Frequently asked questions
How many hashtags should I use on Instagram?
Instagram allows up to 30 hashtags per post, but 3–10 highly relevant ones usually perform better than 30 generic ones. Mix a few specific niche tags with one or two broader ones.
How does this hashtag generator work?
It matches the words in your topic against hand-curated hashtag sets for popular niches, then adds combinations of your own words (like #londoncoffee). Everything runs in your browser — no AI and nothing is sent to a server.
Should I use the same hashtags on every platform?
Not quite. Instagram and TikTok reward several niche hashtags, LinkedIn works best with 3–5 professional ones, and on X one or two is plenty. Trim the list for each network before you post.
Are popular hashtags like #viral or #fyp worth using?
Broad tags have huge competition, so your post is quickly buried. Use them sparingly and rely on specific tags that describe your content, location and audience.
