Why You Need to Connect GA4 with Google Ads
When you connect GA4 with Google Ads, you unlock a wealth of capabilities that transform how you measure and optimise your advertising campaigns. This integration allows data to flow seamlessly between both platforms, giving you a complete picture of your customer journey from initial ad click through to final conversion.
The primary benefits of linking these two powerful platforms include:
- Access to GA4’s more sophisticated conversion tracking and attribution models within Google Ads
- The ability to create remarketing audiences based on detailed behaviour tracked in GA4
- Enhanced reporting that combines advertising data with website engagement metrics
- Automatic tagging of Google Ads campaigns for accurate traffic source tracking
- Improved campaign optimisation through Smart Bidding strategies powered by GA4 conversion data
- Cross-platform insights that reveal how users interact with your site after clicking ads
Without this connection, you’re working with fragmented data that doesn’t tell the complete story of your advertising performance. The ga4 google ads integration bridges this gap and provides the foundation for data-driven marketing decisions.
Prerequisites and Requirements
Before you begin the process to link google analytics with google ads, ensure you have the necessary access permissions and account setup completed:
| Requirement | Minimum Level | Purpose |
|---|---|---|
| Google Analytics 4 Property | Editor or Administrator | To create the link and modify property settings |
| Google Ads Account | Administrative access | To accept the link request and import conversions |
| Google Account | Access to both platforms | To authenticate and authorise the connection |
| GA4 Data Collection | Active and verified | To ensure data is flowing before linking |
Important: If you don’t have the required permissions, contact your organisation’s Google Analytics or Google Ads administrator. The linking process requires elevated access on both platforms and cannot be completed with viewer or analyst-level permissions.
Additionally, ensure your GA4 property is properly collecting data from your website. If you’ve recently set up GA4, wait at least 24 hours to allow data to populate before attempting the connection. If you need assistance with GA4 implementation, consider reviewing GTM setup service for professional configuration support.
How to Connect GA4 to Google Ads Step-by-Step
The process to connect ga4 google ads is straightforward when you follow these detailed steps. The linking is initiated from Google Analytics 4 and then confirmed in Google Ads.
Access Google Analytics Admin Settings
Sign in to your Google Analytics account and navigate to the property you want to link. Click on the Admin gear icon in the bottom left corner of the interface. In the Property column, locate and click on Google Ads Links.
Initiate the Link Creation
Click the Link button (usually blue) to begin the linking process. You’ll see a list of Google Ads accounts that are accessible with your current Google Account credentials. If you don’t see your Google Ads account listed, ensure you’re signed in with the correct Google Account that has access to both platforms.
Select Your Google Ads Account
From the list of available accounts, check the box next to the Google Ads account(s) you want to link. You can link multiple Google Ads accounts to a single GA4 property if needed. Click Confirm to proceed to the configuration settings.
Configure Link Settings
On the link configuration screen, you’ll need to enable several important options:
- Personalised advertising: Enable this to use GA4 audiences for remarketing in Google Ads
- Auto-tagging: Turn this on to automatically tag your Google Ads URLs for accurate tracking
These settings are crucial for the full functionality of your integration. Review each option carefully before proceeding.
Submit the Link Request
After configuring your settings, click Submit. The link will be created immediately, and if you have administrative access to the Google Ads account, it will be active straight away. If someone else manages the Google Ads account, they’ll need to approve the link request.
Pro Tip: When you link google analytics with google ads, auto-tagging is essential for accurate attribution. This feature appends a unique identifier (GCLID) to your ad URLs, allowing GA4 to precisely track which clicks came from Google Ads campaigns.
Confirm in Google Ads (If Required)
If you’re not an administrator of the Google Ads account, the account admin will receive a notification about the pending link. They should sign in to Google Ads, navigate to Tools & Settings > Setup > Linked accounts, find Google Analytics 4, and approve the connection request.
Once completed, your GA4 property and Google Ads account are successfully connected. However, this is just the first step—you’ll also want to import conversions to maximise the value of this integration.
