Without accurate conversion tracking, ad platforms optimise blindly and you cannot tell which campaigns make money. A solid setup records the actions that matter, sends them to GA4, Google Ads and Meta, and respects privacy consent. Here is a practical approach for lead generation and eCommerce websites.
1Decide What to Track
- Primary: form submissions, purchases, booked calls
- Secondary: phone clicks, WhatsApp clicks, email clicks
- Offline: qualified leads and closed sales from your CRM
2Use Google Tag Manager
Tag Manager centralises your tracking. Create triggers for thank-you pages, form submissions and click events, and send events to GA4, Google Ads and Meta from one place.
3Add Server-Side Signals
Meta’s Conversions API and Google’s enhanced conversions send hashed first-party data to improve match rates and resilience against browser restrictions. Use them alongside browser tags.
4Import Offline Conversions
Sending qualified lead and sale data back to Google Ads and Meta lets their algorithms optimise for real business outcomes, not just form fills.
5Respect Consent and Test
Implement consent banners and Consent Mode where required. Test every conversion with preview tools before launch, and audit monthly.
