How to Link GA4 to Google Ads

Linking Google Analytics 4 (GA4) to Google Ads is essential for tracking ad performance, gaining insights into user behavior, and optimizing ad campaigns. By connecting GA4 to Google Ads, you can see how your ads drive user engagement, measure conversions, and refine targeting strategies.

Step 1: Ensure Permissions #

To link GA4 to Google Ads, make sure you have the following permissions:

  1. GA4 Account: You need “Editor” permissions on your GA4 property.
  2. Google Ads Account: You need “Admin” access to the Google Ads account you want to link.

Step 2: Navigate to GA4 Admin Settings #

  1. In GA4, go to Admin at the bottom left of the page.
  2. Under the Property column, find and select Google Ads Links.
  1. Click Link in the Google Ads Links page.
  2. Choose Select Google Ads Accounts, and you’ll see a list of Google Ads accounts for which you have access.
  3. Select the Google Ads account you want to link.
  4. Click Confirm and then Next to proceed.

After selecting the account, you’ll have a few configuration options:

  • Enable Personalized Advertising: This allows GA4 to use audiences for remarketing, a powerful feature for re-engaging users based on specific behaviors.
  • Enable Auto-Tagging: Ensure auto-tagging is enabled so Google Ads can automatically append a gclid parameter to the URL of each ad click. This parameter lets GA4 recognize traffic from your Google Ads campaigns.

Note: It’s best practice to keep auto-tagging enabled, as it allows GA4 to automatically distinguish Google Ads traffic from organic or referral sources.

  1. Once you’ve configured these settings, click Next and Submit to finalize the link.

To verify that the GA4-Google Ads link is working:

  1. Go to the Google Ads account and look for conversions or audience data coming from GA4.
  2. In GA4, go to Acquisition > User acquisition and confirm that Google Ads traffic appears as a source.

Benefits of Linking GA4 to Google Ads #

From my experience, linking GA4 and Google Ads provides a deeper understanding of ad performance and audience behavior. Here are some key benefits:

  1. Enhanced Conversion Tracking: GA4 enables more precise conversion tracking, including cross-device and cross-platform conversions, giving a full view of the user journey.
  2. Remarketing Audiences: You can create highly targeted remarketing audiences based on GA4 events, such as specific page views, video completions, or other in-app actions, for better ad targeting.
  3. Optimized Ad Spend: By monitoring user engagement and revenue generated from ads, you can identify high-performing keywords, demographics, or locations, allowing for optimized budget allocation.
  4. Detailed Reports: GA4 provides in-depth metrics about how users from Google Ads engage with your website or app, such as engagement time, pages viewed per session, and conversions.

Additional Optimization Tips #

After linking GA4 with Google Ads, consider using the following strategies to optimize your advertising efforts:

  • Use GA4 Audiences for Remarketing: Create custom audiences in GA4 and import them into Google Ads for remarketing campaigns.
  • Analyze Conversion Paths: Check GA4’s attribution and path analysis reports to understand how Google Ads and other traffic sources contribute to conversions over time.
  • Monitor Cost-Per-Acquisition (CPA): By tracking conversions and revenue, you can calculate and adjust your target CPA, which helps optimize bidding strategies in Google Ads.

Troubleshooting Common Issues #

  • Missing Conversion Data: Ensure that conversions are set up correctly in GA4 and marked as primary conversions for Google Ads.
  • Audience Syncing Delays: Audience data may take time to sync, especially if newly created in GA4. Allow up to 48 hours for Google Ads to populate with new audiences.
  • Discrepancies in Conversion Data: Minor discrepancies are common due to differences in attribution models between GA4 and Google Ads. GA4 uses last-click attribution by default, while Google Ads may use data-driven or position-based attribution.

Linking GA4 to Google Ads is a simple yet powerful step that can transform how you track and optimize advertising efforts. It provides a clearer picture of ad impact and helps refine your strategy to maximize returns.
