Platform-Specific Hashtag Strategies

Instagram Hashtag Strategy 2025

Optimal number: 3-5 highly relevant hashtags (Instagram confirmed in 2024 that less is more)

Instagram Hashtag Mix Formula:

1-2 niche hashtags (low competition, 10K-100K posts)
1-2 medium hashtags (moderate competition, 100K-500K posts)
1 branded hashtag (your own unique hashtag)

Placement: Place hashtags in the caption (not comments) for best performance

Update frequency: Rotate hashtags every 2-3 posts to avoid being flagged as spam

TikTok Hashtag Strategy 2025

TikTok Hashtag Priorities:

#FYP or #ForYouPage - Still relevant for discovery

Common Hashtag Mistakes to Avoid

❌ Using Too Many Hashtags

Instagram's algorithm may flag you as spam. Stick to 3-5 relevant tags.

❌ Only Using High-Competition Hashtags

Your content gets buried quickly. Mix difficulty levels for better visibility.

❌ Irrelevant Hashtags

Using #love on a B2B post hurts credibility and engagement quality.

❌ Never Changing Hashtags

Using the same set repeatedly can trigger spam filters. Rotate regularly.

❌ Not Researching Before Using

Some hashtags are banned or associated with negative content. Always check first.
