Hupspot guide to Google Consent Mode
Modern analytics and advertising depend on data, and many teams using Hubspot also rely on Google tools. To stay compliant with privacy regulations like GDPR while still measuring performance, you need a clear implementation of Google Consent Mode that works smoothly alongside Hubspot campaigns and tracking.
This step-by-step guide breaks down how Google Consent Mode works, how it affects your analytics and ads, and what marketers should do to keep measurement reliable while honoring user choices.
What Google Consent Mode is and why Hubspot users should care
Google Consent Mode is a framework that lets your website adjust how Google tags behave based on each visitor’s consent preferences. Instead of a simple on/off switch for tracking, it provides a more nuanced way to collect data in a privacy-conscious manner.
If you run campaigns in Google Ads, use Google Analytics, and manage your inbound strategy with Hubspot, Consent Mode helps you:
- Respect regional privacy laws and user choices.
- Preserve key measurement signals for optimization.
- Reduce data loss caused by blanket cookie blocking.
In short, it helps balance compliance and performance.
How Google Consent Mode works with key Google tags
Consent Mode communicates a visitor’s consent state to Google tags using special parameters. These parameters tell tags whether they may use cookies and other identifiers for specific purposes like ads or analytics.
Core consent states
There are several consent types and states that matter for marketers:
- ad_storage – Controls advertising cookies and identifiers for remarketing and conversion tracking.
- analytics_storage – Controls analytics cookies used by Google Analytics and related tools.
- functionality_storage – Manages cookies needed for site features (such as language preferences).
- security_storage – Focuses on security-related storage such as fraud prevention.
Each of these can be set to values such as “granted” or “denied” based on your consent banner choices.
Behavior with and without consent
When visitors grant consent, your Google tags behave normally. When they deny consent, tags switch to a limited mode. In this limited mode:
- No advertising cookies are set for disallowed purposes.
- Requests may still be sent, but with reduced identifiers.
- Data can be modeled in aggregate to help fill measurement gaps.
That means you can still see trends and conversions without tying data to specific individuals in restricted situations.
Hubspot marketer checklist before implementing Consent Mode
Before you add Consent Mode to your stack, review how your site currently handles data. Many teams using Hubspot run multiple tools side by side, so you want a clear map of everything that sets cookies or tracks events.
- Audit your tags and pixels
- List all Google tags (Analytics, Ads, Tag Manager, Floodlight, etc.).
- Note any other third-party pixels (social, programmatic, affiliate).
- Review your consent banner and privacy policy
- Confirm which categories of cookies your banner controls.
- Ensure your documentation clearly explains analytics and ads usage.
- Align consent categories
- Map your consent banner categories to the Google Consent parameters.
- Decide which features require explicit opt‑in.

Step-by-step: Implementing Google Consent Mode for sites powered by Hubspot
Implementation details vary depending on your stack, but the general sequence is consistent. Below is a high-level process that works whether you use Google Tag Manager or hard-coded tags.
Step 1: Implement a compatible consent banner
Your consent banner or CMP (consent management platform) must be able to collect and store visitor preferences in a way that can be passed to Google tags. Core tasks:
- Display a clear banner for first-time visitors in relevant regions.
- Offer granular options for analytics and ads where required.
- Store preferences and allow users to change them later.
Step 2: Configure default consent states
Before users make a choice, you should define default settings that match your legal obligations. For example, in strict GDPR regions you might default analytics and ad storage to “denied” until explicit consent is given.
These defaults are declared in your tag configuration so that Google tools do not set disallowed cookies by accident before a user interacts with the banner.
Step 3: Update tags to respect consent
Next, connect your consent banner logic to Google tags. Typical actions include:
- Using Consent Mode APIs or tag manager templates to read consent choices.
- Passing consent values (such as “granted” or “denied”) to each Google tag.
- Ensuring tags update dynamically when users change their preferences.
When implemented correctly, tag behavior will automatically adjust with each visitor’s choice without requiring separate pixels.
Step 4: Test analytics and conversion tracking
After configuration, thoroughly validate your setup:
- Use browser developer tools and tag debugging extensions to inspect consent signals.
- Test flows with all consent granted, all denied, and mixed settings.
- Confirm that cookies are not set in violation of preferences.
- Compare reported conversions before and after implementation to understand impact.
Monitoring early behavior lets you adjust your Consent Mode configuration before you depend on new data for major optimization decisions.
How Consent Mode affects reporting and modeling for Hubspot campaigns
Consent Mode has a direct effect on how Google Analytics and Google Ads report performance, which in turn influences how you evaluate campaigns that run alongside Hubspot automation and email sequences.
Measurement with modeled conversions
When users deny certain storage types, Google may rely on modeled conversions to close data gaps. This modeling uses aggregated behavior from similar users who granted consent to estimate outcomes for those who did not.
For marketers, this means:
- Reported conversions can include both observed and modeled data.
- You maintain trend visibility even as privacy protections grow.
- Optimization algorithms still receive enough signals to function.
Attribution and funnel analysis
Consent Mode can influence attribution windows and paths. Because fewer identifying cookies may be available, some multi-touch paths appear shorter or more fragmented. In practice, you may observe:
- More emphasis on first-party data strategies.
- Greater variability in user-level paths compared with session-level metrics.
- The need to use blended reporting views that combine Google and Hubspot insights.
Best practices for privacy-first optimization with Hubspot
To make the most of Consent Mode while using Hubspot as a core marketing hub, adopt a privacy-first optimization mindset.
