When rage clicks mean a broken size guide
Dense click clusters on inactive size chips often signal stock logic problems — not shopper confusion about fashion.
Rage-click clusters look dramatic on a heat map. On product pages they often sit on size chips that appear selectable but return no stock state.
Separate intent from interface failure
If attention maps show shoppers reaching the size row and click maps show repeated taps on a single chip, we check whether the chip is disabled, overlaid, or waiting on a slow stock call. That diagnosis belongs in the annotation, not a vague note about “engagement.”
Pair with session clues when available
When clients can share a handful of session recordings for the same URLs, we sample clips that match the rage-click coordinates. Recordings are supporting evidence; the heat map remains the primary artefact in our reports.
Recommendation style
We list the friction as a hypothesis with a suggested owner — usually front-end or inventory messaging — and stop short of prescribing code. The goal of heat-map insight reporting is a clearer decision, not a pseudo-ticket backlog.
