Recommended hashtag counts by platform
| Platform | Practical Hashtag Target | Where to Place Them |
|---|---|---|
| YouTube Videos & Shorts | 3 hashtags (max 60 allowed by policy) | At the very bottom of the video description |
| Instagram Posts & Reels | 3 to 5 focused hashtags | At the end of the caption |
| TikTok Videos | 3 to 5 topic hashtags | After a clear, keyword-rich one-sentence caption |
| LinkedIn Posts | 2 to 3 industry hashtags | Below the final paragraph of your post |
Best practices for choosing hashtags
- Keep hashtags specific to the post. Only copy tags from the generated list that match what your video or post actually covers.
- Mix root terms with intent modifiers. Pairing a topic word with suffixes like tips, tutorial, or strategy helps categorize instructional content.
- Use CamelCase for accessibility. Capitalizing each word (such as #SourdoughStarter) helps screen readers pronounce multi-word hashtags clearly.
