# Announce dynamic content with ARIA live regions
Without live regions, screen reader users miss dynamic updates entirely—they won't know their form submitted, their cart updated, or an error occurred.
## Quick Reference
- Use aria-live='polite' for non-urgent updates (cart count, status messages)
- Use aria-live='assertive' only for critical alerts (errors, session expiry)
- Use role='alert' or role='status' for semantic live regions
- The live region must exist in DOM before content changes
## Check
Verify that dynamic content changes (notifications, form errors, loading states) use aria-live regions appropriately.
