Score a title across 7 evidence-correlated dimensions and get 3 A/B variation suggestions. Updates live as you type. Heuristic only; no calculator can predict CTR, but the dimensions that move it are well-documented.
Variants apply proven title patterns (question, list, contrast, time-bound). Use TubeBuddy or vidIQ to split-test 2 to 3 of these against your original.
YouTube's native A/B testing covers 3 thumbnails per video. TubeBuddy and vidIQ extend this with multi-variant title and tag testing, impressions tracking, and competitor benchmarks.
Seven dimensions weighted 8 to 18 points each, summed to 0-100. Length and SERP truncation use Google and YouTube SERP measurements (mobile feed truncates around 60 chars, desktop around 70). Curiosity, emotion, and pattern dimensions track signal categories observed in TubeBuddy and vidIQ creator-aggregate datasets and in the Yang Creator Economy Report 2024. Keyword fit checks for the primary keyword inside the first 50 chars. Score bands: 80+ top decile, 60-79 above median, 40-59 median, below 40 below median. This is a heuristic, not a prediction.
