YouTube Hashtag Generator

YouTube's official rule is a 15-hashtag cap per video — if you exceed it, YouTube ignores all of them and may shadow-flag the upload. Our generator outputs exactly 15 hashtags by default, split as 5 trending + 7 niche + 3 long-tail, so you're at the cap without overflowing. Place 3 in the title (max) or at the very top of the description — those three show above the video title in the YouTube UI and are the highest-leverage hashtag slots on the platform.

Description is the safer default. Adding 1–3 hashtags to the title can boost CTR when the hashtag is genuinely trending in your niche, but most title hashtags hurt readability and dilute the keyword in the click test. The bulletproof setup is: 0 hashtags in the title, 3 prominent hashtags on the first line of the description (these become the clickable trio above the title in the YouTube player UI), and the remaining 12 at the bottom of the description below the CTA and chapters.

Yes — Shorts rely on hashtags much more than long-form for discovery. #shorts itself is the single highest-leverage hashtag for the Shorts shelf and should always be the first hashtag on every Short you upload. Beyond that, Shorts hashtags should lean broad/trending (where the Shorts feed surfaces them) while long-form hashtags can be more niche and topical. Set 'short' as the video format in our generator and the trending bucket will be weighted toward Shorts-feed-friendly tags.

Hashtags help with discovery on the hashtag feed (when a viewer clicks #fitness, your video can appear there) but they have minimal effect on regular YouTube search ranking. For search ranking, the bigger levers are the title, the first 150 characters of the description, and your CTR + watch-time signals. Use this hashtag generator alongside the YouTube Description Generator to cover both the discovery and the SEO sides in one pass.

1–3 anchor hashtags (your channel name, your main niche, #shorts for Shorts) are fine on every video — they help build a brand cluster. The other 10–12 hashtags should change per video to match the specific topic. Reusing the entire 15-hashtag set on every upload won't get you banned but it does waste hashtag slots that could be capturing topic-specific reach. Re-run our generator for every new upload — it takes 5 seconds and unlocks 10+ topic-specific hashtags every time.
