How to Link GA4 to Google Ads: Conversions, Audiences & Why It Matters

What linking unlocks, how to set it up with the right access, and the double-counting and consent traps that quietly corrupt your data.

VDBy Vikas Disale·7 min read
Quick answer

Linking GA4 to Google Ads lets each use the other’s data: you can import GA4’s event-based conversions and behavioural audiences into Google Ads, and see ad performance inside GA4. Set it up in GA4 Admin → Product links → Google Ads, with auto-tagging on. The big trap is double-counting — don’t track the same action with both GA4 and the Ads tag, or you’ll mislead bidding.

📢
2026 updateFrom 15 June 2026, the ad_storage consent signal becomes the single control governing the ad data shared between GA4 and Google Ads — the old Google Signals setting no longer governs it. If you rely on GA4 to feed Ads, confirm your consent setup explicitly controls ad_storage.
1Why link them

Two tools, one picture of the customer

Google Ads sees clicks and conversions; GA4 sees what people do on your site. Linking them lets each use the other’s data — you can pull GA4’s richer, event-based conversions and behavioural audiences straight into Google Ads, and see your ad performance inside GA4.

3How to link

A few minutes, with the right access

  • Get access: Editor on the GA4 property and admin on the Google Ads account.
  • Create the link in GA4 Admin → Product links → Google Ads (or from the Ads side under linked accounts).
  • Turn on auto-tagging so GA4 can attribute sessions to ad clicks.
  • Import what you need — key events as conversions, and audiences for remarketing.
⚠️
The double-counting trapDon’t import a GA4 conversion and track the same action with the Google Ads tag — you’ll count it twice and mislead bidding. Pick one source per action.
Key takeaways
  1. Linking lets GA4 and Google Ads share conversions, audiences and reporting.
  2. Import GA4 key events as conversions and GA4 audiences for remarketing.
  3. Link in GA4 Admin → Product links → Google Ads, with auto-tagging on.
  4. Never track the same action with both GA4 and the Ads tag — it double-counts.
  5. From 15 June 2026, ad_storage consent governs the ad data shared between them.

GA4 linking FAQs

How do I link GA4 to Google Ads?
In GA4, go to Admin, then Product links, then Google Ads, and create the link. You need Editor access on the GA4 property and admin on the Google Ads account, with auto-tagging turned on.
What does linking GA4 and Google Ads do?
It lets you import GA4 conversions and audiences into Google Ads, and see your ad performance inside GA4, giving you a fuller picture of the customer journey.
Should I use GA4 conversions or Google Ads conversions?
Use one source per action. Tracking the same conversion with both GA4 and the Google Ads tag double-counts it and misleads bidding, so choose whichever is more reliable for each action.

Yes. Once linked, you can import GA4 audiences built on on-site behaviour, such as people who viewed pricing or abandoned a cart, and use them for remarketing.
