How to Link Google Analytics 4 to Your Google Ad Grant Account

Linking GA4 to your Google Ads Grant account is one of the most important setup steps you'll do, yet it only takes about 5 minutes. Without this link, your Grant account can't import conversions from GA4, Smart Bidding can't access your analytics data, and you lose visibility into what happens after someone clicks your ad.

This is the quick-reference version. For the complete GA4 installation and conversion tracking setup, see our full GA4 setup guide.

Key Takeaways - Linking takes about 5 minutes and needs to be done from both GA4 and Google Ads - You need admin access to both accounts (ideally the same Google account for both) - Auto-tagging must be enabled in Google Ads for the link to work properly - Once linked, you can import GA4 events as Google Ads conversions

Prerequisites

Before linking, confirm:

1. You have a GA4 property set up with a web data stream for your website. If not, follow our GA4 setup guide first.
2. You have admin access to both the GA4 property and the Google Ads Grant account. Using the same Google account for both is simplest.
3. GA4 is installed on your website and receiving data (check Realtime report).

Step 1: Enable Auto-Tagging in Google Ads

Auto-tagging appends a unique click identifier (GCLID) to your ad URLs, which lets GA4 attribute website visits back to specific ad clicks.

1. In Google Ads, click Admin (gear icon)
2. Click Account settings
3. Find Auto-tagging
4. Ensure "Tag the URL that people click through from my ad" is checked
5. Click Save if you made changes

This is usually enabled by default, but verify it.

Step 2: Create the Link in GA4

1. Go to analytics.google.com
2. Select your property
3. Click Admin (gear icon, bottom left)
4. Under your property, click Product links
5. Click Google Ads links
6. Click Link
7. Click Choose Google Ads accounts
8. Select your Grant account from the list (it appears by Customer ID)
9. Click Confirm
10. Enable Personalized advertising (allows audience sharing between platforms)
11. Click Next, then Submit

Step 3: Verify the Link in Google Ads

1. In Google Ads, go to Tools and settings
2. Click Linked accounts
3. Find Google Analytics (GA4) and click Details
4. Your GA4 property should show as "Linked"

If it shows as "Not linked," the link may be pending approval from the other platform. Check GA4 for any pending link requests.

Step 4: Verify Data Is Flowing

After linking, verify that data moves correctly between the two platforms:

In GA4: Go to Reports, then Acquisition, then Traffic acquisition. After your ads start running, you should see a source/medium of "google / cpc" representing your Grant ad traffic.

In Google Ads: After 24-48 hours, go to Goals, then Conversions. If you've set up key events in GA4, you can now import them as Google Ads conversions (see our conversion tracking compliance guide for the import process).

What Linking Enables

Troubleshooting

"I don't see my Google Ads account in GA4's linking options." You need admin access to both accounts. If they're under different Google accounts, you'll need to add the GA4 admin's email as a user on the Google Ads account (or vice versa).

"The link shows as 'Pending.'" The admin of the other platform needs to approve the link. Check both GA4 and Google Ads for pending link requests.

"Auto-tagging is on but GA4 shows all traffic as 'direct.'" The GA4 tag may not be installed correctly on your website. Verify using GA4's Realtime report while browsing your site. Also check that no other redirects or URL parameters are stripping the GCLID.

"I linked GA4 but don't see conversions in Google Ads." Linking alone doesn't import conversions. You still need to mark events as key events in GA4, then explicitly import them in Google Ads (Goals, then Conversions, then Import). See our full GA4 guide for the complete process.

Frequently Asked Questions

Can I link multiple GA4 properties to one Google Ads account? Yes, but most nonprofits only need one GA4 property linked. Multiple links are useful if you have separate websites with separate GA4 properties.

Do I need to re-link if I create a new GA4 property? Yes. Each GA4 property is linked independently. If you create a new property, you need to create a new link.

Does this work the same for nonprofits globally? Yes. The GA4-to-Google Ads linking process is identical worldwide.

Key Takeaways

• Linking takes 5 minutes and is done from both GA4 and Google Ads
• Enable auto-tagging first so GA4 can attribute clicks to your ads
• Same Google account for both is the easiest setup
• Linking enables conversion import, Smart Bidding optimization, and cross-platform reporting
• Linking alone doesn't import conversions: you still need to mark events and import them
• Verify data flow by checking for "google / cpc" traffic in GA4 after ads start running
