# Google Signals and Consent Mode: What Changed in 2026

##  At a Glance

    Key Takeaways  - From June 15, 2026, ad_storage exclusively controls whether advertising data flows into Google Ads. Google Signals no longer plays a role in that decision.
- Google Signals continues to govern enriched reporting data within Google Analytics.
- Advertisers without Consent Mode configured, or with ad_storage set to granted by default, may face meaningful regulatory compliance exposure.
- Three distinct risk scenarios apply depending on your current configuration.
- Your privacy disclosures may also need updating to reflect the new data flow.

Google’s June 2026 update decouples Google Signals from ad_storage, making Consent Mode the sole gatekeeper for advertising data flowing into Google Ads. For EMEA advertisers using GA4, the change has direct implications for GDPR compliance and campaign performance. This article explains what changed, what did not, and what to check in your configuration.

Google’s June 2026 changes to Google Signals have been framed primarily as a technical simplification. In most of the documentation Google has issued, the consent and privacy implications are treated as secondary, tucked into FAQ sections and framed as warnings rather than obligations.

That framing creates real risk for advertisers operating in the European Economic Area (EEA) and the UK, where the collection and processing of advertising data without valid consent is a legal question, not a configuration one.

This article explores what you need to get right from a consent perspective, and what that means for how you configure your tags.

## What Actually Changed on June 15, 2026

Until June 15, 2026, Google Signals and [Consent Mode](https://usercentrics.com/usercentrics-cmp-and-google-consent-mode-v2/) shared responsibility for controlling how advertising data from your Google Analytics tag was used in Google Ads. That joint control has now been replaced by destination-specific settings: one for Google Analytics, one for Google Ads.

### The Old Architecture

Prior to June 15, 2026, two settings jointly controlled whether Google Ads cookies and IDs collected via the Google Analytics tag and Firebase SDK were used in Google Ads: the Google Signals toggle in your GA4 property, and your Consent Mode ad_storage signal.

In practical terms, that meant an advertiser who had Google Signals switched off could still find that advertising data was being processed in Google Ads if ad_storage was set to granted — or vice versa. The two controls were coupled in a way that created ambiguity about which setting was actually governing data use.

### The New Architecture

Following the change, the two destinations operate under independent controls:

- **Google Analytics (behavioral reporting):** Controlled exclusively by the Google Signals setting and API
- **Google Ads (and the GA advertising section):** Controlled exclusively by Consent Mode ad_storage

The change brings the Google Analytics tag into parity with the Google Ads tag, which has always relied on ad_storage alone to gate advertising data. If you already use Google Ads tags, you are familiar with this model.

### What Did Not Change

analytics_storage continues to govern standard analytics data collection in GA4. No other Consent Mode signals, including ad_user_data and ad_personalization, are affected by this update. Google Signals remains useful for enhanced reporting (demographics and interests data) within Google Analytics for signed-in Google users with Ads Personalization enabled.

## Why the Consent Layer Comes First

The technical change is straightforward. The compliance implication is not. Under the [GDPR](https://usercentrics.com/knowledge-hub/the-eu-general-data-protection-regulation/) and the [Google EU user consent policy](https://www.google.com/about/company/user-consent-policy/), advertisers operating in the EEA must collect valid consent before personal data is used for advertising purposes. That obligation exists independently of how Google’s systems are configured.

The Consent Mode framework is the mechanism through which you communicate consent signals to Google’s tags, but the framework only supports compliance if it is correctly implemented.

The critical principle to hold onto is this: **consent signals govern Google Signals, not the other way around.** The question is never “is Google Signals on?” The question is “does my Consent Mode configuration correctly reflect the consent that visitors have given, and does it prevent advertising data from being processed where consent has not been given?”

## Three Risk Scenarios to Assess

The following scenarios reflect the most common configuration states and their associated risk profiles. They are not exhaustive, and none of this constitutes legal advice. Your compliance and/or legal teams should be involved in any compliance assessment.

### Scenario 1: No Consent Mode Configuration

If your site has no Consent Mode implementation, Google tags operate in their standard default state. That means ad_storage is active. Web and app activity will be associated with Google’s signed-in user information and used to improve advertising features, regardless of whether the visitor has given consent.

For advertisers subject to GDPR or the Google EU user consent policy, this represents significant compliance exposure.

### Scenario 2: Google Signals Active, Consent Mode Incorrectly Configured

If Google Signals is enabled but ad_storage is not correctly set to denied by default before consent is collected, enriched data (including signed-in user information) may flow into Google Ads without a valid consent basis. Following the June 2026 change, ad_storage alone now gates this data flow, so any misconfiguration here carries direct consequences.

This scenario is particularly common among advertisers who implemented Consent Mode some time ago and have not reviewed their default consent states since.

### Scenario 3: Correctly Configured, but Google Signals Not Reviewed

If your Consent Mode implementation is sound, with ad_storage denied by default and updated correctly upon consent, but you have not reviewed your Google Signals configuration since the change, you may be leaving consented data underutilized.

Enriched audiences and bidding signals that would legitimately be available to your campaigns may not be flowing correctly. This scenario carries no compliance risk, but it does represent unnecessary performance loss.

## What to Check in Your Configuration

The following checks are a starting point. How they apply to your specific setup will depend on your tag implementation, your consent management platform, and your regional obligations.

### Check 1: Is Consent Mode Implemented?

If not, this is the most urgent priority. Without Consent Mode, your tags operate as if consent has been granted.

### Check 2: Are Your Default Consent States Set to ‘Denied’?

For EEA visitors, both ad_storage and analytics_storage should default to denied prior to any consent interaction. Granted states should only be sent following a positive consent signal from the visitor.

### Check 3: Is Your Consent Management Platform (CMP) Correctly Passing Consent Signals to Google?

The Consent Mode configuration must be connected to your CMP so that the correct signal is sent to Google’s tags in real time, based on visitor choice.

### Check 4: Do Your Privacy Disclosures Reflect the Current Data Flow?

Following the change, the description of how advertising data is collected and used may need to be updated. Google has indicated that advertisers using a Google-certified CMP may be better positioned to manage this requirement — but your legal team should confirm what disclosure language is appropriate for your jurisdiction.
