Twenty good tags, ranked by relevance.

Type a topic, get 15-20 topical tags ordered specific to broad. Toggle the ones you don't want, copy the rest, paste into YouTube Studio.

What tags do (and what they don't)

YouTube's ranking system is, in order of weight: watch time, click-through rate, session time after the video, topical metadata, and a long tail of small signals. Tags are part of the topical metadata. They help YouTube understand what your video is about when the title and description are ambiguous.

What tags cannotdo is rescue a video the recommender has decided is underperforming. If your click-through rate is low, tagging the video for "trending" will not move it. The honest model: tags are a tidiness check on your metadata, not a growth lever in themselves.

Why we sort specific → broad

YouTube weighs the first few tags more than the rest. Putting your most specific phrases first tells the recommender what the video is actually about, then broader topical tags add context. If you order the other way — broad tags first — you've essentially told YouTube the video is about "cooking" before getting to the part where it's about "making fresh pasta with a $20 hand-crank."

The model we use is told to follow that pattern. You'll notice the top of the list is your exact topic and very close variants. The bottom of the list is the broader category your topic lives in.

The 500-character limit, and what it means in practice

YouTube caps the combined tags field at 500 characters, comma-separated. For a list of 15-20 short phrases that's usually a comfortable fit. If the tool shows you've gone over the limit, drop a few of the broader phrases at the bottom of the list — they're the lowest-value tags anyway.

Tags vs. hashtags in the description

Don't confuse them. The tags field is hidden metadata you fill in under "Show more" in YouTube Studio. Hashtags are inline tokens you write in the description with a # symbol; they show up as clickable links above your video title.

Both work, but they work differently. Tags help YouTube's recommender. Hashtags help viewers who tap them browse other videos with the same tag. A useful pattern: use this tool for the tags field, then take the top 3-5 specific phrases and turn them into hashtags in the description.

Frequently asked questions

Do YouTube tags still matter?+
They matter, but less than people think. YouTube's own documentation says tags help with misspellings of the topic and provide minor topical metadata. Watch time, click-through rate, and audience retention vastly outweigh tags in the ranking signal. Treat tags as a small lever, not a primary growth tactic.
Why specific phrases first?+
YouTube's recommender weights the first few tags more heavily than the rest. Putting your most-specific phrases first — the ones that match the exact video — tells the system "this is what the video is actually about" before the broader topical tags fill in the context.
Is there a tags character limit?+
Yes. The whole tags field maxes out at 500 characters across the comma-separated list. We surface the count in real time so you can see when you are about to cross it.
Should I copy tags from another channel's top video?+
It is tempting, but it does not actually move the needle. Your video either matches the topic or it does not — copying tags will not make YouTube think your video is the same thing. Focus on writing a great hook, a clean thumbnail, and the first 30 seconds.
Is my topic stored?+
No. We pass your topic to the model once, get the tags back, and drop everything from the server. Topics are not logged.
