Do Hashtags Still Work in 2025?

Yes — but their role has evolved. On Instagram, hashtags are now more of a content categorization tool than a primary discovery driver (Instagram's own data suggests Reels and Explore are the primary discovery channels). On TikTok, hashtags remain significant for the algorithm to understand content categories. On Twitter/X, hashtags affect search visibility directly.

Hashtag Strategy by Platform

Instagram

Instagram currently recommends 3–5 highly relevant hashtags per post (down from the old advice of 30). Focus on specificity over volume:

  • 1-2 niche-specific hashtags (5K–200K posts): #MinimalistFoodPhotography
  • 1-2 mid-range hashtags (200K–1M posts): #FoodPhotography
  • 1 broad hashtag (1M+ posts): #Food

TikTok

Use 3–5 hashtags per video. Mix one trending hashtag with 2–3 niche-specific ones. TikTok hashtags affect which For You Pages your video appears on — relevance is more important than volume.

Twitter/X

Use 1–2 hashtags maximum. Twitter's character limit makes hashtag stuffing impractical, and research shows posts with 1–2 hashtags consistently outperform those with 5+.

Hashtag Research Best Practices

  • Check competitors: Look at the hashtags used by top posts in your niche
  • Avoid banned hashtags: Some hashtags are shadowbanned on Instagram. Search a hashtag before using it — if the "Recent" tab shows only old posts, it may be restricted
  • Rotate your hashtags: Using the exact same hashtag set repeatedly can limit reach. Vary them based on content
  • Check character count: Each hashtag counts toward your caption's character limit. Use our Character Counter to verify
