About this tool
Group keyword sets once and reuse them across a channel, with de-duplication and a live count against the 500-character tag limit.
Video Tag Keyword Organizer keeps a channel's keywords in named groups — core, topic, long tail, brand — and builds a per-video tag set from the groups you tick. It removes case-insensitive duplicates, counts characters exactly the way the tags field does (every tag plus the commas between them) and shows which tags will not fit inside the 500-character limit rather than truncating them silently. Aimed at creators and channel managers who reuse the same keyword blocks across dozens of uploads.

Characters include the separating commas, so the number you see is the number the field will accept.
Tags that do not fit are listed separately so you can decide what to cut.
Define a keyword block once and apply it to every video in the series.
The tags field accepts 500 characters in total, and the commas separating the tags count towards that. That works out to roughly 25 to 35 tags of average length, so the budget runs out faster than most people expect once long-tail phrases are added.
There is no magic number; what matters is that the tags fit inside the 500-character budget and describe the video accurately. A practical set is 10 to 20 tags: a few broad terms, the exact phrase from your title, two or three long-tail variants and any common misspellings.
They are a minor signal. YouTube has said tags play a limited role because the title, description, thumbnail and viewer behaviour carry far more weight — tags mainly help with spellings and phrasings the title cannot include. Do not spend an hour on tags and ten minutes on the title.
Reusing a small core block is fine and keeps a channel's topic consistent, but every video should also carry tags specific to its own subject. If two videos share nearly all their tags, neither is telling the platform what makes it different.
