CAC Report
Blended customer acquisition cost — total ad spend / all unique new customers acquired in the window (regardless of attribution). Per-product CAC uses Shopify line-item detection against your Products settings.
How this is calculated: Ad spend is pulled live from Meta for the selected window (loading…). New customers and revenue come from your synced Shopify orders — an order counts as a new customer only when Shopify’s own customer record says it was that customer’s first ever order, so someone who first bought before your synced history began is a returning customer here, as in Shopify admin. Per-product rows match order line items against the SKUs, names and aliases from Settings → Products.
