How to Use YouTube Tag Extractor to Boost Your Video SEO
Want to rank higher on YouTube? Learn how to use a YouTube tag extractor to discover the hidden tags your competitors use and apply them to your own videos.

Every video on YouTube has a secret. Hidden behind the screen, invisible to normal viewers, is a list of special words called tags. These tags are what YouTube uses to understand your video and decide who to show it to.
Successful YouTubers know how to use tags strategically. And now, with a YouTube Tag Extractor tool, you can see exactly what tags any video is using โ even your biggest competitors!
This guide will teach you everything about YouTube tags and how to use our free extractor tool to supercharge your video SEO.
What Are YouTube Tags?
When you upload a video to YouTube, you can add tags to it. Tags are short keywords or phrases that describe your video's content.
For example, if you upload a cooking video about "How to Make Biryani," you might add tags like:
- biryani recipe
- how to make biryani
- chicken biryani
- Indian cooking
- rice recipes
- biryani at home
YouTube reads these tags to understand:
- What is this video about? The tags help YouTube categorize your content
- Who should see this video? Tags help match your video to the right search queries
- What related videos should appear next? Videos with similar tags appear in the "Up next" section
Why Are Competitor Tags Important?
The best strategy for growing on YouTube is understanding what is already working. If a competitor's video has 1 million views on "how to make biryani," they clearly used the right tags.
By extracting their tags, you can:
- โ Discover high-performing keywords you hadn't thought of
- โ Understand what phrases viewers actually search for
- โ Find niche tags that have less competition but still drive views
- โ Build a comprehensive tag strategy based on proven data
Instead of guessing which tags to use, you use the tags that ALREADY work for popular videos.
How Does a YouTube Tag Extractor Work?
YouTube embeds the tags for each video in the page's code. When you view a YouTube video, your browser downloads the HTML code of the page, including the hidden metadata section where tags are stored.
A YouTube Tag Extractor tool reads this HTML code and extracts just the tags section, displaying them in a clean, easy-to-copy list.
SmartToolsWala's YouTube Tag Extractor does this automatically in seconds โ you just paste the video URL and click extract.
Step-by-Step: How to Use SmartToolsWala's YouTube Tag Extractor
Step 1: Find a Video to Extract Tags From
Go to YouTube and find a successful video in your niche. Look for videos that:
- Have many views (100K+) on a topic you want to rank for
- Were uploaded recently (within the last 1-2 years) for current relevance
- Are from channels that are not mega-corporations (smaller channels with high view counts indicate the tags are doing heavy lifting)
Copy the video's URL from your browser's address bar.
Step 2: Open SmartToolsWala Tag Extractor
Go to SmartToolsWala and open the YouTube Tag Extractor tool.
Step 3: Paste the URL
Paste the YouTube video URL into the input field. Click the "Extract Tags" button.
Step 4: View and Copy the Tags
Within seconds, the tool extracts all the tags the video creator added. You'll see a clean list of all their tags.
Step 5: Use the Tags Strategically
Don't simply copy every tag blindly. Instead:
- Identify the most relevant ones for YOUR video topic
- Look for patterns โ which tags appear in multiple successful videos?
- Find niche-specific tags that are specific enough to not have too much competition
- Combine with your own ideas โ add tags that are unique to your specific video angle
What to Do With Extracted Tags
Once you have a list of tags from successful videos:
Create Your Tag List
YouTube allows up to 500 characters of tags. That's space for roughly 15 to 25 tags depending on length.
Build your tag list with a mix:
- 3-5 broad tags (the main topic): "biryani recipe," "Indian food"
- 5-8 specific tags (the video angle): "chicken biryani home recipe," "restaurant style biryani"
- 3-5 long-tail tags (very specific phrases): "how to make biryani at home without dum"
- 3-5 related topic tags (similar content): "rice dishes," "Indian dinner recipes"
Order Your Tags Wisely
Put your most important, specific tags first. YouTube gives slightly more weight to the first few tags.
Don't Keyword Stuff
Using 100 irrelevant tags thinking "more is better" is a mistake. YouTube may penalize videos for tag stuffing โ using tags that have nothing to do with the video. Only use tags that are genuinely relevant.
Tags vs. Title vs. Description: What Matters More?
Many new YouTubers think tags are the most important ranking factor. In reality:
Most important: Video title, thumbnail click-through rate, watch time, audience retention Very important: Video description (first 2-3 lines) Important (but less than before): Tags
Tags still matter, especially for discovery through related videos and some search queries. But they work best when they complement a strong title and engaging content that people actually watch.
Frequently Asked Questions
Can I extract my own video's tags to check them?
Yes! Paste your own video URL into the extractor. It's a great way to audit your existing tags and compare them to competing videos.
Why does the tool show zero tags for some videos?
Not all creators use tags. Some (especially large channels) rely primarily on titles, descriptions, and YouTube's AI to rank their videos. If a popular video has zero tags, it means the creator chose not to add them.
Are tags visible to normal YouTube viewers?
No. Regular viewers watching on YouTube do not see tags. Tags are only visible in the video's backend settings (for the creator) or through tools like ours that read the page's HTML code.
How often should I update my video tags?
If a video is performing well, don't change its tags โ you might disrupt what's working. If a video is underperforming, consider updating tags based on new keyword research or competitor analysis.
