How to Track ROAS & Conversions in Google Ads (2026 Guide)
Without trustworthy purchase conversion values, Smart Bidding optimizes toward noise. Misconfigured eCommerce tracking is still one of the most common failure modes.
Step 1: Purchase conversion with revenue
Option A: Google Ads tag on the order confirmation page with dynamic order value.
Option B: Import GA4 purchase events. Many teams use the Ads tag as the primary optimization action and GA4 as secondary for journey insight.
Enhanced conversions
Hashed first-party data improves modeled conversions when cookies are blocked or users switch devices. Typical reporting lift on the order of 10–25% cited in industry guidance — and cleaner signals for bidding.
ROAS calculation
ROAS = revenue attributed to ads / ad spend. Example: $10,000 revenue / $2,500 spend = 4x.
Caveat: In-platform ROAS can exceed business ROAS when attribution double-counts touchpoints. Reconcile to Shopify/Woo/your BI.
Attribution
Default is usually data-driven attribution (DDA). Confirm in conversion settings; use GA4 and platform analytics for profitability truth.
