YouTube's native A/B testing covers 3 thumbnails per video. TubeBuddy and vidIQ extend this with multi-variant testing + impressions-tracking + competitor benchmarks.
Each of 8 design dimensions scores 0-15 based on correlation strength with above-average CTR observed in TubeBuddy + vidIQ aggregate creator datasets, MrBeast/Veritasium creator interviews, and the Yang Creator Economy Report 2024. Total 0-100. Estimated CTR range applies a niche-agnostic mapping: 80+ score correlates with 8-14% CTR (top decile), 60-79 with 5-9% (above median), 40-59 with 3-6% (median), below 40 with 1-4% (below median). Real CTR depends on niche, audience relationship, title pairing, and impressions context. This is a heuristic, not a prediction.
