Paste your title or description to pull out keyword-shaped tags, track them against YouTube’s 500-character tag budget, and see which phrases are worth using as visible hashtags.
YouTube’s own guidance is that tags play a minimal role in discovery, and that they are most useful when your content’s subject is commonly misspelled. That is a narrow claim worth taking literally in both directions: tags are not a ranking lever, and they are not decorative either. Beyond misspellings there is a second real use — disambiguation. If your video is about "Swift" the programming language, the tag field is a cheap place to establish you do not mean the singer.
YouTube’s tag field caps at 500 characters in total, not per tag. Long-tail tags consume it fast, and anything past the limit is dropped silently — which means the tags you cared about most may not be registering. This tool tracks the running total so you can see where the cut falls.
These are different systems. Tags are a hidden metadata field — use ten to fifteen. Hashtags are public: the first three from your description appear above the video title as clickable links, and hashtags in titles are live too. Use two or three relevant hashtags; fifteen in a description is worse than three, because YouTube ignores the overflow and it reads as spam to a human.
Tagging a competitor’s channel name or an unrelated trending topic to piggyback on their traffic breaches YouTube’s metadata policy. It is also ineffective — tags are far too weak a signal to hijack anyone’s audience.

YouTube states they play a small role in discovery and are most useful when your subject is commonly misspelled, or when a keyword needs disambiguating. They are worth filling in properly but are not a ranking lever.
500 characters in total across all tags, not per tag. Long-tail tags consume it quickly and anything beyond the limit is dropped silently.
Around ten to fifteen relevant tags. Stuffing dozens provides no benefit, and tags unrelated to your content breach YouTube’s metadata policy.
Tags are a hidden metadata field — use ten to fifteen. Hashtags are public: the first three from your description appear above the video title as clickable links. Use two or three.
Around sixty characters or fewer. Titles truncate in browse and suggested surfaces, so anything essential beyond that may not be visible.
No. Tagging unrelated channels or trending topics breaches YouTube’s metadata policy, and tags are too weak a signal for it to work regardless.
