YouTube Thumbnail CTR & Safe Zone Simulator
Test your existing thumbnails or design new ones. Detect bottom-right timestamp badge obstructions, evaluate mobile text legibility, and preview your artwork inside a live YouTube dark-mode feed.
The YouTube Timestamp Problem: Why 15% of Your Thumbnail is Invisible
Every video rendered across the YouTube ecosystem features a mandatory timestamp pill (e.g., "10:45" or "1:02:18"). On desktop web browsers, this badge is relatively discreet. However, on the YouTube mobile app (which accounts for over 70% of total video watch time), the badge scales up significantly and includes a translucent drop shadow.
If you place your primary emotional punchline, face cutout, or branding logo in this 140×60 pixel buffer, prospective viewers cannot read your message while scanning their feed. This single error often degrades click-through rates by 2.5% to 4.8%.
Understanding the Visual Saliency Heatmap
Human visual cognition does not inspect a thumbnail sequentially from top-to-bottom. The visual cortex is drawn to high-contrast focal islands in a distinct sequence:
- Fixation 1 (Primary High-Luminance Anchor): Eyes immediately lock onto bright human faces or neon yellow/cyan typography.
- Fixation 2 (Action Indicator / Directional Vector): Eyes follow directional cues such as pointing arrows or gaze vectors from the subject.
- Fixation 3 (Secondary Context Badge): Finally, viewers register context badges (e.g., "100% REAL", "NEW TECH") before deciding to click.
Our built-in Saliency Heatmap simulates this eye-tracking fixation pattern so you can ensure your visual hierarchy leads the viewer directly to your curiosity hook.
