These metrics come from sales recorded by your UTM Integrations (webhooks from sales platforms connected to Ads Editor), counting only sales approved in the report period. UTM Purchases is the number of tracked sales, UTM Revenue is the net value of those sales (after the platform fee) and Profit is UTM revenue minus ad spend. Because sales are linked by ad account, the amounts are distributed across campaigns in proportion to each one's spend. So they are an approximation per campaign and exact for the account total. If these metrics show zero, check that the report's ad account is linked to a project with a webhook set up on the Integrations page.
