This report breaks your total attributed revenue down by channel — Organic Search, Paid Search, Organic Social, Paid Social, Email, Referral and Direct.
For each channel, you'll see leads, customers, new revenue, repeat revenue, total revenue, average LTV, spend (if entered), ROI and ROAS.
Channels with no spend entered (like Direct or Referral) show revenue figures without ROI, since there's no cost to measure a return against.
