  • Flag any rows where variance exceeds ±30%
  • Recommend which model better matches buyer behavior, based on median journey length and number of touches

What This Prompt Does

This prompt attributes 100 percent of Closed‑Won revenue from the past 180 days to both a First‑Touch model and a Last‑Touch model, then aggregates results by channel and the top 20 campaigns. It generates a variance report showing First‑Touch dollars, Last‑Touch dollars and percentage variance for each row. Any channel or campaign with variance exceeding ±30 percent is flagged and accompanied by commentary suggesting which model better represents the buyer journey, based on median journey length and touch count.
