What Are YouTube Tags Used For?
Tags are keywords that help YouTube understand what your video is about. Extracting them in bulk helps with:
How to Use Extracted YouTube Tags for Keyword Research
A single video's tag list doesn't tell you much on its own. The value shows up once you extract tags from several videos on the same topic and start comparing them — that's when patterns emerge that a single title or description won't reveal. Here's a simple workflow for turning raw tags into actual keyword research:
Find videos covering your target topic
Start with the search term you actually care about, then run the Tag Extractor on 5–10 of the top-ranking videos for it — not just the #1 result. A single video's tags can be an outlier or just a habit of that particular creator, but a pattern that shows up across several unrelated channels is far more likely to mean something.
Look for repeated topic terms
Once you've extracted tags from a handful of videos, scan the lists for terms that keep resurfacing. If multiple creators independently tag their videos with the same phrase, that's a decent signal of how people actually describe the topic — as opposed to how you assume they describe it based on your own vocabulary.
Separate broad and specific keywords
Sort what you find into rough buckets so you know what to do with each one:
- •Broad topic terms — the general category a video falls under
- •Long-tail phrases — specific, multi-word variations with lower competition
- •Product or brand names — useful if your content references specific items
- •Creator or channel names — relevant for reaction, review, or comparison videos
- •Common variations and misspellings — alternate wordings people search for
Use the Compare Videos tab
Paste two competing videos into the Compare tab to line their tags up side by side. The shared tags show you the baseline vocabulary everyone in that niche already uses — useful, but not a differentiator. The tags unique to just one video are usually more interesting, since they often point to a sub-topic, angle, or keyword gap the other video missed entirely.
Don't blindly copy every tag
This is the part that's easy to get wrong. Treat extracted tags as research data and inspiration, not a ready-made list to paste into your own upload. Copying a competitor's exact tags won't reproduce their ranking, because tags are one minor signal among many — title, thumbnail, watch time, and the video itself carry far more weight. Use what you learn here to sharpen your title and description, not as a shortcut around making a better video.
None of this requires extracting tags from dozens of videos. A handful of well-chosen, top-ranking competitors is usually enough to spot the terms worth paying attention to — the goal is a clearer picture of how a topic is talked about, not a spreadsheet you never look at again.
Why Compare Tags Between Two YouTube Videos?
Looking at one video's tags tells you what that creator chose to add. Comparing two videos tells you something more useful: what they agree on, and where they diverge. That contrast is where the actual insight lives.
The shared tags between two videos on the same topic usually represent the baseline vocabulary for that niche — terms so standard that competing creators landed on them independently. The tags unique to one video are typically more revealing, since they can point to a sub-topic, format, or keyword the other video overlooked. The overlap percentage itself is a quick gut-check: a very high overlap suggests two videos are targeting nearly identical ground, while a low one suggests they're covering the same broad topic from different angles.
In practice, this is most useful before you publish: run your planned topic against two or three top-ranking videos in the same space, see where your tag list already lines up, and note anything they cover that you hadn't considered — then decide for yourself whether it belongs in your title, description, or the video itself.
