GA4 and ad conversion tracking: one clean setup template
Reduce reporting gaps by defining consistent conversions across GA4, Google Ads and Meta.

Define the business event first
“Conversion” means different things to each team. Separate purchase, qualified form, appointment and WhatsApp click. Do not promote micro events like page views to primary conversions.
Mark key events in GA4 and import into Google Ads only the events you bid on. Importing everything pollutes bidding.
Enhanced conversions and server-side
Enable enhanced conversions and server-side tagging when you can. They harden matching under cookie limits. Keep test traffic in a separate property or filter.
The same purchase can differ across GA4, Ads and Meta — models differ. Anchor decisions on one source of truth and treat the others as directional.
Weekly discrepancy checks
Compare CRM sales with ad-panel conversions weekly. If the gap exceeds about 20 percent, inspect tags, attribution and spam forms.
Tecrube’s setup wizard maps GA4–Ads–Meta events, lists missing key events and suggests spam-lead filters.
