Research method
Ad testing
See the exact second your ad wins — or loses — attention.
Viewers react to your video and image creative frame by frame. Reaction heatmaps show where interest peaks and drops, so you can cut, reorder and relaunch with confidence.

What it is
Upload an advert and show it to a panel of viewers. They react to it, answer questions and, for video, you see where attention rose and fell.
When to use it
Before you buy media, to choose between versions, or to find what to change.
