## Frequently asked questions

- **How long can a single hashtag be?**
  
  Most platforms allow up to 100 characters per tag, but tags over ~30 characters are rarely searched and dilute reach. Our tool flags anything over 24.
- **How many hashtags can I use on Instagram?**
  
  Up to 30 per post and 10 per Story. Reels follow the post rule (30). The current best-practice mix is 3-5 high-relevance tags.
- **TikTok hashtag rules?**
  
  No hard tag count, but the entire caption (including tags) caps at 2,200 characters. Aim for 3-5 tags mixing one trending tag with niche terms.
- **Does YouTube use hashtags?**
  
  Yes — first three hashtags in a description appear above the title. Maximum 60 per video; over 15 disables them entirely.
- **What characters are allowed in a hashtag?**
  
  Letters, numbers, and underscores. Spaces, punctuation, and emojis break a tag. Our tool warns you about invalid characters in real time.
- **Are there banned or shadow-banned tags?**
  
  Platforms keep undisclosed lists of restricted tags. We maintain a community-sourced list and flag tags suspected of being limited.
- **How is character count different from word count?**
  
  A tag is one "word" but its character count drives discoverability — short, focused tags rank better than long compound ones.
- **Can I paste a whole caption to scan all tags at once?**
  
  Yes. Paste any text and the tool extracts all "#tag" tokens, counting characters per tag and total tag-character usage.
