If you’re responsible for managing HubSpot and Google Ads, you already know how closely these tools are tied. But when you’re juggling multiple ad accounts or transitioning ownership, you cannot afford to let old or irrelevant data clog your reporting.
One disconnected Google Ads account can mean the difference between accurate attribution and a tangled mess of vanity metrics.
Maybe you’re switching agencies, restructuring ad campaigns, or simply offboarding a test account. Whatever the reason, ensuring your Google Ads and HubSpot integration stays clean is critical for tracking actual ROI.
If left unaddressed, outdated ad connections can lead to incorrect contact attributions, sync errors, or wasted budget on reports that no longer reflect what’s happening.
This guide walks you through how to properly disconnect a Google Ads account from HubSpot, what happens when you do, how to fix the most common errors, and what to monitor next to keep campaign data accurate.
Stopping Google Ads Sync in HubSpot
Inside your HubSpot portal under the Marketing > Ads section, you’ll find the integration settings where your Google Ads account connects to HubSpot. This link allows HubSpot to automatically pull in your ad metrics, spend, impressions, clicks, and map that data to contacts in your CRM.
When you disconnect, you are breaking that link entirely. Here’s what that change triggers:
- Ad data from Google Ads stops syncing into HubSpot
- Contacts are no longer attributed to Google Ads activity
- Google campaign activity will not appear in your HubSpot dashboards
Each ad platform, Google, Facebook, and LinkedIn, operates independently within HubSpot. Disconnecting one will not affect the others.
This feature is typically managed by whoever oversees RevOps, paid media, or CRM hygiene. If your team runs operations across multiple accounts or regions, keeping each link intentional and current helps avoid costly data pollution.
How It Works Under the Hood
To properly disconnect the integration, it is worth knowing what makes it run.
When you connect your Google Ads account to HubSpot, you provide OAuth credentials, which grant HubSpot access to your campaign data. Once connected, HubSpot:
- Imports campaign, ad group, and ad-level performance data
- Inserts tracking parameters (like hsa_* values) into live ad URLs
- Syncs click data to contact records in real-time or close to it
Those background processes run on a schedule, typically once a day unless manually triggered. If Google-side access is revoked, HubSpot will still try syncing and simply flag a “Not Connected” status until you formally disconnect.
A full disconnect removes these live sync attempts but keeps historical data available for reference. That means:
- Stats like cost-per-click and impressions remain for old campaigns
- No new contact attribution ties to that Google Ads account
- UTM tracking stops unless you have manually embedded those links
Optional settings that affect how smoothly data flows include whether auto-tracking is enabled, how attribution rules credit ad interactions to contacts, and whether multiple Google Ads accounts are linked to the same portal.
Disconnecting halts sync, but does not clean up ad URLs or rebuild your dashboards. You will want to handle those manually if the account you removed is still sending traffic elsewhere.
Main Uses Inside HubSpot
Maintain Clean Data Across Accounts
When you manage several ad accounts in one HubSpot portal, across regions or products, it is easy for old data to overstay its welcome. Leaving disconnected or inactive accounts hooked into your portal will skew performance reports.
Example: If you are reporting on lead generation from a current campaign and an unrelated test account is still syncing cost data, your CPL will not reflect reality. Disconnecting unused accounts keeps your attribution honest and budgeting realistic.
Resolve Sync or Permission Issues
Authentication problems are common, especially when team members leave or Google access changes. Instead of diagnosing every failed token refresh, disconnect the Google Ads account in HubSpot, ensure valid permissions on the Google side, and reconnect it. This often resolves tracking or visibility errors instantly.
Manage Agency Offboarding or Transition
If you are moving from one agency to another or bringing ad management in-house, disconnecting old accounts prevents their data from cluttering dashboards or exposing it to former users. Always remove outdated connections before making new ones.
Protect Attribution Accuracy
Campaign attribution is only as clean as the integrations behind it. Disconnecting unused accounts stops HubSpot from tagging new contacts with obsolete source codes and keeps reporting aligned with reality.
Common Setup Errors and Wrong Assumptions
- Removing access in Google Ads but skipping HubSpot: Unlinking only on Google does not stop HubSpot from syncing. The account remains listed unless removed directly.
- Assuming disconnection deletes old data: Disconnecting stops future syncing, it does not erase historical reports.
- Not cleaning up tracking parameters: HubSpot tracking parameters may remain in ad URLs after disconnection. Remove or replace them if ads are still running.
- Ignoring user access cleanup: Even after disconnecting, the same Google user login could reconnect during account maintenance. Audit user roles as part of the process.
Step-by-Step Setup or Use Guide
Before you start, ensure you have Super Admin or Marketing Admin rights in HubSpot, plus access to the connected Google Ads credentials.
Steps:
- Log into HubSpot and go to Marketing > Ads
- In the dashboard, click Settings (top-right corner)
- Under “Connected accounts,” find the Google Ads account
- Click the Actions dropdown next to that account
- Choose Disconnect
- Confirm disconnection when prompted
- Optionally, visit myaccount.google.com/permissions and remove HubSpot’s access
- Refresh your HubSpot Ads dashboard to confirm the account shows as “Disconnected” or removed
- Reconnect if needed through Marketing > Ads > Connect Account
Measuring Results in HubSpot
After disconnecting, review how it affects marketing data:
- Ads performance dashboard: No new data should sync from the old account
- Contact attribution reports: New contacts should not reflect touchpoints from disconnected campaigns
- Website analytics: Check traffic tagged with old HubSpot UTMs and update manually if needed
- Custom reports: Compare pre- and post-disconnect metrics for anomalies
Monitor key fields such as account status labels and “Attribution Source” in CRM contacts. Remove any widgets or automations still relying on live ad sync data.
Short Example That Ties It Together
A marketing manager ran campaigns for a previous client last year. Those campaigns stopped, but the Google Ads account remained linked to HubSpot. Spend data continued flowing into dashboards, skewing CPL calculations.
They logged into HubSpot, disconnected the old account, and confirmed historical data remained for audits. Then they connected the current advertiser’s Google Ads account with updated credentials. Reporting was now clean, accurate, and aligned with active campaigns.
