Frequently Asked Questions

Instagram allows up to 30, but studies show 3–11 high-quality tags often perform best for engagement. TikTok and Twitter usually benefit from 3–5 very specific tags.


Does this tool use an API or require internet? +

No. The generator uses a built-in database of thousands of trending tags that runs entirely in your browser. It works offline and never tracks your searches.


Are the hashtags relevant to my keyword? +

Yes. The tool matches your keyword against a curated tag database and mixes broad high-reach tags with niche-specific ones to give you the best balance of visibility and targeting.


Can I use these hashtags on TikTok and Twitter too? +

Yes. The generated tags work across Instagram, TikTok, Twitter/X, and LinkedIn. Just pick the most relevant ones for each platform — fewer tags work better on TikTok and Twitter.
