The 60-Character Mobile Truncation Rule
YouTube permits titles up to 100 characters in length. However, over 70% of YouTube watch time occurs on mobile smartphones, where video titles longer than 50-60 characters are abruptly truncated with an ellipsis (...).
If your main curiosity hook or primary keyword is placed at character 75, mobile users will never see it in their recommended feed. Always front-load your primary keyword within the first 45 characters.

Frequently Asked Questions
Can I use hashtags inside the video tags box?
No. The video tags box in YouTube Studio expects plain comma-separated phrases without '#' symbols. Hashtags belong in the video description.
What is the penalty for keyword stuffing tags?
Adding misleading or irrelevant celebrity/trending tags violates YouTube spam policies and can result in video suppression or strikes.
