors can quote Saved vs Failed, not silent banners. |
| Unsilenced alerts | Errors reach AT users. | Lower bounce on AI-referred checkout visits. |
| role=status / alert | The page uses platform live roles. | Predictable structure beats a custom toast div. |
| WCAG 4.1.3 pass | Status messages are programmatically determined. | Citable, trustworthy pages get quoted more often. |
| Filled regions | There is copy to speak. | Empty containers look like unfinished UI. |

Aria live FAQs
What values does aria-live accept?
Only polite, assertive and off. Tokens like true, false or yes are ignored, so the region never speaks. Use polite for saves and assertive for blocking errors.
Why is role=alert plus aria-live=off a fail?
role=alert implies assertive. Setting aria-live=off overrides that and silences the emergency message. Leave the implicit live value or set assertive.
Are empty live regions always wrong?
No. Many toasts start empty and get filled by JavaScript. The checker warns so you can confirm a fill path exists — a permanently empty region never announces.
