Start Free TestWhat it means
Blocking keywords means any video with a word you pick, like prank or scary, is kept off your child's screen.
Why parents do it
Parents do it to stop whole kinds of videos at once, even from channels they already trust.
What you need
- The YouTube app on your child's device
- Your child signed in to YouTube
- Time to mark each video
How to set it up in YouTube
YouTube's closest tools sit on each video: tap More, then Not interested or Don't recommend channel. You do it one video at a time.
- On a video, tap More ⋮
- Not interested
- Don't recommend channel
- Repeat for every video
Where YouTube falls short
Here's the catch. YouTube has no keyword filter for parents, and Not interested only changes recommendations. A prank video can still play from search.
| Feature | YouTube | WhitelistVideo |
|---|---|---|
| Block a word | No such setting | Add any word |
| How it works | One video at a time | Checks titles and descriptions |
| Search results | Can still play | Blocked if the word matches |
The better way: WhitelistVideo
In WhitelistVideo, open Blocked Keywords and add words like prank or scary. Videos whose titles or descriptions contain the word are blocked.
It works even on channels you approved. If one video's title or description contains a blocked word, your child sees a block screen instead.
