To connect GA4 with Google Ads means creating an official link between a Google Analytics 4 property and a Google Ads account so the two platforms can share relevant data. Advertisers do this to view advertising and analytics information together. Once the accounts are linked, Google Ads data can appear in GA4 reports, while eligible GA4 audiences and key events can be used with Google Ads. This article explains the requirements, setup steps, and how to verify the connection.
1. What Does It Mean to Connect GA4 with Google Ads?
1.1 What the Link Does
The link is a permission-based connection between a GA4 property and a Google Ads account. After it is created, the platforms can exchange relevant data, such as advertising data becoming available in GA4 and eligible audiences or key events becoming available for use with Google Ads. The connection brings the two platforms together, but each platform continues to perform its own role. GA4 focuses on analytics and user behavior, while Google Ads focuses on advertising and campaign management.
1.2 Installing GA4 Versus Linking It
Installing GA4 means your website or app sends data to an Analytics property. When you connect GA4 with Google Ads, you connect that Analytics property to your advertising account. These are separate steps. A properly configured GA4 property can collect data without being connected to Google Ads, while the Google Ads link provides additional integration between the two platforms.
1.3 What the Link Does Not Do Automatically
Linking the accounts does not automatically turn every GA4 event into a Google Ads conversion. Conversions, audiences, and other features may require additional configuration after the accounts are linked.
2. What You Need Before You Connect GA4 with Google Ads
Before you begin, make sure you have the following:
- A Google Analytics 4 property that is already collecting data.
- A Google Ads account that you want to link.
- The required access to the GA4 property.
- The required administrative access to the Google Ads account.
- Auto-tagging configured where appropriate, because it helps Google Ads traffic and related campaign information be attributed correctly in GA4.
The person creating the link needs the appropriate permissions in both platforms. If you lack the required access, the Google Ads account you want may not appear during setup. In that situation, an administrator may need to grant access or create the link.
3. How to Connect GA4 with Google Ads
Google updates its interface from time to time, so menu names and positions may differ slightly from those described here.
3.1 Open the GA4 Property
Sign in to Google Analytics with the Google account that has access to the relevant platforms. Select the correct GA4 property and open the Admin area.
If you manage multiple Analytics properties, confirm the property name and ID before continuing. Connecting the wrong property can result in advertising data being associated with the wrong Analytics setup.
3.2 Open Google Ads Links
In the GA4 Admin area, go to:
Admin → Product links → Google Ads links
This is where GA4 lists existing Google Ads connections and allows you to create a new link.
3.3 Select the Google Ads Account
Choose the option to create a new link and select the Google Ads account you want to connect.
You can only select accounts that your Google account is authorized to manage. If you manage several Google Ads accounts, confirm the account name and ID before continuing.
3.4 Review the Linking Settings
The setup process may provide several settings that should be reviewed before completing the connection.
These can include:
- Personalized advertising: Controls whether Analytics data can be used for personalized advertising features in Google Ads.
- Analytics access for Google Ads users: Determines how Analytics data can be made available to users working with the linked Google Ads account.
- Other available settings: Depending on the account and interface, additional linking or data-related options may be shown.
Review these settings carefully before completing the connection. Personalization and privacy controls can affect how data is used, so they should not be changed without understanding their purpose.
3.5 Review and Submit the Link
Review the summary showing the GA4 property and Google Ads account. Confirm that you selected the correct accounts and then submit the link. Once the process is completed, the Google Ads account should appear as linked in the GA4 property.
Google also provides a Google Ads-side route through Data Manager → Connected products, where you can select Google Analytics (GA4) and Firebase and connect an Analytics property.
4. What Happens After You Connect GA4 with Google Ads?
Once the link is active, several capabilities become possible:
- Google Ads data can become available in GA4.
- Relevant GA4 data can become available for use in Google Ads.
- Eligible GA4 audiences can be shared with the linked Google Ads account.
- Relevant GA4 key events can be used in Google Ads conversion measurement.
Some of these capabilities require additional configuration. The account link itself does not automatically configure every conversion, audience, or measurement feature. Data may also take time to appear. If information is not visible immediately after linking, allow sufficient processing time before assuming there is a configuration problem.
5. Using GA4 Key Events with Google Ads
Three terms are important to understand:
- GA4 event: An interaction recorded by Google Analytics, such as a page view, click, or form interaction.
- GA4 key event: An event that has been identified as important to the business.
- Google Ads conversion: An action that Google Ads counts as a conversion through a conversion action configured in the Google Ads account.
