Google’s Upcoming Analytics & Ads Changes: Why You Need to Audit Consent Mode Before 15th June 

Google is rolling out major updates that reshape how data is governed across Google Analytics (GA4) and Google Ads. These changes streamline duplicated controls, strengthen privacy enforcement, and shift more responsibility to Consent Mode – especially the ad_storage parameter. 

For brands, this means one thing: your Consent Mode setup becomes mission‑critical. 

What’s Changing 

1. Google Signals Control Moves Fully to Consent Mode (15th June 2026) 

From June 15, Consent Mode becomes the sole authority for determining whether Google Ads cookies and identifiers can be collected. 

• If ad_storage = granted, full tracking is allowed. 
• If ad_storage = denied, only anonymous pings are sent — dramatically limiting Ads measurement and optimisation. 

The Google Signals toggle in GA4 will only control whether Analytics can associate data with signed‑in Google users for reporting. 

2. Ads Personalisation Will Be Controlled Exclusively in Google Ads (Later in 2026) 

Google is consolidating personalization settings so that Ads becomes the single decision-maker for how Analytics data is used in ad personalisation. Consent Mode’s ad_personalization setting will govern this. 

3. IP Address Handling Is Changing 

Google tags will continue to collect IP addresses, but they will be encrypted and passed to Google Ads, which will determine how they’re used based on Ads account settings. 

Why This Matters for Your Business 

These updates place Consent Mode — and specifically the ad_storage parameter — at the centre of your measurement strategy. If ad_storage isn’t implemented correctly, or if consent is denied by default, your Ads performance data will degrade significantly. 

This is especially important for: 

• conversion modelling 
• remarketing 
• audience building 
• attribution accuracy 

What You Need to Do Now 

Audit your Consent Mode setup ahead of the 15th June deadline. 

This includes: 

• verifying that ad_storage is firing correctly 
• ensuring consent defaults align with your legal and performance needs
• checking that consent signals are passed consistently across all pages
• confirming that GA4 and Google Ads are receiving the same consent state 

If you’d like support reviewing or upgrading your Consent Mode implementation, our team can help ensure you’re fully prepared before the deadline.

Google’s 15th June Update: Why You Need to Audit Consent Mode Now 

Google is making significant changes to how Analytics and Ads share and govern data. The biggest shift: Consent Mode becomes the single control point for Google Ads cookies and identifiers from 15th June 2026. 

This makes the ad_storage parameter essential: 

• ad_storage = granted → full tracking 
• ad_storage = denied → anonymous pings only 

If ad_storage isn’t implemented correctly, Ads measurement, modelling, and optimisation will be heavily restricted. 

Key Updates 

• Google Signals control moves fully to Consent Mode 
• Ads personalisation settings will be consolidated later in 2026 
• IP addresses will be encrypted and managed within Google Ads 

What You Should Do 

We strongly recommend auditing your Consent Mode setup now to ensure: 

• ad_storage is configured correctly 
• consent signals are passed consistently 
• your setup supports accurate Ads measurement 

If you’d like us to review your implementation, we’re ready to help.

Google’s latest Analytics & Ads update puts Consent Mode at the centre of your measurement strategy — and the deadline is approaching fast. 

From 15th June 2026, Consent Mode becomes the single authority for collecting Google Ads cookies and identifiers. That means the ad_storage parameter now carries real weight: 

• Granted = full tracking 
• Denied = anonymous pings only 

If your Consent Mode setup isn’t correct, your Ads performance data, modelling, and optimisation will suffer. 

Later in 2026, Google will also consolidate ads personalization controls and shift more governance into Google Ads. IP handling is being updated too, with encrypted IPs flowing directly to Ads. 

Now is the time to audit your Consent Mode implementation — especially ad_storage — to ensure your business is ready for the transition.
