How Many Hashtags Should You Use on YouTube Shorts?
Find out the optimal number of hashtags for YouTube Shorts based on platform behavior, creator data, and discoverability strategies.

Hashtags on YouTube Shorts serve a different purpose than on Instagram or Twitter. While some creators load their descriptions with dozens of tags, the YouTube algorithm processes them in specific ways that reward precision over volume. This guide breaks down how YouTube uses hashtags, what the data suggests about optimal counts, and how to build a hashtag strategy that actually improves your Shorts performance.
1. How YouTube processes hashtags
YouTube reads hashtags from your title and description to categorize content. The platform displays up to three hashtags above your video title on desktop. Hashtags help YouTube understand context, especially for new channels where the algorithm has limited viewing history to work with. However, YouTube has stated that excessive tagging does not improve discovery and may even be flagged as spam.
2. The optimal number: 3 to 5 hashtags
Based on creator surveys and platform behavior analysis, the sweet spot for YouTube Shorts is 3 to 5 relevant hashtags. This gives the algorithm enough context to categorize your content without appearing spammy. Place 1-2 in the title if they fit naturally, and put the rest in the description. Each hashtag should be specific to your content rather than generic trending tags.
- Use 3-5 highly relevant hashtags per Short
- Put 1-2 in the title when they read naturally
- Place remaining hashtags in the description
- Avoid generic tags like #viral or #trending unless truly relevant
3. Choosing the right hashtags
Effective hashtags combine broad category tags with niche-specific ones. For a cooking Short, you might use #cooking (broad), #mealprep (category), and #chickenrecipes (niche). Research what hashtags successful creators in your niche use. YouTube's search autocomplete is a free tool that shows what people actually search for. Avoid copying the same hashtag set across all videos — vary them to match each video's specific content.
4. Hashtag placement and formatting
YouTube displays the first three hashtags from your description above the video title on desktop. Place your most important hashtags first. Use camel case for multi-word hashtags to improve readability and accessibility (#MealPrep instead of #mealprep). Do not use spaces or special characters within hashtags. Keep them concise — long hashtags are hard to read on mobile screens.
5. Common hashtag mistakes
The biggest mistake is hashtag stuffing: loading your description with 20 or more tags in hopes of gaming the algorithm. This does not work and can trigger spam filters. Another mistake is using irrelevant trending hashtags to chase views. If your cooking video uses #gaming hashtags, YouTube may initially show it to gaming audiences, who will swipe away quickly, hurting your retention metrics.
- Do not stuff more than 15 hashtags (YouTube may ignore them)
- Avoid irrelevant trending tags that hurt audience retention
- Do not use the same set on every video
- Skip branded hashtags until your brand is recognizable
6. Measuring hashtag performance
YouTube Analytics does not directly show hashtag-level traffic, but you can observe patterns. Compare Shorts with different hashtag strategies over a few weeks. Look at traffic sources — if Search and Browse traffic increases after refining your hashtags, your strategy is working. Tools like TubeBuddy and vidIQ offer hashtag scoring features that estimate competition and search volume for specific tags.
FAQ
Can I use hashtags in YouTube Shorts comments?
You can type hashtags in comments, but they do not affect your video's discoverability. Only hashtags in the title and description are processed by the algorithm.
Do hashtags work differently for Shorts vs long-form?
The processing mechanism is similar, but Shorts rely more heavily on the Shorts Feed algorithm where hashtags play a smaller role than watch time and swipe-away rate. Hashtags matter most for Search and Browse discovery.
Should I use hashtags or keywords in my Shorts title?
Use both. Natural language keywords in the title help with Search SEO. Adding 1-2 hashtags to the title gives the algorithm additional categorization signals. Write for humans first, optimize for the algorithm second.
