Demand left behind, by product and worry

Biggest leak: Driftwood 2P Tent. About 32% of shoppers who left it were worried about delivery.

Each row is a product; each cell is demand from shoppers who left it with that worry. Darker means more. A shopper Qualm rates 70% fit and 30% value counts 0.7 and 0.3, so these are estimates, not counted answers. Click a cell to see why.

What to fix first

Ranked by demand left behind. The last column is a what-if: it assumes 4%–15% of those shoppers would buy once their worry is answered. That's a guess to test, not a forecast.

What your exit survey misses

The survey pop-up only appears on desktop, and phone shoppers worry more about delivery. So the survey under-counts delivery worries by 5.1 points. Qualm, which scores every visit, is 0.4 points off.
