## Frequently Asked Questions

### How many hashtags should I use?

Instagram: 5-15 relevant ones (max 30). TikTok: 3-5 trending ones. X: 1-2 max. LinkedIn: 3-5 professional ones. YouTube: 3-5 SEO-focused. More isn't always better.

### Do duplicate hashtags hurt engagement?

Duplicates waste your limited hashtag slots without adding value. Instagram counts each hashtag instance, so duplicates eat into your 30-hashtag limit.

### What makes a good hashtag strategy?

Mix sizes: 30% large (500K+ posts), 40% medium (50K-500K), 30% small/niche (<50K). Small hashtags give you a better chance of ranking in Top Posts.
