TikTok Hashtags Guide: Ranking in 2025

By Fast-Vid Editorial · Updated December 2, 2025

TikTok hashtags in 2025 are more powerful than ever — but not in the way most people think. While hashtags help categorize your content, TikTok now relies heavily on **search-based discovery**, meaning keyword-rich captions and spoken words matter more.

The Truth About Hashtags in 2025

Using 20 hashtags no longer works. TikTok rewards:

Relevance over quantity
Long-tail topical hashtags
Hashtags matching your niche
Hashtags people actually search

Best Hashtag Structure for Ranking

Use this formula:

2 Niche hashtags (#fitnessforwomen, #smallbusinesscheck)
2 Broad category hashtags (#fitness, #business)
1 Trending/audio hashtag

How TikTok Uses Hashtags for SEO

TikTok scans your:

Caption keywords
Hashtags
On-screen text
Spoken words

Use Searchable Hashtags

Examples:

#howtodownloadtiktok
#tiktokseo2025
#contentcreator101

Red Flags to Avoid

Too many hashtags (looks spammy)
Using irrelevant trending tags
Copying hashtags from viral videos that aren’t your niche
