How to Fix Google Ads Connection Issues in Hubspot

When your Google Ads account disconnects from Hubspot or stops syncing properly, ad performance data, reporting, and automation can quickly break. This step-by-step guide walks you through every recommended check to restore a stable, secure integration.

The instructions in this article are based on the official documentation from HubSpot's Google Ads troubleshooting guide, organized into a practical workflow so you can resolve issues fast.

1. Confirm Basic Google Ads Connection Requirements for Hubspot

Before diving into deeper fixes, make sure your setup satisfies the core requirements for connecting Google Ads to Hubspot.

1.1 Check Google User Access Level

The Google account you use to connect with Hubspot must have sufficient permissions in Google Ads. Verify that:

You are signed into the correct Google account.
Your user role in the relevant Google Ads account is at least Standard or Admin.
You are not removed or restricted in the Google Ads account.

If your user permissions were changed after the original connection, Hubspot may lose access, causing sync failures.

1.2 Verify Google Ads Account Status

Hubspot can only sync with active and compliant Google Ads accounts. In Google Ads, confirm that:

The account is not suspended.
Billing information is valid and up to date.
There are no unresolved policy violations preventing ads from serving.

Fix any account-level problems in Google Ads first, then return to your Hubspot ads settings to refresh the connection.

2. Review Permissions Granted to Hubspot in Google

For the integration to work, Hubspot needs specific access scopes granted through your Google account. If these permissions were revoked, the ads tool may disconnect.

2.1 Inspect Third-Party Access in Your Google Account

Sign in to the Google account that should be connected to Hubspot.
Go to Security > Third-party access (or similar, depending on the Google interface).
Locate the application entry for Hubspot.
Confirm that access is still granted and not limited or revoked.

If access has been removed, Hubspot will no longer be able to read or manage Google Ads data. In that case, you will need to reconnect from within the Hubspot ads settings.

2.2 Reconnect Google Ads from Hubspot

To reestablish proper permission scopes:

In Hubspot, navigate to Marketing > Ads.
Click the Settings icon in the ads dashboard.
Under the connected accounts section, locate your Google Ads connection.
If you see a warning or disconnected status, choose the option to Reconnect or Connect account.
Follow the Google authorization flow and accept all requested permissions for Hubspot.

After reconnecting, check whether your campaigns, ad groups, and ads begin to sync normally again.

3. Fix Missing or Partial Data Sync Between Hubspot and Google Ads

Sometimes the connection appears active, but certain campaigns or metrics do not show up in Hubspot. Use the checks below to isolate the cause.

3.1 Confirm the Right Google Ads Accounts Are Connected

If you manage multiple Google Ads accounts (including MCC or manager accounts), it is easy to connect the wrong one to Hubspot. To verify:

Open Hubspot ads settings and view the list of connected Google Ads accounts.
Compare the customer IDs with the accounts you expect to sync.
If an incorrect account is connected, disconnect it and connect the correct Google Ads account.

Only the specific Google Ads accounts you explicitly connect will send data into Hubspot.

3.2 Check Date Ranges and Filters in Hubspot

In some cases, data appears missing simply because of filters:

Make sure the date range in the Hubspot ads dashboard covers the period when campaigns were running.
Clear or adjust campaign filters to ensure you are not hiding the campaigns you want to monitor.

Once filters and date ranges are correct, reevaluate whether all expected ads and metrics are present.

3.3 Allow Time for Initial Sync

Right after you first connect Google Ads to Hubspot, the initial data sync can take time. Depending on account size, this may be up to several hours. During this window:

Not all historical campaigns may appear instantly.
Conversions and contact attribution may populate gradually.

If you just connected the account, wait and refresh the Hubspot ads dashboard before assuming something is broken.

4. Troubleshoot Conversion Tracking Issues in Hubspot

Accurate lead and contact attribution is a major reason to connect Google Ads to Hubspot. If conversions do not match between the two systems, use the following checks.

4.1 Verify Hubspot Tracking Code on Your Site

The Hubspot tracking code must be properly installed on all pages where you expect to track visits and conversions.

In Hubspot, go to your tracking code settings and copy the script snippet.
Confirm that the code is present in the <head> section of your website templates or via tag manager.
Test a visit and form submission to make sure events show up in Hubspot analytics.

Without this tracking code, Hubspot cannot associate Google Ads clicks with contacts or sessions.

4.2 Ensure Auto-Tracking for Google Ads Is Enabled

Hubspot can automatically apply tracking parameters to Google Ads, which helps with attribution:

In the Hubspot ads tool settings, verify that auto-tracking for Google Ads is switched on.
If it was turned off, enable it and monitor new clicks and conversions going forward.

Note that previously untracked clicks cannot be retroactively fixed, but new data will sync correctly once auto-tracking is active.

4.3 Compare Conversions with Awareness of Attribution Differences

Hubspot and Google Ads use different attribution models and conversion definitions. Expect some variance in counts when:

Google Ads tracks every conversion action configured in its account.
Hubspot focuses on contact creation, lifecycle changes, and custom events based on your CRM configuration.

When troubleshooting, confirm you are comparing similar metrics and time windows in both tools.

5. Resolve Common Error Messages in Hubspot Ads

When problems persist, you may see error messages or warnings in the Hubspot ads interface. While exact wording can vary, most errors relate to permissions, account status, or tracking.

5.1 Typical Causes of Google Ads Errors in Hubspot

Revoked or expired Google authorization tokens.
Lowered user permissions in Google Ads.
Suspended or closed Google Ads accounts.
Blocked third-party access or disabled APIs.

When you see a specific error, Hubspot will usually provide a brief description and, sometimes, a link to recommended steps. Follow those instructions first, then re-test by refreshing the ads dashboard.

5.2 When to Disconnect and Reconnect Entirely

If simpler fixes do not resolve the problem, a full reconnect may be required:

In Hubspot ads settings, disconnect the problematic Google Ads account.
In your Google account security settings, remove Hubspot's third-party access.
Return to Hubspot and connect Google Ads again from scratch.
Accept all permission prompts and confirm the correct account IDs.

This reset often resolves stubborn sync or authorization issues that are not fixed by a simple reconnect.

6. Best Practices to Keep Your Hubspot–Google Ads Integration Stable

After you restore a healthy connection, follow these ongoing best practices to avoid future disruptions between Google Ads and Hubspot.

Do not downgrade or remove the Google user that authenticated the integration without updating the connection in Hubspot.
Monitor Google Ads billing and policy notifications so account suspensions do not surprise you.
Regularly check that the Hubspot tracking code remains installed across any new or redesigned pages.
Document which Google account and permissions are used for the integration so your team can manage changes safely.

Keeping a simple internal playbook will significantly reduce connection problems as your team or account structure evolves.

7. When to Seek Extra Help Beyond Hubspot Docs

If you have walked through all the steps above and still experience issues, consider additional support.

Consult the original, detailed Hubspot documentation: Troubleshoot your Google Ads account connection.
