The YouTube hashtag tool from Postiz is a free AI hashtag generator built to help creators, educators, and brands surface the exact tags that push videos and Shorts into the right search results and Browse feeds. Paste your video title, description, or topic idea, and the generator returns a clean, ranked list of YouTube hashtags you can drop straight into your description. Every suggestion is scored with YouTube’s real ranking signals in mind, including the three hashtags that appear directly above the title, the fifteen-hashtag indexing limit, and the platform’s strict rules around spam and stuffing.
Whether you are growing a long-form channel, publishing Shorts daily, or running a brand channel with weekly uploads, the right hashtags are one of the cheapest discovery wins on YouTube. This free YouTube hashtag generator removes the guesswork by giving you a mix of branded, topical, and Shorts-specific tags in seconds, so you can focus on shooting and editing instead of digging through competitor descriptions.
YouTube hashtag rules you need to know
YouTube handles hashtags differently from TikTok or Instagram, and understanding the platform’s rules is the fastest way to avoid accidentally hiding your own video. Before you use the YouTube hashtag generator, keep these core rules in mind:
- Top three hashtags show above the title. The first three hashtags you list in your video description are displayed as clickable links above the video title. These are the most visible hashtags on your video, so put your highest-intent tag first.
- Fifteen hashtags max are indexed. YouTube only reads and indexes the first fifteen hashtags in your description. Anything beyond that is ignored, and in some cases treated as a signal of spam.
- More than fifteen hashtags can cause your video to drop. If you stuff more than fifteen hashtags, YouTube may ignore all of them and can even remove the video from search or uploads entirely. Quality beats quantity every time.
- No misleading, hateful, or harassing hashtags. YouTube’s community guidelines apply to hashtags. Tags must match the content and must not target individuals or groups.
- Hashtags in the title replace your top three. If you include a hashtag inside the video title itself, it counts toward the limit and takes the top slot above the title.
Our AI hashtag tool follows these rules automatically. It returns between three and fifteen suggestions, avoids banned or spammy tags, and orders them by estimated discovery value so your top three carry the most weight.

Hashtag strategies that actually move the needle
Branded hashtags
Branded hashtags tie a series, channel, or company name to every video you publish. Examples include #MrBeast, #MKBHD, or a show name you own such as #BehindTheBuild. Branded tags are low volume on day one, but they compound over time. Viewers who click a branded hashtag land on a hub of all your videos that use it, which boosts session time and subscribers. The AI generator will suggest a branded slot in your top three whenever you feed it a recognizable channel or series name.
Topical hashtags
Topical hashtags describe what the video is about in plain language. If you publish a camera review, topical tags might include #CameraReview, #MirrorlessCamera, and #Photography. These are the workhorses of YouTube discovery, because they match how real viewers search and browse. The generator blends broad tags with two or three narrow long-tail tags so you compete where you can actually win.
Shorts-specific hashtags
Shorts have their own hashtag culture, and the algorithm rewards tags that clearly signal vertical, short-form content. The tool recognizes Shorts prompts and prioritizes tags like #Shorts, #YouTubeShorts, and niche Shorts tags such as #CookingShorts or #FitnessShorts. If you are mixing long-form and Shorts on the same channel, keeping a consistent Shorts tag set helps YouTube route your content to the Shorts feed instead of the standard watch page.
Use cases for the YouTube hashtag tool
- Full-time creators. Save time researching tags for every upload and keep a consistent hashtag library across a channel. The generator is perfect for creators publishing multiple videos per week who need repeatable, on-brand hashtag sets.
- Educators and course creators. Tutorial channels thrive on long-tail topical tags. Paste a lesson title and get tags that map to how students actually search, such as #ExcelTutorial, #LearnPython, or #BeginnerGuitar.
- Shorts creators. Vertical creators posting daily Shorts can generate a balanced Shorts tag stack that mixes the flagship #Shorts tag with niche Shorts tags to unlock more precise recommendations.
- Brand and agency channels. Brands managing multiple channels can standardize branded hashtag usage, and agencies can generate client-ready tag sets without manual research for every brief.
- Podcasters repurposing clips. If you publish podcast clips to YouTube, the tool gives you a tag set that signals both topic and format, helping your clips surface to podcast fans on YouTube.
Best practices for YouTube hashtags
- Lead with your strongest three. The first three tags are the only ones that appear above the title, so use them for your highest-value, highest-intent hashtags.
- Stay under fifteen. Never go above fifteen hashtags in a description. The extra tags are ignored and can trigger YouTube’s spam detection.
- Match the tag to the video. YouTube penalizes misleading tags. If your video is not about #Bitcoin, do not include it even if the search volume is tempting.
- Mix broad and narrow tags. Pair one or two big-volume tags with three to five specific long-tail tags. The long-tails are where new channels actually rank.
- Keep a Shorts tag stack. For vertical content, always include #Shorts plus a niche Shorts tag.
- Refresh quarterly. Hashtag trends shift. Re-run the generator for evergreen videos every few months and update the description if a better tag emerges.
- Watch YouTube Studio. The traffic source report shows which hashtags are driving impressions and clicks. Double down on the winners and prune the rest.
Frequently asked questions
How many hashtags should I use on a YouTube video?
Three to fifteen is the sweet spot. Three is the minimum to fill the slots that appear above your title, and fifteen is the hard indexing limit. Most high-performing videos use between five and ten targeted hashtags.
Can I use the same hashtags on every video?
You can reuse branded and core channel hashtags on every upload, and you should. Rotate the topical and Shorts-specific tags to match each video’s subject.
Do hashtags help Shorts more than long-form videos?
Hashtags help both, but they are especially valuable on Shorts because the Shorts feed leans heavily on tag-based categorization. Long-form videos benefit most from topical hashtags tied to search intent.
Are YouTube hashtags a ranking factor?
YouTube uses hashtags as a categorization signal, not a direct ranking factor like watch time or click-through rate. Good hashtags help YouTube surface your video to the right audience, which then improves the engagement signals that actually drive ranking.
Is the YouTube hashtag tool free?
Yes. The generator is free to use and does not require a Postiz account for single generations. Creating a free Postiz account unlocks saved hashtag sets, scheduling, and cross-platform publishing.
