Problem
We run an online vehicle auction marketplace and want to surface our most engaged shoppers from 2026. Treating every ad impression and every site search a person made that year as one touchpoint, total the touchpoints per user across both sources, most active first.
Summary
A bid, a click, a search: each one is a vote. Total them honestly.