How to Import GA4 Conversions into Google Ads
After establishing the connection, the next critical step is to import ga4 conversions into google ads. This allows Google Ads to optimise your campaigns based on the more sophisticated conversion tracking available in GA4.
Set Up Events as Conversions in GA4
Before you can import conversions, you must first mark events as conversions in GA4. Navigate to Admin > Events in your GA4 property. Find the events you want to track as conversions (such as ‘purchase’, ‘generate_lead’, or ‘sign_up’) and toggle the Mark as conversion switch to the on position.
Note: Only events that are already being collected in GA4 can be marked as conversions. If you don’t see the event you need, you’ll need to set up event tracking first through Google Tag Manager or directly in your GA4 configuration.
Access Google Ads Conversions
Sign in to your Google Ads account and click on Goals in the top menu, then select Conversions from the dropdown. Alternatively, navigate through Tools & Settings > Measurement > Conversions.
Import GA4 Conversions
Click the blue + New conversion action button, then select Import. Choose Google Analytics 4 properties from the list of import sources. You’ll see a list of GA4 conversions available for import from your linked property.
Select Conversions to Import
Check the boxes next to the GA4 conversions you want to import into Google Ads. Consider carefully which conversions are most valuable for your campaign optimisation. Not every GA4 conversion needs to be imported—focus on those that represent genuine business value.
Configure Conversion Settings
After selecting your conversions, configure important settings:
- Goals and Actions: Categorise the conversion appropriately (Purchase, Submit lead form, etc.)
- Value: Decide whether to use the transaction-specific value from GA4 or assign a default value
- Count: Choose between ‘One’ (count only one conversion per click) or ‘Every’ (count all conversions)
- Conversion window: Set how long after an ad interaction conversions should be counted
- Attribution model: Select which attribution model to use (data-driven is recommended when available)
Save and Verify
Click Import and continue, then Done to complete the process. Your imported conversions will appear in your Google Ads conversions list. Note that it may take several hours for conversion data to begin flowing from GA4 to Google Ads.
Important: When you import GA4 conversions into Google Ads, the conversion data is not retroactive. Only conversions that occur after the import will be recorded in Google Ads. Plan your import timing accordingly, especially if you’re launching new campaigns.

Setting Up Audience Sharing Between Platforms
One of the most powerful features of the ga4 google ads integration is the ability to share audiences for remarketing. GA4’s sophisticated audience builder allows you to create highly targeted segments based on user behaviour, which can then be used in Google Ads for remarketing campaigns.
Creating Audiences in GA4
To create audiences that can be shared with Google Ads, navigate to Admin > Audiences in your GA4 property. Click New Audience and either use a suggested audience template or build a custom audience based on specific conditions such as:
- Users who viewed specific pages but didn’t convert
- Users who added items to cart but abandoned the purchase
- High-value customers based on purchase amount or frequency
- Users who engaged with specific content categories
- Users who completed certain events within a specific timeframe
Pro Tip: GA4 audiences need to accumulate at least 100 users before they become available in Google Ads. For Display Network campaigns, audiences need at least 100 active users, and for Search campaigns, they require 1,000 active users over the past 30 days. Plan your audience strategy with these thresholds in mind.
Enabling Audience Sharing
When you create an audience in GA4, ensure the Include users from linked Google Ads accounts option is enabled. This setting was configured during the initial linking process but can be modified at any time in the Google Ads Links section of your GA4 Admin area.
Accessing GA4 Audiences in Google Ads
Once audiences are created and shared, they’ll appear in Google Ads within 24-48 hours. To access them, go to Tools & Settings > Shared library > Audience manager in your Google Ads account. Your GA4 audiences will be listed under Google Analytics sources and can be applied to any Search, Display, Video, or Shopping campaign.
This audience sharing capability transforms your remarketing strategy by leveraging the rich behavioural data captured in GA4 to reach users with precisely targeted messages across Google’s advertising platforms.
