What does the HubSpot Google Ads integration do?
It connects Google Ads to HubSpot's ads tool. HubSpot adds tracking to your ads so contacts are attributed to the ad they clicked, syncs leads from Google lead forms, builds audiences from HubSpot segments and site visitors, and sends conversion events such as lifecycle stage changes back to Google so bidding can optimize for real pipeline.
This guide follows HubSpot's and Google's documentation as of October 2026. The two don't always agree on details, so where they differ we say which source we followed and why.
What do you need to connect Google Ads to HubSpot?
Admin access to an individual Google Ads account, not a manager account, and ads publishing permission in HubSpot. Tracking, reporting and lead syncing work on all HubSpot plans. Conversion events and contact-segment audiences need Marketing Hub Starter or above, and the full attribution reports and ROI settings need Professional or Enterprise.
| Feature | HubSpot plan, October 2026 |
|---|---|
| Connect, auto-tracking, ads reporting, lead sync | All plans |
| Website visitor audiences | All plans; page filters need Starter |
| Contact segment audiences, conversion events | Marketing Hub Starter, Professional, Enterprise |
| All attribution models, ROI settings | Marketing Hub Professional, Enterprise |
HubSpot's Marketplace listing marks every feature as free, but its knowledge base gives the tiers above, which is what we follow. Conversion event counts are limited by tier: five on Starter, 50 on Professional and 100 on Enterprise.
How does HubSpot track Google Ads?
With auto-tracking on, HubSpot sets a campaign tracking template that adds UTM and HubSpot parameters to your ad URLs, so a contact who clicks and converts is attributed to that ad. Attribution only starts once auto-tracking is on. Any existing template must be blank or start with the landing page placeholder, and YouTube ads aren't tracked.
- Final URLs: point ads at the full, final page URL. Redirects and most link shorteners break tracking.
- Renamed campaigns keep their original campaign parameter.
- Deals in reports must be closed won, with a close date, and the contact in HubSpot's default Customer stage. Custom lifecycle stages aren't included.
How do you send HubSpot conversions to Google Ads?
On Marketing Hub Starter or above, create a conversion event in HubSpot's ads settings, triggered by a lifecycle stage change, such as to SQL, or a HubSpot form submission. HubSpot sends it to Google with the click ID or hashed contact data. Only changes after you create the event count, and each form can trigger one event.
- 01 Ad clickClick ID captured
- 02 ContactForm or tracking
- 03 Stage changee.g. to SQL
- 04 Event sentClick ID or hashed data
- 05 BiddingOptimizes on pipeline
- Value: events use a fixed value; HubSpot removed the option to use the deal amount.
- Timing: Google expects uploads within 24 hours of the conversion.
- Manager accounts: accounts under a Google manager account can't sync form data for conversions.
- 2026 changes: Google says enhanced conversions became one setting from June 2026, and offline conversion imports moved to its Data Manager API from 15 June 2026. Check the conversion action in Google Ads after setup.

How do Google lead forms and audiences work with HubSpot?
Turn on lead syncing for Google lead forms attached to campaigns, with auto-tagging on; leads sync from that point, with no history. For audiences, HubSpot sends hashed contact data from segments to Google's Customer Match, or builds website visitor audiences from HubSpot tracking. Google needs EU consent signals for EEA contacts and takes up to 48 hours to match.
- Consent: for people in the EEA, Google requires consent for ad user data and ad personalization. Build audiences from segments filtered on legal basis.
- Size: lists need enough matched users before Google will serve them, so small segments may not run.
- Lead data arrives in HubSpot as form submissions, and custom answers become text properties.
What happens if you disconnect Google Ads?
Your HubSpot data stays, but audiences stop syncing and conversion events are deleted from HubSpot, though they remain in Google Ads and don't return if you reconnect. Remove HubSpot's tracking template at account and campaign level yourself, and unlink HubSpot's manager account in Google Ads if you're leaving for good.
HubSpot Google Ads checklist
Key takeaway: Connect the account, keep auto-tracking on, and send lifecycle-stage conversions so Google bids on pipeline, not just form fills. Check the conversion setup in Google Ads after its 2026 changes.
Frequently asked questions
What does the HubSpot Google Ads integration do?
It connects a Google Ads account to HubSpot's ads tool. HubSpot adds tracking parameters to your ads so contacts are attributed to the ad they clicked, syncs leads from Google lead forms, builds audiences from HubSpot segments and website visitors, and sends conversion events, such as lifecycle stage changes, back to Google.
Which HubSpot plan do you need for Google Ads?
Connecting, ad tracking, reporting and lead syncing were available on all HubSpot plans when we checked in October 2026. Conversion events and audiences built from contact segments need Marketing Hub Starter or above, and the full set of attribution reports and ROI settings needs Professional or Enterprise.
Can you connect a Google Ads manager account to HubSpot?
No. HubSpot only connects individual Google Ads accounts, not manager accounts, and you need admin access to each. HubSpot links the account to its own manager account to manage tracking, and accounts under a manager account can't sync form data for conversions.
How do HubSpot conversion events work with Google Ads?
HubSpot sends a conversion to Google when a contact who clicked a Google ad reaches a lifecycle stage or submits a HubSpot form, using the click ID or hashed contact data. Only changes after you create the event count, each form can trigger one event, and events use a fixed value rather than the deal amount.
What changed with Google Ads conversions in 2026?
Google said that from June 2026 enhanced conversions for web and leads become one setting, and that from 15 June 2026 offline conversion imports move from the Google Ads API to its Data Manager API. HubSpot's setup article hadn't reflected this when we checked in October 2026, so confirm in Google Ads after setup.
