Although some critics have claimed hashtags don’t have the same impact as titles or descriptions, YouTube has confirmed they still contribute to:

- Suggested video placement – videos with relevant hashtags are grouped with similar content.
- Audience segmentation – connecting content to micro-communities.
In short, hashtags are a bridge between searchable metadata and audience intent.

- Content categories – like gaming, beauty, tech.
- Viewer watch history – ensuring relevant recommendations.
