Google today announced that is using browsing behaviour to identify the websites with the highest percentage of visitors that play media with sound. Users can see the list of websites typing this on Chrome: chrome://media-engagement
The policy is enabled in the latest version of Chrome—update today. On the media engagement list, users can see the visits, playbacks and the score. According to Google, the consumption of the media (audio/video) must be greater than 7 seconds. Audio must be present and unmuted. Tab with video is active. The Size of the video (in px) must be greater than 200×140.
Users without browsing history will also be integrated on this. Chrome allows autoplay for over 1,000 sites where Google sees the highest percentage of visitors playing media with sound.
“As users teach Chrome, you may find that you need to click “play” every now and then, but overall the new policy blocks about half of unwanted autoplays, so users will have fewer surprises and less unwanted noise when you first arrive at a website,” said John Pallett, Product Manager and Media Muter on Google Chrome at Google.
For publishers autoplay is important to show more ads on preroll and in stream format. According to the Coalition for Better Ads, autoplay video ads are allowed as long as the sound is muted.
