Measurement has been digital marketing's biggest challenge since iOS 14.5 and the cookie deprecation timeline began. In September 2025, Google's Enhanced Conversions — both for web and leads — has emerged as the most reliable solution, recovering 20-35% of conversions that would otherwise be lost to privacy restrictions. For MENA advertisers, implementing Enhanced Conversions is now non-negotiable for accurate performance measurement.
How Enhanced Conversions Works
Enhanced Conversions uses first-party customer data (email, phone, name) collected during conversions and hashes it before sending to Google. Google then matches this hashed data against signed-in Google accounts to attribute conversions that would be lost due to cookie restrictions or cross-device behavior.
The process is privacy-safe — only hashed data is transmitted, and users can opt out at any time. Google does not receive or store raw customer information.
Enhanced Conversions for Web
EC for Web enhances your existing conversion tracking tags. When a customer completes a conversion on your website, the tag captures hashed first-party data and sends it alongside the conversion event. This improves measurement accuracy for:
- Cross-device conversions (customer clicks on mobile, converts on desktop)
- Browser-restricted conversions (Safari, Firefox, and soon Chrome)
- Privacy-conscious users who have declined cookies
Enhanced Conversions for Leads
EC for Leads is specifically designed for lead generation businesses. It connects offline lead data (from CRM systems) to online ad interactions. For our healthcare and real estate clients in KSA, this has been transformative — we can now attribute phone calls, walk-in visits, and CRM-qualified leads back to the Google Ads that generated them.

- Implement Google Tag Manager with consent mode enabled
