Missing new uploads from a favorite channel?
If you never want to miss a new video from a channel you love, setting its notification bell to "All" gets you an alert the instant it is uploaded, instead of hoping it shows up in your feed.
Each channel keeps its own notification setting
The bell setting is independent for every channel you are subscribed to, so you can set your absolute favorites to "All" while leaving everything else on "Personalized" -- a level of fine-tuning that a single all-or-nothing switch could not give you.
Frequently Asked Questions
Can I turn on the notification bell without subscribing first?
No, the notification bell only appears on channels you are already subscribed to. You need to subscribe first before the bell icon shows up at all.
What exactly does "Personalized" use to decide what to send?
It is based on YouTube's analysis of your viewing habits, picking out videos it thinks you are likely to be interested in. That usually means fewer alerts than "All," but the exact criteria are not made public.
