Tagging someone in a YouTube comment is a one-step action — there’s no request or approval process involved, just an @ mention.
Step-by-Step
- Open the video where you want to leave a comment.
- In the comment box, type @ followed by the channel’s handle.
- Select the matching channel from the dropdown that appears as you type.
- Finish writing your comment and post it — the mention becomes a clickable link to that channel immediately.
Why Tag Someone?
- To direct a reply specifically at one person in a busy comment thread.
- To credit a collaborator, guest, or another creator you’re referencing.
- To make sure a specific channel notices your comment, since a mention can surface in their activity depending on their notification settings.
Good Etiquette When Tagging
- Only tag people who are relevant to the conversation — tagging several unrelated channels in one comment reads as spam.
- Don’t tag a business or creator to ask about something unrelated to their content; check their About section first if you’re unsure what they cover.
