TikTok Hashtag Tips
Stick to 3-5 hashtags
Even though TikTok has no strict hashtag cap, 3-5 well-chosen tags perform best. Overloading hashtags takes up caption space and does not improve distribution through the For You page.
Use trending hashtags strategically
Check TikTok's Discover page for trending hashtags and sounds. Pairing a trending tag with a niche-specific one helps the algorithm place your video in front of the right audience.
Skip generic tags like #fyp
Tags like #fyp, #foryou, and #viral are used on billions of videos and provide zero signal to the algorithm. Replace them with specific topic tags that describe what your video is actually about.
Hashtags count toward your caption limit
TikTok captions allow up to 4,000 characters. Every hashtag you add eats into that space, so keep tags concise and leave room for a compelling caption that encourages comments.
Research tags inside the app
Type a keyword in TikTok search and check the Hashtags tab to see view counts. Choose tags with 1M-100M views for the best balance between discoverability and competition.
