## How to do it

1. **Pick the tag.** One hashtag per call, such as #booktok or a brand's campaign tag.
2. **Call social.search.** platform tiktok, the tag and a limit. Each video has its views, likes, replies and shares.
3. **Rank the videos.** Sort by views to see what carried the tag, and check the dates to see if it is still active.
4. **Go deeper.** social.comments reads a video's comments; social.profile reads the creator behind it.

## Ask it like this

- Search #booktok on TikTok and tell me which kinds of videos get the most views. (`social.search`)
- Find the top videos under our category hashtag, then read the comments on the most viewed one. (`social.search`, `social.comments`)

## Worth knowing

- **Popular, not only recent.** Results here ranged from 2024 to 2026. Filter on the date if you only want this month's videos.
- **Creators are people.** The videos come from individual creators. Mask their handles in anything you publish.
- **Read only.** Nothing is liked, followed or commented. RouterGrowth is independent of TikTok.
