If your remarketing lists never seem to stay up to date or you’re drowning in exported CSVs just to keep ad audiences relevant, you’re not alone. Many marketers waste budget on mismatched targeting, stale customer lists, and ad campaigns that miss high-intent leads, all because platform-to-platform audience syncing falls short.
HubSpot has a native way to fix this. Its built-in Ads tool connects directly to Google Ads and automatically syncs contact lists without manual uploads. But too many teams either skip the feature or misconfigure it, not realizing what they’re missing.
This guide breaks it all down for you, step by step. You’ll learn where the HubSpot-Google Ads sync lives, how to configure Customer Match, what mistakes to avoid, and how to measure campaign performance using CRM data.
You’ll walk away with examples you can apply to your campaigns today.
Using CRM Lists in HubSpot to Power Google Ads
HubSpot Audiences is a core part of the platform’s Ads toolset, allowing you to push CRM-based contact lists directly into ad networks like Google Ads, Facebook, and LinkedIn. Inside your portal, go to Marketing > Ads > Audiences to access it.
Once your ad account is connected, HubSpot syncs contacts automatically based on dynamic or static list criteria. For Google Ads, HubSpot leverages Google’s Customer Match feature, which matches first-party data, including email addresses, phone numbers, and mailing addresses when available and compliant, with signed-in users across Google services.
That means no more uploading spreadsheets to keep remarketing going. HubSpot keeps your lists live and reactive. If a contact submits a form or changes their lifecycle stage, your Google Ads audience is automatically updated. This connection allows CRM insights to feed directly into Google ad delivery, reducing targeting lag and removing guesswork.
How It Works Under the Hood
List Creation in HubSpot: Build a contact list using filters tied to form fills, lifecycle stages, recent behaviors, or deal data.
Audience Sync Setup: In the Audiences section, select your list and designate Google Ads as the sync destination.
Data Matching: HubSpot hashes user data for privacy and sends it to Google. Google matches the data to signed-in users in Gmail, YouTube, Search, and more.
Automatic Updates: HubSpot monitors contact records. If someone meets or no longer meets your criteria, the synced Google Ads audience updates accordingly.
Usage in Campaigns: Apply the synced audience to Google Ads campaigns for targeting, exclusions, or observation.
Feedback Loop: HubSpot pulls back campaign metrics like cost, clicks, impressions, and influenced contacts, so you can track impact from your CRM.
This integration lets your CRM act as the source of truth for audience eligibility, eliminating manual churn. You also gain flexibility:
- Use lifecycle stage filters to focus on leads, trials, or customers
- Ensure audiences meet Google’s minimum size, usually several hundred users
- Apply synced exclusion lists to prevent irrelevant ads from reaching your customer base
Main Uses Inside HubSpot
Upsell Offers to Existing Customers
Manually targeting your customer base with upsell campaigns can be time-consuming. With HubSpot synced to Google Ads, you don’t need spreadsheets or scheduled exports.
Example:
You sell a subscription SaaS product. Build a smart list in HubSpot for paying customers who haven’t upgraded to the premium plan. That list syncs to Google Ads for premium-only campaigns. Anyone who upgrades drops off automatically.
Lead Nurturing via Engagement Audiences
Track engagement like email opens, website visits, or downloads, and turn those behaviors into remarketing audiences.
Example:
A B2B SaaS team creates a smart list of leads who visited the pricing page multiple times but haven’t converted. That list syncs to Google Ads, and remarketing ads encourage demo bookings. Lists update in real time.
Excluding Customers from Acquisition Campaigns
Avoid showing “new customer” ads to existing buyers.
Example:
An eCommerce brand creates a smart list of “Closed-won” customers in HubSpot and syncs it to Google Ads as an exclusion audience. Past customers no longer see acquisition promotions.
Re-engagement for Dormant Leads
Some qualified leads go cold. Surface your brand again without manually reloading contact data.
Example:
A company pulls “Closed-lost” contacts older than 90 days and syncs them to Google Ads. They run display ads with tailored messaging. Re-engaged leads enter nurture flows automatically.
Common Setup Errors and Wrong Assumptions
- Audience size too small: Google Ads requires a minimum number of matches. Fix: Confirm your list has several hundred actionable emails.
- Google Ads permissions are too limited: Partial access stalls sync. Fix: Use an admin-level login.
- Static lists mistaken for dynamic: Static lists don’t auto-update. Fix: Use smart lists based on behavior or lifecycle stage.
- Poor contact hygiene: Bounced or unverified emails reduce match rates. Fix: Maintain clean, compliant data.
Step-by-Step Setup or Use Guide
Ensure you have: HubSpot Marketing Hub Professional or Enterprise, a connected Google Ads account with admin access, and verified contact data.
- Connect your Google Ads account
Go to Marketing > Ads, click Connect Account, and follow the prompts. - Build your contact list
Go to Contacts > Lists and create a smart list using filters like Lifecycle Stage or Last Activity Date. - Check contact quality
Confirm the list contains valid emails. Exclude bounced or unsubscribed contacts. - Sync the list to Ads
In Marketing > Ads > Audiences, choose Create Audience, attach your list, and select Google Ads. - Select Customer Match
Confirm the audience type and complete setup. - Wait for sync completion
Sync time may vary; larger lists take longer. - Apply the audience in Google Ads
In Google Ads, go to Tools > Shared Library > Audience Manager and apply to campaigns. - Monitor list health
Track sync status, member counts, and changes in HubSpot Ads > Audiences.
Measuring Results in HubSpot
- Performance overview: View cost, impressions, conversions, and influenced contacts per campaign.
- Audience growth tracked live: Review last sync times and activity.
- CRM attribution: Track contacts from each campaign to engagement and deals.
- Behavior vs. exposure: Compare conversion rates between synced and unexposed contacts.
- Integrated dashboards: Blend ad data with deals, MQLs, and revenue in HubSpot Reports.
Check Settings > Connected Accounts weekly to confirm continuous syncing.
Short Example That Ties It Together
A SaaS team wants to re-engage trial users who never upgraded. They create a smart list in HubSpot with filters: Lifecycle Stage = Lead, Last Activity Date > 60 days. Sync to Google Ads Customer Match.
Campaign drives these users to a demo landing page. Converted users are marked as Customer, which automatically removes them from the re-engagement list. CTR and CPA improve, and manual list updates are no longer needed.
