Thumbnail A/B Testing

Your thumbnail is the single biggest factor in whether someone clicks your video. But without testing, you're guessing. Our system lets you upload 2-4 thumbnail variants per video, automatically rotates them over 48-72 hours, measures click-through rate for each, and selects the winner. It also uses AI to analyze what makes high-CTR thumbnails work — color contrast, face expressions, text placement — and gives you a score before you even publish. Top creators who A/B test thumbnails consistently see 20-40% higher CTR.
