HubSpot Guide to Google Tag Manager
Connecting HubSpot with Google Tag Manager gives marketers a flexible way to add tracking codes, measure behavior, and optimize campaigns without relying on developers for every small change.
This article walks through what Google Tag Manager (GTM) is, how it works, and how to use it effectively alongside your HubSpot tools so your analytics stay accurate and easy to manage.
What Is Google Tag Manager and Why Use It with HubSpot?
Google Tag Manager is a free tag management system from Google. Instead of placing multiple tracking scripts directly on your site, you place one GTM container snippet and then manage all tags from the GTM interface.
When you integrate it with HubSpot, you get a central hub where you can manage marketing and analytics tags while your CRM and automation handle leads and nurturing.
Key Benefits for HubSpot Users
- Faster deployment: Add or adjust tracking without editing your website code every time.
- Cleaner codebase: One container snippet replaces multiple standalone scripts.
- Better governance: Control who can publish or edit tags using GTM’s workspace and versioning.
- Improved reporting: Capture detailed behavioral data that complements reports you build in HubSpot.
How Google Tag Manager Works with HubSpot
Google Tag Manager uses three main components that line up well with your existing HubSpot setup.
Tags
Tags are snippets of code that send data to third-party systems. Common examples include:
- Google Analytics
- Google Ads conversion tracking
- Facebook (Meta) Pixel
- LinkedIn Insight Tag
- Custom HTML tags for specialized tools
When your website already has HubSpot tracking installed, GTM tags help expand what you track beyond standard page views and form submissions.
Triggers
Triggers tell GTM when a tag should fire. Examples include:
- Page views on a specific URL
- Clicks on a particular button or link
- Form submissions
- Scroll depth reaching a percentage of the page
These triggers work well alongside HubSpot workflows. For example, a form submission trigger in GTM can record a conversion while HubSpot captures the lead and updates lifecycle stages.
Variables
Variables provide dynamic information to your tags and triggers, such as:
- Page URL and hostname
- Click text or click classes
- Custom data layer values
Using variables means you can configure GTM in a scalable way while HubSpot stores high-value contact and company data.
Installing Google Tag Manager on Your Site
To use GTM with your marketing stack, start by installing the container snippet correctly on your website.
Step 1: Create a GTM Account and Container
- Go to Google Tag Manager.
- Sign in with your Google account.
- Create a new account and container, selecting “Web” as the target platform.
- Accept the terms of service.
GTM will provide two snippets of code: one for the <head> and one immediately after the opening <body> tag.
Step 2: Add the GTM Snippet to Your Site
Depending on how your site is built, choose one of the following approaches:
- CMS or theme editor: Paste the head and body snippets into your global template so they load on every page.
- Developer support: Ask your developer to add the snippets in the correct locations across the site.
Make sure any existing analytics scripts (like standalone Google Analytics) are removed or migrated into GTM to avoid double-counting.
Step 3: Preview and Publish
- In Google Tag Manager, click Preview.
- Enter your website URL and start the preview session.
- Verify that the container loads and any initial tags work as expected.
- Click Submit and then Publish to make the container live.
Using GTM to Enhance HubSpot Analytics
Once GTM is installed, you can configure tags that complement the data you already collect in HubSpot.
Track Micro-Conversions Beyond HubSpot Forms
While HubSpot provides strong form and page tracking, GTM lets you measure smaller interactions that matter to your funnel, such as:
- Clicks on CTAs that lead to external resources
- Video engagement (play, pause, percentage watched)
- Scroll depth on key landing pages
- Outbound link clicks to partner sites
These events can feed into your analytics platform and inform how you optimize landing pages, emails, and follow-up sequences.
Set Up Event Tracking with Google Analytics
To capture more granular events alongside HubSpot data, create an event tag in GTM for Google Analytics:
- Create a new tag and choose the Google Analytics configuration you use.
- Select an event type (for example, click or form submission).
- Define event parameters such as category, action, and label.
- Assign a trigger, such as “Click – All Elements” with conditions that match the element you want to track.
- Preview, test the interaction, and then publish.
This approach lets you build reports that show how visitors behave before or after milestones you manage with HubSpot, like content downloads or demo requests.
Best Practices for Running GTM with HubSpot
To keep your analytics reliable and your workflows efficient, follow a few governance and quality practices.
Maintain a Single Source of Truth
Decide where each type of data should live:
- Use HubSpot for contact-level insights, lifecycle stages, deals, and email engagement.
- Use GTM-connected analytics tools for page-level behavior and ad performance.
Document which conversions are counted in each platform so stakeholders interpret KPIs consistently.
Avoid Duplicate Tracking
Running both native scripts and GTM versions of the same tag can inflate metrics. For example, if Google Analytics is installed directly and via GTM, you will see duplicate page views.
Before adding a new tag in GTM, check if that script is already loaded from your site templates, HubSpot assets, or other integrations.
Use GTM Versions and Workspaces
GTM offers version history so you can roll back if something breaks. Use this to your advantage:
- Create a new workspace for larger changes.
- Test thoroughly with the preview mode.
- Publish often with clear version names and descriptions.
This keeps tracking stable while HubSpot continues to run your campaigns and automation.
