How to use the hashtag generator

  • Enter a topic, niche, or keyword for your post.
  • Hit Generate to get a mix of broad and specific hashtags.
  • Tap individual tags to copy, or use Copy all.

Hashtag strategy that actually works

  • Mix sizes: combine a few big hashtags with several niche ones — niche tags are easier to rank in.
  • Stay relevant: only use tags that match your content, or reach won't convert.
  • Instagram: 8–15 well-chosen tags usually beat the full 30.
  • TikTok: 3–5 focused tags plus one trending tag works best.

Benefits

  • Suggests relevant hashtags for Instagram, TikTok and other platforms.
  • Saves time versus researching tags one by one.
  • Free and unlimited.
  • A quick way to widen the reach of a post.

Limitations to know

  • It suggests relevant tags but cannot predict which will perform for your specific audience.
  • Popularity shifts constantly, so a good tag today may be crowded next month.
  • It does not check a platform’s current rules on banned or limited tags.

Common mistakes to avoid

  • Stuffing every post with the maximum number of tags — a focused set usually does better.
  • Reusing the exact same block of tags on every post, which platforms can flag.
  • Chasing only huge tags where your post is instantly buried instead of mixing in niche ones.

Alternatives
