How do I connect Google Ads to GA4?

Open the analytics property, go to the product linking area, and connect the correct ad account. Then make sure auto-tagging is enabled in the ad account and that your key GA4 events are marked as conversions. After that, test a live click and confirm the campaign data appears in analytics.

Why do Google Ads and GA4 numbers not match?

They measure different things and often use different attribution logic. One system may count by click date while the other counts by conversion date. Consent loss, cross-device behavior, and duplicate events can widen the gap further.

Should I import GA4 conversions into Google Ads?

Usually yes, if the GA4 event represents a real business outcome and the event is clean. Don't import noisy events or duplicate actions, since that can train bidding in the wrong direction.

Which platform is more accurate, Google Ads or GA4?

Neither is universally more accurate. The ad account is better for auction-side metrics, while GA4 is better for post-click behavior and site context. For final business truth, use CRM or backend data.

Why does GA4 show fewer conversions than the ad account?

Consent restrictions, cookie loss, and event firing issues can reduce observed analytics conversions, and the ad account may attribute or date a conversion differently.
