September 2025 made Enhanced Conversions (EC) non-negotiable for serious advertisers. EC uses hashed first-party data (email, phone) to match website conversions with Google-signed-in users, recovering conversions that cookies missed.
For a fashion e-commerce client, EC recovered 27% of purchases that were previously unattributed — directly impacting budget allocation decisions. Without EC, we were under-investing in top-of-funnel campaigns because we could not see their true contribution.
Implementation required technical updates: modifying website conversion tracking to capture and hash user data, ensuring GDPR/privacy compliance, and validating the setup through Google Ads diagnostics.
The performance impact was measurable within 14 days. ROAS reporting improved by 15-25% for most clients because the attribution gap closed.
We also integrated Enhanced Conversions for Leads, which matched offline conversions (phone calls, in-store visits) with ad interactions. For a healthcare client, this revealed that 40% of phone appointment bookings originated from Display ads we were considering cutting.
