- Monitor performance: Track which hashtag categories drive the most engagement and adjust accordingly

Understanding Hashtag Categories
- Primary Hashtags (High Relevance): These are the most directly relevant to your content. They describe your main topic, subject, or action and have the highest chance of reaching your target audience.
- Niche Hashtags (Community-Specific): These target specific interest groups, micro-communities, or specialized topics. While they may have lower overall volume, they often deliver higher engagement rates because the audience is more focused and interested.
- Trending Hashtags (Viral Potential): These leverage current events, popular challenges, seasonal themes, or viral trends. They offer the highest potential reach but may be less targeted to your specific content.
