Liking a video is a quick way to let a video creator know that you enjoy their work. If you're signed in, liking a video will add it to your "Liked videos" playlist, which is private.
If you’re not the biggest fan of a long-form video or livestream, disliking is one way to show your opinion. Keep in mind that if you want to report inappropriate content, you should report the video instead.
Like or dislike videos
To like a video, use thumbs up 
for Shorts. To dislike a long-form video or livestream, use thumbs down
Hearts on comments
If you leave a comment on the Posts tab or the watch page, creators can use a heart to show appreciation for your comment.
When a creator uses a heart on your comment, you'll know in two ways:
- On your comment, you'll see the creator's avatar with a small heart
.
- You'll get a notification (depending on your opt-in settings for computer and mobile) that a channel owner "loves your comment."
