What is Youtube tag checker?
Tag Relevance Scorer — Grade your video tags with this YouTube tag checker — a transparent 0-100 rubric scores keyword coverage, relevance, and overall tag quality.
A fixed, published rubric scores observable best practices out of 100: keyword coverage — share of title keywords appearing in any tag (40 pts); exact-title tag present (15 pts); multi-word specificity — at least 2 tags of 2–4 words (15 pts); long-tail presence — at least one 4+ word tag (10 pts); budget discipline — total tag-field characters within 400/500 (10 pts); no waste — no duplicates or single-character tags (10 pts). Grades: Strong 80+, Good 60+, Needs work 40+, Weak below 40. Matching is case-insensitive substring matching after lowercasing and trimming — no stemming, no semantic similarity. YouTube publishes no official tag weighting, so this is a heuristic measure of best practices, not a prediction of ranking.

Good to know
- The score is a heuristic — YouTube publishes no official tag weighting, so it measures observable best practices, not ranking impact.
- Matching is case-insensitive substring matching; there is no stemming or semantic understanding (e.g. "bake" will not match "baking" as the same concept is only matched by shared substrings).
- Keyword extraction uses an English stopword list — results are less meaningful for non-English titles.
- Tags identical to title words are marked redundant (strong verdict) but are not penalized heavily — YouTube allows the 500-char field to include them.
- The tool never contacts YouTube; it cannot see your video's actual performance.
How it works
A fixed, published rubric scores observable best practices out of 100: keyword coverage — share of title keywords appearing in any tag (40 pts); exact-title tag present (15 pts); multi-word specificity — at least 2 tags of 2–4 words (15 pts); long-tail presence — at least one 4+ word tag (10 pts); budget discipline — total tag-field characters within 400/500 (10 pts); no waste — no duplicates or single-character tags (10 pts). Grades: Strong 80+, Good 60+, Needs work 40+, Weak below 40. Matching is case-insensitive substring matching after lowercasing and trimming — no stemming, no semantic similarity. YouTube publishes no official tag weighting, so this is a heuristic measure of best practices, not a prediction of ranking.
Examples
Scores 80+ (Strong): full keyword coverage, exact-title tag, multi-word and long-tail tags present.
Scores below 40 (Weak): no title keywords covered; every tag gets a weak verdict.
