Once your foundational tracking is in place, the next step is to connect your data streams and verify everything is working correctly.
Best Practices for Integration and Verification:
A. HubSpot Tracking Code
B. The Google Ads Integration
HubSpot has a native integration with Google Ads. You need to connect your Google Ads account to HubSpot.
Why it's important: This integration automatically pulls in Google Ads data and attributes ad clicks to your HubSpot contacts. It also allows you to sync your HubSpot contact lists (e.g., "MQLs," "New App Installs") back to Google Ads for remarketing and audience targeting.
C. Tracking Conversions in HubSpot
You need to set up "Goals" in HubSpot that mirror your conversions in Google Ads.
Action: Create a goal for an "App Install" that is triggered when a contact reaches your post-install "Thank You" page. This connects the Google Ads click, the HubSpot contact, and the final conversion action.
The Final Debugging & "Best Practices" Checklist
Use the Tag Assistant Companion: This Google Chrome extension is a must-have. It shows you which tags are firing on your website and can help you debug why a conversion tag isn't firing correctly.
Verify Conversions in Google Ads: After implementing your tags, go to Tools & Settings > Conversions > Diagnostics in Google Ads. This will tell you if your conversion actions are receiving data and if there are any errors.
Link Accounts: Ensure your Google Ads and HubSpot accounts are properly linked. This is often an overlooked but critical step.
Audit Your Funnel: Manually walk through the entire user journey:
Click your own Google Ad.
Land on your website.
Click the "Install" button.
(If applicable) Get redirected back to your "Thank You" page.
As you do this, use the Tag Assistant to confirm every tag fires as expected at each step.
