Joining sentiment scores to a shipping-calculator drop

A shipping calculator often reveals costs shoppers did not expect. Reviews written days later may mention “postage” or “courier” even when the abandonment happened at that calculator. Joining the two needs shared dates and honest language about association.

Align the windows

Export reviews with timestamps. Export the calculator interaction events for the same catalogue and period. We do not claim a review “caused” an abandon; we show whether cold postage themes thicken in the same weeks the calculator step softens.

Read the verbatims aloud

Before drawing the poster, we read a sample of postage-theme lines in the client’s own words. If the language is about damaged parcels rather than price surprise, the conversion join points to a different operational owner.

Chart one claim

The poster shows postage-theme polarity beside the calculator completion rate across weeks. A second page lists candidate actions — copy, threshold messaging, or carrier choice — without ranking them as guaranteed lifts.
