Does AutoPlay mean?
The Autoplay feature on YouTube makes it easier to decide what to watch next. When Autoplay is on, another related video will automatically play after a video ends.
Where are YouTube preferences?
General settings
If you select your profile picture in the top-right corner of any YouTube page and select Settings, you'll get to the account settings page. From here, you can change general settings, like your password and email preferences—basically how often YouTube sends you email updates.
Does AutoPlay on YouTube count as a view?
Autoplay plays back an “Impression” of the video , but does not actually activate YouTube, so the autoplay "Impression" is not counted a view by YouTube. If the viewer actually clicks on the video, YouTube counts it as a view.
