Finding the right keywords for a YouTube video can take almost as much time as creating the video itself. A YouTube tag generator can speed up that process by turning a topic, title, or primary keyword into a list of related tags.
However, there is an important distinction that many articles overlook: YouTube tags are no longer a major ranking factor. YouTube itself says that tags are mainly useful for correcting common misspellings, while the title, thumbnail, and description play a more important role in discovery. Google Help Centre
That doesn’t mean tag generators are useless. They can still be helpful for finding keyword variations, misspellings, related phrases, and ideas that you may have overlooked.
What Is a YouTube Tag Generator?
A YouTube tag generator is a tool that creates keyword and tag suggestions based on your video topic, title, or target keyword.
For example, if you’re creating a video about “how to start a YouTube channel,” a tag generator might suggest variations such as:
- how to start a YouTube channel
- start a YouTube channel
- YouTube channel for beginners
- YouTube tips for beginners
- how to create a YouTube channel
- YouTube channel setup
Instead of brainstorming every variation manually, you can use a generator to create an initial list and then remove anything irrelevant.

might produce several variations based on what users are searching for.

How to Use a YouTube Tag Generator
Using a tag generator is straightforward.
Step 1: Choose Your Main Keyword
Start with the primary topic of your video.
For example:
“Instagram marketing tips”
Step 2: Enter It Into a Tag Generator
Put your topic or video title into your chosen tool.
Step 3: Review the Suggestions
Don’t automatically copy every generated tag.
Remove tags that:
- Don’t accurately describe your video
- Are too broad
- Are unrelated
- Were generated simply because they’re popular
- Could mislead viewers
Step 4: Keep Relevant Variations
Prioritize variations closely connected to your video’s actual topic.
For example:
Primary keyword:
Instagram marketing tips
Relevant variations:
- Instagram marketing
- Instagram marketing strategy
- Instagram marketing tips
- Instagram growth strategy
- Instagram marketing for beginners
Step 5: Add Them in YouTube Studio
YouTube provides a dedicated Tags field in the video settings. For a new upload, you can find it under Details → More Options. For an existing video, go to Content → select the video → Show More. Google Help Centre
How Many YouTube Tags Should You Use?
There’s no need to fill the tag field simply because you can.
YouTube explicitly says that tags play a minimal role in discovery and are primarily useful for common misspellings. Google Help Centre
A better approach is to use a small collection of highly relevant tags rather than stuffing dozens of unrelated keywords into your metadata.
For example, if your video is about:
“How to Edit YouTube Videos on CapCut”
your tags could include:
- how to edit YouTube videos
- CapCut video editing
- edit YouTube videos with CapCut
- CapCut tutorial
- YouTube video editing
- video editing for beginners
There’s little reason to add generic tags such as “viral,” “YouTube,” “video,” or “trending” unless they’re genuinely relevant to the video’s topic.
YouTube Tags vs. Hashtags
These two are often confused.
YouTube Tags
Tags are metadata added through YouTube Studio. Viewers don’t normally see them.
Their main current use is helping YouTube understand variations and misspellings associated with your content. Google Help Centre
YouTube Hashtags
Hashtags use the # symbol and can appear in your video’s title or description.
For example:
#YouTubeSEO
#VideoMarketing
#YouTubeTips
They’re a separate feature from the hidden Tags field.
Do YouTube Tags Still Matter for SEO?
Yes, but much less than many creators think.
YouTube’s own documentation states that the title, thumbnail, and description are more important metadata for discovery, while tags play a minimal role. Tags are particularly useful when a topic or name is commonly misspelled. Google Help Centre
This means you shouldn’t spend 30 minutes trying to create the perfect tag list while spending only two minutes on your title and thumbnail.
A better priority is:
Topic → Title → Thumbnail → Video quality → Description → Tags
Tags should be treated as a supporting optimization step, not the foundation of your YouTube SEO strategy.
What Makes a Good YouTube Tag?
A good tag should accurately describe the video.
1. Relevant
The tag should have a direct relationship with the video.
2. Specific
Specific phrases are generally more useful than extremely broad terms.
3. Natural
Use phrases that genuinely describe what viewers will find in the video.
4. Include Variations
Consider close variations, alternate spellings, abbreviations, or different ways people might search for the same topic.
5. Avoid Misleading Tags
Don’t add popular keywords simply because they generate a lot of searches.
RapidTags itself recommends starting with the actual video topic and keeping tags relevant rather than using random broad keywords. Rapidtags
Common YouTube Tag Generator Mistakes
Using Every Suggested Tag
A generator produces ideas, not a finished tag strategy.
Always review the suggestions manually.
Targeting Completely Unrelated Keywords
A popular keyword isn’t automatically a good keyword.
If your video is about Photoshop tutorials, adding unrelated tags such as “iPhone,” “football,” or “Taylor Swift” won’t make the video more discoverable to the right audience.
Ignoring Misspellings
This is one of the situations where tags can still be particularly useful because YouTube specifically identifies common misspellings as a use case. Google Help Centre
Putting Tags in the Description
Don’t paste a large block of keywords into your description.
YouTube specifically warns that excessive tags in the description violate its spam, deceptive practices, and scams policies. Google Help Centre
Spending Too Much Time on Tags
This is perhaps the biggest mistake.
If you have one hour to optimize a video, spending most of that hour generating tags isn’t a good use of your time.
Your title, thumbnail, content quality, and viewer satisfaction deserve much more attention.

Final Thoughts
A YouTube tag generator can save time and help uncover relevant keyword variations, but tags shouldn’t be treated as a magic ranking button.
Tools like vidIQ, TubeBuddy, RapidTags, and Keyword Tool are useful for different parts of the research process. The smartest approach is to use them to generate ideas, manually filter those ideas, and then focus most of your optimization effort on the things that matter more.
And remember: according to YouTube itself, tags play a minimal role in discovery. Use them as supporting metadata—particularly for relevant variations and misspellings—rather than relying on them to make an otherwise weak video rank. Google Help Centre
For most creators, the winning workflow is simple: research the topic → create a strong video → write a compelling title → design a good thumbnail → optimize the description → add a few highly relevant tags.
