Attribution note: Channel mix uses Shopify's first-visit source; Meta-attributed orders are matched by UTM. Meta's purchase attribution windows differ from Shopify's, so reported numbers can vary. The "Blended ROAS" KPI divides total Shopify revenue (all channels) by total Meta spend; per-ad ROAS is what Meta reports. Deltas next to KPIs compare to the prior month — except YTD 2026, which shows totals only.
