How YouTube Hashtags Work in

YouTube hashtags are clickable keywords that start with the # symbol. You add them to your video title or description to help viewers discover your content through topic browsing. Unlike hidden tags, hashtags are visible to viewers and the first 3 appear as blue links directly above your video title. They work for both regular videos and YouTube Shorts.

How Hashtags Help Your Videos Get Discovered

Three ways hashtags drive viewers to your content.

Clickable Topic Pages

When a viewer clicks a hashtag above your title or in your description, they land on a page showing all videos using that hashtag. This gives your video a chance to be seen by people browsing topics, not just searching keywords.

Visible Above Your Title

The first 3 hashtags you use appear as blue clickable links directly above your video title on the watch page. This prime real estate helps viewers instantly understand your video topic and discover related content.

Shorts Discovery

For YouTube Shorts, hashtags play an even bigger role. The algorithm uses hashtags to match your Short with interested viewers in the Shorts feed. Niche-specific hashtags help your Short reach the right audience instead of getting lost in the general feed.

YouTube Hashtag Rules You Need to Know

Follow these rules to avoid having your hashtags ignored or your video flagged.

3 Shown above title
3-5 Recommended per video
15 Maximum before ignored
0 Spaces allowed in a hashtag
Important

If you use more than 15 hashtags on a single video, YouTube will ignore all of them. Your video may also be removed from search results. Stick to 3 to 5 well-chosen hashtags. Our generator limits your selection to 15 and warns you if you approach the limit.

Hashtags vs Tags: Use Both

They serve different purposes and complement each other.

Hashtags (Visible)
  • Placed in title or description with #
  • Clickable by viewers
  • Create browsable topic pages
  • First 3 appear above video title
  • Use 3-5 per video
Tags (Hidden)
  • Added in the video settings metadata field
  • Invisible to viewers
  • Help YouTube categorize internally
  • Catch misspellings and variations
  • 500-character limit, use 8-15
Use Both Together

For maximum discoverability, use 3 to 5 hashtags in your title or description AND fill out the hidden tags field in video settings. Our YouTube Tag Generator creates optimized hidden tags, while this Hashtag Generator creates the visible hashtags. Together, they cover both discovery channels.

Hashtag Strategy for YouTube Shorts

Shorts rely on hashtags more than long-form videos.

YouTube Shorts are discovered primarily through the algorithm, not search. Hashtags help the algorithm categorize your Short and match it with the right audience. A well-chosen set of hashtags can mean the difference between 100 views and 100,000 views on a Short.

  • Always include 2 to 4 niche hashtags that describe your specific content topic
  • Mix trending and evergreen to ride current trends while building lasting discoverability
  • Put hashtags in the description to keep your Short title clean and focused
  • Use our Shorts toggle to get hashtags specifically optimized for short-form content

Common Hashtag Mistakes to Avoid

These errors can hurt your video's discoverability.

  • Using more than 15 hashtags causes YouTube to ignore all of them
  • Spaces inside hashtags break them (#Minecraft Tips becomes just #Minecraft)
  • Only generic hashtags like #YouTube or #Video have too much competition to be useful
  • Misleading hashtags can get your video removed from search
  • Same hashtags on every video signals low-effort content to the algorithm

Frequently Asked Questions

How does the YouTube Hashtag Generator work?

Our hashtag generator queries real YouTube search data using Google's autocomplete API. When you enter a topic, it expands it with common prefixes and suffixes to find what real viewers are searching for. Results are converted to hashtag format and categorized into trending, niche, and long-tail categories for a balanced hashtag strategy.

Is this hashtag generator really free?

Yes, 100% free with no signup required. We use Google's public autocomplete data which costs us nothing to query. There are no hidden charges, premium tiers, or credit limits. Generate as many hashtag sets as you need.

How many hashtags should I use on a YouTube video?

YouTube recommends 3 to 5 hashtags per video. The first 3 hashtags you use appear as clickable blue links directly above your video title. If you use more than 15 hashtags, YouTube will ignore all of them entirely. Stick to 3 to 5 well-chosen hashtags for the best results.

What is the difference between hashtags and tags?

Hashtags are visible text placed in your title or description with the # symbol. They create clickable topic pages and the first 3 appear above your video title. Tags are hidden metadata added in the tags field that help YouTube's algorithm categorize your video. Both serve different purposes and should be used together for maximum discoverability.

Where should I put hashtags on YouTube?

You can place hashtags in your video title or description. If placed in the title, the first 3 become clickable links above the title. If placed in the description, the first 3 still appear above the title. For regular videos, most creators put them at the end of the description. For Shorts, placing them in the title is more common.

Do hashtags work differently for YouTube Shorts?

Hashtags play an even bigger role for Shorts than for regular videos. The algorithm uses hashtags to match your Short with interested viewers in the Shorts feed. Niche-specific hashtags help your Short reach the right audience instead of getting lost in the general feed. Always include 2 to 4 niche hashtags on every Short.

What happens if I use more than 15 hashtags?

If you use more than 15 hashtags on a single video, YouTube will ignore all of them. Your video may also be removed from search results. Our generator limits your selection to 15 and warns you as you approach the limit with a visual progress bar.

What does the Hashtag Checker do?

The Hashtag Checker analyzes your existing hashtags for count, formatting issues (like spaces inside hashtags), which hashtags will be visible above your title, and provides a YouTube title preview showing exactly how your first 3 hashtags will appear to viewers.

Can I use the same hashtags on every video?

Using identical hashtags on every video signals low-effort content to the algorithm. While you can reuse 1 to 2 core niche hashtags, the majority should be specific to each video's topic. Our generator creates fresh hashtags based on your specific video topic each time you use it.

Should I use #Shorts on my YouTube Shorts?

YouTube has stated that #Shorts is no longer required for a video to be recognized as a Short. However, many creators still include it as it can help with discoverability through the #Shorts hashtag topic page. It does not hurt to include it, but focus your hashtag slots on niche-specific terms first.
