Use fewer, better tags
Hashtags should describe the actual video. A focused set usually looks more trustworthy than a long list of unrelated trending terms.

YouTube Hashtag Generator
Turn a video topic, keywords and niche notes into a clean hashtag set. Keep hashtags relevant and avoid stuffing unrelated tags.
Where to place them
Add a short hashtag line near the end of your description or use a few tags in a pinned comment when it genuinely helps viewers.
Avoid spam
Do not add misleading celebrity, news or brand hashtags if the video is not about them. Misleading metadata can hurt trust.
