Comment on videos
Comments give you an easy way to engage with other people on YouTube. You can view and contribute to the conversation in the comments section of videos and on the Discussion tab of channels (if the channel owner has enabled the Discussion tab).
View & organize comments
View comments on videos
To view comments on a video, just scroll down the video's page. Replies are threaded to make it easy to follow conversations. All comments on YouTube are public and anyone can reply to a comment that you post.
Change what comments show first
On the web, you can change how comments show under a video. Just use the drop-down menu to choose Top comments or Newest comments:
Top comments first: Show comments in a ranked view that highlights comments such as those from the video creator, comments generating discussion from the viewers, and comments that have been voted up by the community.
Newest comments first: Show the most recent comments at the top.
Note: YouTube apps for Android and iOS don't yet support all comment features. For example, sorting by most recent comments is not available in the Android app.
We're working on updating the apps, but in the meantime, you can sign in to the YouTube mobile website from your device's browser to like or dislike comments.
Post & interact with comments
If a video's owner has enabled comments, you can post comments and like, dislike, or reply to other people's comments on a video. You can also edit or delete any of your own comments. Replies to a comment are threaded beneath the original comment so you can follow the conversation. Read more - https://support.google.com/youtube/answer/6000964?hl=en&ref_topic=3014329
