TikTok Hashtag Strategy: Find and Use Trending Hashtags in 2025

How TikTok Hashtags Work

TikTok's hashtag system is both simpler and more nuanced than other platforms. Understanding how the algorithm processes hashtags is essential for maximizing your content's reach.

The Algorithm and Hashtags

TikTok uses hashtags to:

• Categorize content by topic
• Match videos to interested users
• Power the Discover page
• Enable search functionality
• Track trending topics

Hashtag Behavior on TikTok

Unlike Instagram, TikTok hashtags:

• Have less strict "size" hierarchies
• Can trend and fall quickly
• Are heavily influenced by challenges
• Often include sound associations

Finding Trending Hashtags

Method 1: TikTok Discover Page

The Discover page shows:

• Currently trending hashtags
• Trending sounds (often with associated hashtags)
• Popular challenges
• Rising topics

Check daily for fresh opportunities.

Method 2: Search Function

Use TikTok's search to:

• Type your topic and see suggestions
• Check hashtag view counts
• Browse top videos in each hashtag
• Discover related hashtags

Method 3: Competitor Analysis

Study successful creators:

• What hashtags do they use consistently?
• Which posts performed best?
• What niche-specific tags appear?
• How many hashtags do they use?

Method 4: TikTok Creative Center

TikTok's official tool shows:

• Trending hashtags by region
• Performance metrics
• Growth trajectories
• Related content

Method 5: Third-Party Tools

Use analytics platforms:

• Trend tracking services
• Hashtag research tools
• ToolPop's Hashtag Generator
• Analytics dashboards

Hashtag Categories for TikTok

These build community and attract targeted viewers.

Building Your Hashtag Strategy

The Optimal Number

TikTok allows up to 100 characters of hashtags in captions. Most successful creators use:

• 3-5 hashtags: Clean, focused approach
• Maximum: Usually under 10

Quality over quantity applies strongly on TikTok.

The Strategic Mix

For each post, include:

1 Trending hashtag (if relevant)
1-2 Niche hashtags
1 Content type hashtag
1-2 Community hashtags

Example for a cooking video:

• #recipetok (niche)
• #easyrecipes (content)
• #quickmeals (community)
• #[trendingfoodchallenge] (trending)

Adapting to Your Niche

Different niches have different hashtag cultures:

Beauty/Fashion: #grwm #ootd #makeuptutorial #beautytok

Fitness: #gymtok #workout #fitnesstips #gains

Business: #smallbusiness #entrepreneur #businesstips #sidehustle

Comedy: #comedy #funny #relatable #humor

Education: #learnontiktok #edutok #facts #didyouknow

Trending Hashtag Analysis

Identifying True Trends

Not all "trending" hashtags are equal:

Good trend indicators:

• Rapid view count growth
• Multiple creators participating
• Associated with trending sound
• Featured on Discover page

Red flags:

• Static view counts
• Old content dominating
• No recent engagement
• Irrelevant to your niche

Trend Timing

Understanding trend lifecycle:

• Emerging (0-48 hours): Early adoption advantage
• Peak (2-7 days): Maximum visibility, high competition
• Plateau (1-2 weeks): Still relevant, less urgency
• Declining: Diminishing returns, move on

When to Jump on Trends

Act quickly when:

• Trend aligns with your niche
• You can add genuine value
• You have time to create quality content
• The trend isn't offensive or problematic

The FYP Hashtag Debate

Do #FYP Hashtags Work?

The debate continues:

Arguments for:

• Massive exposure potential
• Signal to algorithm
• Widely used by successful creators

Arguments against:

• Extremely competitive
• No targeting value
• May be ignored by algorithm
• Takes up character space

Best Practice

If using general hashtags:

• Don't rely on them alone
• Combine with niche hashtags
• Test with and without
• Track your own data

Challenge Hashtags

Participating in Challenges

Challenges are TikTok's engine:

• Often tied to sounds
• Have specific hashtags
• Create community moments
• Can go massively viral

Finding the Right Challenges

Look for:

• Challenges matching your brand
• Rising (not oversaturated) challenges
• Adaptable to your niche
• Appropriate for your audience

Creating Challenge Content

When joining a challenge:

• Put your unique spin on it
• Use the official sound
• Include the challenge hashtag
• Post while it's still trending

Hashtag Placement

Where to Put Hashtags

On TikTok, hashtags go in the caption:

[Your main caption text]

#hashtag1 #hashtag2 #hashtag3

Some creators:

• Blend hashtags into caption text
• Place at the very end
• Use line breaks for separation

Visual Considerations

Remember:

• Hashtags appear on video
• Keep caption concise
• Don't overwhelm visually
• Consider thumbnail appearance

Hashtag Mistakes to Avoid

1. Irrelevant Trending Hashtags

Using popular hashtags that don't match content:

• Confuses the algorithm
• Attracts wrong audience
• Leads to quick exits
• May be flagged as spam

2. Banned or Shadowbanned Hashtags

Some hashtags are restricted:

• Research before using
• Avoid controversial tags
• Check if content appears in hashtag feed

3. Only Using Massive Hashtags

Missing niche opportunities:

• #fyp has billions of videos
• Niche hashtags = better targeting
• Build community presence

4. Same Hashtags Every Post

Lacks strategic thinking:

• Match hashtags to specific content
• Rotate based on topic
• Include post-specific tags

5. Too Many Hashtags

Looks spammy:

• Quality over quantity
• Focus on relevance
• Leave caption space for actual message

Advanced Strategies

Hashtag Testing Method

Systematically test effectiveness:

Week 1: Posts with trending + niche hashtags Week 2: Posts with only niche hashtags Week 3: Posts with broad + niche hashtags Week 4: Posts with minimal hashtags

Compare performance across variables.

• Use the trending sound
