A thumbnail heatmap (saliency map) estimates where human attention is likely to land first. If the hot zone is a random logo or busy background, your packaging is leaking intent.
ThumbnailTools includes heatmap-style analysis so you can reposition faces, crop tighter, and remove competing elements before publish.
How to act on a heatmap
Move the subject into the hottest region or redesign so the hottest region becomes the subject. Reduce competing bright spots. Enlarge faces. Drop decorative noise.
Limits
Saliency is not a promise of clicks — it is a legibility and hierarchy tool. Combine with CTR testing for decisions that move revenue.
