Autoplaying Media Without Mute

What This Means

The page contains a <video> or <audio> element with the autoplay attribute but without the muted attribute. The media will attempt to play audio automatically when the page loads.

Why It Matters for SEO

Autoplaying unmuted audio is one of the most disruptive experiences a webpage can create — it startles users, is impossible to stop without finding the player, and is inaccessible to users with cognitive disabilities who cannot quickly locate and disable the audio.

Chrome and most modern browsers block autoplay with audio by default, so the autoplay may not actually fire for most users — but the code intent is still problematic. Google's page experience signals include elements of user experience quality.

What the Platform Checks

The platform checks for <video> and <audio> elements with the autoplay attribute but without the muted attribute. Fires on detection.

How to Fix It

• If autoplay must be used (e.g., background video): add the muted attribute. Muted autoplay is allowed by browsers: <video autoplay muted loop playsinline>.
• For videos that should play with sound: remove autoplay. Show a play button — let users choose when to start audio.
• For accessibility: always provide controls (controls attribute) so users can pause, stop, and adjust volume.
• Consider WCAG 1.4.2 (Audio Control): any audio that plays for more than 3 seconds must be pauseable or stoppable by the user.
