YouTube Tag
Extractor + Tag Diff
See the hidden tags of any video — then run the only feature competitors don't have: Tag diff. Two URLs in, and you get the tags you share, the tags only you use, and the answer to the real question: what do they have that I don't? Official API data, Shorts included.
- ● Tag diff: you vs a competitor
- ● Official API data, not scraping
- ● 500-char budget analysis
- ● Bulk mode · 25 URLs → CSV
Tags are hidden on the watch page but public in the API. You'll get the full list, a 500-character budget analysis and copy/export actions.
Two URLs → shared tags, your unique tags, and the list that matters: what they rank with that you're not using. One-click copy of exactly that list.
Tags were removed from YouTube's watch page years ago — the only way to see them is the Data API, which is exactly what this extractor queries.
Paste up to 25 competitor URLs and get a merged frequency table: the tags that appear on 8 of 10 videos are the vocabulary of your niche.
No account, no extension, no watermark. A free alternative to the tag viewers in TubeBuddy and vidIQ.
Reference
Hidden tags — the facts that matter
Everything this extractor shows is public API data — the same snippet.tags array any developer can request. What changed over the years is only who bothers to look.
| Fact | Status | What it means for research |
|---|---|---|
| Watch-page visibility | Removed in 2012 | Viewers can't see tags — but the API can, on any public video |
| Data source | snippet.tags (API v3) | Official data, not scraping — exact, complete, current |
| Combined budget | 500 characters | The analysis panel shows how much of it a video spends |
| Ranking weight | Minimal (per YouTube) | Tags map synonyms and misspellings — read them as vocabulary, not magic |
| Shorts | Same tags field | /shorts/ URLs extract exactly like long-form |
| Legality | Public data | Everyone can see everyone's — that's why tag research is standard practice |
How to
See any video's tags — then out-tag it
Watch, Shorts, live or youtu.be — the live check in the hero confirms the video ID before you extract.
The full snippet.tags list, chip by chip — copy as a comma list for Studio, one-per-line for sheets, or CSV.
Switch to the diff tab, paste a competitor's URL and read the three columns — 'only theirs' is your to-do list.
Bulk mode merges up to 25 videos into a frequency table: tags on 8 of 10 videos are the niche's core vocabulary.
Who it's for
Learn the vocabulary of your niche
Creators extract tags from the top 5 videos on their target topic before writing their own — the overlap between those lists is the core vocabulary YouTube already associates with the subject.
SEO researchers run bulk mode across a competitor's recent uploads to map their tagging strategy over time: which evergreen tags persist, which trend tags rotate in and out.
Channel managers audit their own back catalogue — the budget analysis makes under-tagged uploads (50 of 500 characters used) visible at a glance.
Tool builders export CSV instead of wrestling with API quota, key management and the snippet.tags edge cases.
Two ways to research
Extract one video vs diff two of them
Extraction tells you what a video ranks with. The diff tells you what to do about it — the difference between reading a competitor's homework and knowing which answers you're missing.
One video's tags
The classic move: reveal what's hidden. Every URL format works, and the output is shaped for wherever it goes next.
Copy formats
- Studio
tag one, tag two, tag three (comma list) - Spreadsheet
one tag per line - Data work
CSV with per-tag length column - Analysis tab
500-char budget, multi-word share, lengths
Your video vs theirs
The signature: two URLs, three columns, one actionable list. Matching is case-insensitive, so "DIY Desk" and "diy desk" count as the same tag.
How to read the columns
Only theirs— vocabulary they rank with that you skipped: the to-do listShared— the common ground; a high count means you already speak the niche's languageOnly yours— your differentiators; keep the deliberate ones, question the accidental onesSimilarity %— Jaccard overlap of both sets; ~0% usually means the videos target different searches entirely
Which should I use?
Scouting a topic before you upload — Extract the top-ranking video and start from its vocabulary. Already published and losing to a specific video — Tag diff against it, copy "only theirs", and merge the relevant ones into your set in Studio. Mapping a whole niche — bulk mode across the top 10–25 results.
One tool, every intent
However you searched for it, this is the page
People land here wanting to see a YouTube video's tags, to copy YouTube tags, to find a tags viewer without a Chrome extension, or to compare their tags with a competitor's. Same workflow: paste, extract, diff, copy.
A tags viewer without the extension
Most "tag viewer" results push a Chrome extension with broad page permissions. This page needs none of that — the tags come from the official API, in any browser, mobile included.
Copy a video's tags, correctly
Copy-pasting a competitor's full set verbatim wastes budget on their channel name and misleads YouTube about your content. Extract to learn the vocabulary, diff to find the gaps, then rebuild your own set with the Tag Generator.
Why "hidden" doesn't mean secret
YouTube removed tags from the watch page in 2012 to stop keyword spam — but left them public in the Data API. Every serious channel reads competitors' tags; this page just removes the API key ceremony.
From one video to the whole niche
One video is an anecdote; 25 are a strategy. Bulk mode's frequency table shows which tags persist across a channel's uploads (evergreen) and which rotate with trends — the difference between their vocabulary and their luck.

FAQ
Frequently asked questions
How do I see the tags of a YouTube video?+
Paste the video URL above. Tags aren't shown anywhere on YouTube's watch page — creators enter them in Studio and they stay hidden from viewers — but they're public data in the YouTube Data API, which is exactly where this extractor reads them from.
What is the Tag diff?+
This tool's signature feature: paste your video and a competitor's, and the diff splits the two tag sets into three columns — only yours, shared, and only theirs. 'Only theirs' is the actionable list (the vocabulary they rank with that you're missing), and it copies with one click. A similarity score shows how close the two strategies are overall.
Is this YouTube tag extractor free?+
Yes — 100% free, no signup, no Chrome extension and no daily cap that matters in practice. It's a simple alternative to the tag viewers bundled into paid suites like TubeBuddy and vidIQ, and it works on Shorts URLs too.
Why does a video show no tags?+
Many creators simply don't set any — tags have limited ranking weight nowadays, and YouTube itself says they play a minimal role for discovery. If the API returns an empty list, the video genuinely has no tags; nothing is being hidden from you.
Are video tags really public?+
Yes. They're hidden from the watch page UI, but the Data API exposes the full snippet.tags array of any public video. That's also why 'tag stealing' is common competitor research — everyone can see everyone's tags.
