If a video's owner has turned on comments, you can post comments and like, dislike, or reply to other comments on a video
To view comments on a video, scroll on the video's page. Replies are threaded to make it easy to follow conversations. YouTube comments are public and anyone can reply to a comment that you post.
If you can't find a comment after you get a notification, it's possible that the comment has already been removed. Comments can be removed by the original poster, the channel owner, or for policy violations.
While reading comments, you may see certain keywords in blue text on mobile devices. You can click these keywords, called “search shortcuts,” to search for that term on YouTube. Learn more about search shortcuts.