Verifying Your GA4 Google Ads Integration
After completing the connection process, it’s essential to verify that data is flowing correctly between platforms. Here’s how to confirm your ga4 google ads integration is working properly:
Check Link Status in GA4
Navigate to Admin > Google Ads Links in your GA4 property. Your connected Google Ads account should show a status of Linked. Click on the link name to view detailed configuration settings and confirm that auto-tagging and personalised advertising are enabled as intended.
Verify in Google Ads
Sign in to Google Ads and go to Tools & Settings > Setup > Linked accounts. Under Google Analytics 4, you should see your GA4 property listed with a status of Linked. Click Details to view which features are enabled.
Test Auto-Tagging
Click on one of your Google Ads in a test environment or incognito browser window. Check the URL in your browser’s address bar—you should see a parameter that begins with “gclid=” appended to your landing page URL. This confirms that auto-tagging is functioning correctly.
Monitor Conversion Data Flow
After importing GA4 conversions, monitor the Conversions section in Google Ads. Within 24-48 hours, you should begin seeing conversion data populate for your imported GA4 conversions. Compare this with your GA4 reports to ensure data consistency.
Data Discrepancies: Small differences between GA4 and Google Ads conversion numbers are normal due to different attribution models, data processing times, and user privacy settings. Significant discrepancies (more than 20%) warrant investigation.
Check Audience Availability
If you’ve created audiences in GA4, verify they’re accessible in Google Ads by checking the Audience manager. Remember that audiences need time to accumulate sufficient users before they meet Google Ads’ minimum thresholds for campaign use.
Best Practices for GA4 and Google Ads Integration
To maximise the value of your connection between GA4 and Google Ads, follow these proven best practices:
Strategic Conversion Selection
Don’t import every GA4 conversion into Google Ads. Focus on conversions that represent genuine business value and that you want campaigns to optimise towards. Too many conversion actions can dilute your campaign optimisation and make performance analysis more complex.
| Conversion Type | Import to Google Ads? | Reasoning |
|---|---|---|
| Purchase / Transaction | ✅ Yes | Direct revenue generation—critical for optimisation |
| Lead Form Submission | ✅ Yes | High-value action that indicates strong intent |
| Phone Call Click | ✅ Yes (for businesses relying on calls) | Important conversion path for service businesses |
| Newsletter Sign-up | ⚠️ Maybe | Depends on your business model and nurture process |
| Page Scroll Depth | ❌ No | Engagement metric, not business outcome |
| Video View | ❌ No | Better tracked as engagement, not conversion |
Maintain Consistent Naming Conventions
Use clear, descriptive names for your conversions and audiences that make sense across both platforms. This consistency simplifies reporting, campaign management, and team collaboration. Include details about the conversion type and source in the name, such as “GA4 – Purchase – Website” or “GA4 Audience – Cart Abandoners – 7 Days”.
Leverage Enhanced Conversions
When you link google analytics with google ads, consider implementing enhanced conversions, which use hashed, first-party customer data to improve conversion measurement accuracy. This is particularly valuable in an era of increasing privacy restrictions and cookie limitations.
Regular Monitoring and Auditing
Schedule monthly reviews of your integration to ensure:
- All links remain active and properly configured
- Conversion data is flowing accurately between platforms
- Audiences are updating and meeting minimum size requirements
- Auto-tagging is functioning correctly on all campaigns
- Attribution models are aligned with your business objectives
Privacy and Compliance Considerations
Ensure your integration complies with data protection regulations such as GDPR and CCPA. When enabling personalised advertising and audience sharing, verify that your privacy policy clearly discloses how visitor data is collected and used across Google’s platforms. Implement proper consent mechanisms where required by law.
Important: When sharing audiences for remarketing, respect user privacy choices. GA4 automatically excludes users who have opted out of personalised advertising, but you should regularly review your data collection and sharing practices to ensure ongoing compliance.
