1. Define the campaign audience
Choose the unique people reached by the merchandise promotion across the selected channels.
2. Enter unique audience reached
Deduplicate people where possible instead of adding overlapping channel audiences.
3. Enter unique buyers
Count each purchaser once even when that person places several orders.
4. Review the conversion rate
The main percentage is the share of reached people who became buyers.
5. Use the supporting ratios
Buyers per 1,000 and one-in-X audience ratios make campaign comparison easier.