Relevant GA4 key events can be used to create Google Ads conversion actions after the accounts are linked. However, linking GA4 with Google Ads does not mean that every Analytics event automatically becomes a Google Ads conversion. Select meaningful actions that represent valuable outcomes rather than importing unnecessary events.
6. Using GA4 Audiences with Google Ads
A GA4 audience is a group of users who share defined characteristics or behaviors based on the data collected by Analytics. When you connect GA4 with Google Ads, eligible audiences from the Analytics property can be shared with the linked Google Ads account. Audience sharing requires the appropriate configuration, and availability depends on eligibility and platform requirements. Audiences may also take time to populate and become available in Google Ads. Using those audiences for specific campaign targeting is a separate topic from connecting the accounts.
7. How Google Ads Data Appears in GA4
The connection also works in the other direction. Google Ads campaign and advertising data can become available in GA4, allowing you to analyze paid traffic alongside how users interact with your website or app. This can help connect advertising activity with subsequent user behavior in Analytics.
Consistent campaign and tracking information is important. If tracking is inconsistent or auto-tagging is not configured appropriately, Google Ads traffic may not be attributed as expected in GA4. This section is about making advertising data available for analysis rather than optimizing Google Ads campaigns.
8. How to Check Whether GA4 and Google Ads Are Connected Correctly
Verification has two parts: checking whether the accounts are linked and checking whether the specific features you need are working.
8.1 Check Whether the Accounts Are Linked
In GA4, go to:
Admin → Product links → Google Ads links
Confirm that the intended Google Ads account is listed as linked.
You can also check the connected product from the Google Ads side through its Data Manager area.
8.2 Check Whether Specific Features Are Working
A visible account link does not necessarily prove that every feature is working correctly.
After allowing sufficient processing time, check whether:
- Google Ads data appears in GA4.
- Relevant conversion actions are available in Google Ads.
- Shared GA4 audiences become available in Google Ads.
If the account is linked but a particular feature is unavailable, investigate that feature’s individual configuration rather than recreating the account link.
9. Common Problems When You Connect GA4 with Google Ads
9.1 Google Ads Account Does Not Appear
Possible causes include:
- You are signed in with the wrong Google account.
- You do not have sufficient permissions.
- You selected the wrong GA4 property.
- You are looking for the wrong Google Ads account.
Check the account access and confirm that you are working with the intended GA4 property and Google Ads account.
9.2 Google Ads Data Is Not Appearing in GA4
Check that:
- The account link is active.
- Campaign tracking and auto-tagging are configured appropriately.
- Enough time has passed for data processing.
- The correct GA4 property and Google Ads account are connected.
9.3 GA4 Key Events Are Not Available for Google Ads
Check that:
- The relevant event is correctly configured as a key event.
- The correct GA4 property is linked.
- The Google Ads conversion setup has been configured appropriately.
The account connection itself does not guarantee that every Analytics key event will automatically appear as a Google Ads conversion.
9.4 GA4 Audiences Are Not Available in Google Ads
Check:
- The audience configuration.
- Audience-sharing settings.
- Eligibility requirements.
- Whether enough time has passed for the audience to become available.
10. What Connecting GA4 with Google Ads Does Not Do
Connecting the accounts is an important integration step, but it has limits. It does not:
- Automatically fix GA4 event tracking.
- Automatically turn every GA4 event into a Google Ads conversion.
- Guarantee that all Analytics data or features will immediately be available in Google Ads.
Additional configuration may be required depending on whether you want to use conversions, audiences, or other Analytics data with Google Ads.
11. Best Practices After You Connect GA4 with Google Ads
After completing the connection:
- Use the correct GA4 property and Google Ads account.
- Keep GA4 events and key events properly organized.
- Use meaningful conversion actions.
- Review audience-sharing settings.
- Check that advertising data is appearing as expected.
- Verify the connection after major account or measurement changes.
- Avoid unnecessary or duplicate configurations.
The goal is not simply to create a link but to make sure the connection supports the specific measurement and analytics requirements of your Google Ads setup.
12. Conclusion
To connect GA4 with Google Ads is to create a permission-based link that allows the two platforms to share relevant data. This can make Google Ads information available in GA4 and allow eligible GA4 audiences and key events to work with Google Ads after the appropriate configuration.
Correct permissions and careful account selection are essential during setup. Remember that linking the accounts is separate from configuring conversions or sharing audiences. After completing the connection, verify the link and confirm that the specific data or features you need are working once processing is complete.
