Type a topic above and we'll generate a pool of YouTube tags optimised to fit YouTube's 500-character limit.
How YouTube tags work
YouTube tags are descriptive keywords you add in YouTube Studio (Details → Show more → Tags) that help YouTube understand your video's topic. The official limit is 500 characters total (including commas).
Use a mix of: (1) exact-match tags (your main topic), (2) long-tail tags (specific phrases people actually search), (3) related tags (adjacent topics), and (4) niche-coded tags (your category language). Avoid stuffing with unrelated trending terms — YouTube penalises tag spam.
Tags are one ranking factor among many; title, description, thumbnail, and watch-through rate matter more. Don't expect tags alone to rank a weak video.

Frequently asked questions
How many YouTube tags should I use?
YouTube allows up to 500 characters total in the tags field (including commas). For most videos, 12-20 tags is the sweet spot. Our generator auto-fits as many tags as possible under the 500-character cap and surfaces a count so you know you're at the limit.
Do YouTube tags still help with ranking in 2026?
Tags are a minor ranking signal compared to title, description, thumbnail, and watch-through rate. They help YouTube understand context when your video has limited engagement signals (new uploads, niche topics). Don't over-invest in tag optimisation; do invest in a strong first 30 seconds and a click-worthy thumbnail.
What's the YouTube tag character limit?
500 characters total across all tags combined, including the commas that separate them. Individual tags can be longer but YouTube prioritises the first 30 characters of each. Our generator counts characters live and shows how many tags fit the limit.
How do I add tags to my YouTube video?
In YouTube Studio: open the video → Details → scroll to Show more → Tags field. Paste your comma-separated tags. Save and publish (or republish). Changes affect ranking gradually over the next 24-72 hours as YouTube re-indexes the video.
Are tag generators against YouTube's rules?
No. YouTube prohibits 'tag stuffing' (unrelated trending terms used to manipulate discovery), but topic-relevant tags generated by tools are explicitly fine. Our generator produces tags from your topic + niche only — we don't inject unrelated trending terms.
What about the rest of my YouTube optimisation?
Pair your tags with a strong title (use our free YouTube title generator), a full SEO description (use the description generator), and the right channel branding (use the channel name generator). All four are browser-based, no signup.
