Frequently Asked Questions
How does the hashtag generator work without an API key?
It uses a hand-curated in-browser dictionary of ~290 hashtags across 13 popular YouTube categories. We tokenize your input, match against category aliases, and rank by relevance — no third-party APIs involved.
How many hashtags should I use on YouTube?
YouTube indexes only the first 15 hashtags in your description. Adding more is wasted effort and can trigger spam flags. Aim for 8-15 highly relevant tags.
What's the difference between generic, niche, and mixed style?
Generic favors popular short tags like #shorts and #viral that maximize reach. Niche favors long-tail tags like #100daysofcode for targeted audiences. Mixed balances both — usually the best default.
Does it work for YouTube Shorts?
Yes — Shorts use the same hashtag system as regular videos. The generator includes #shorts and related Shorts-specific tags in the generic and mixed pools.
Why are some hashtags marked as 'not indexed'?
When you generate more than 15 tags, the ones beyond position 15 won't be indexed by YouTube. The tool flags them so you can prune to the 15 most valuable.
Can I add custom hashtags from my keywords?
When the dictionary doesn't match your topic well, the generator falls back to camelCasing your keywords as hashtags. So '3D printing tutorial' becomes #3dprinting #tutorial alongside generic boosters.
Are these hashtags trending right now?
The dictionary includes evergreen, high-volume hashtags that have remained relevant on YouTube — but they aren't real-time trend data. Pair these with manual research for breaking trends.
Is this free to use?
Yes — completely free, no signup, no API key, no rate limits.
