Starting August 3, 2026, Google will use IP addresses for ad measurement and personalization across the EEA, UK, and Switzerland — the first time it activates this signal in European markets. For affiliates running international offers on platforms like ClickBank, Digistore24, MaxWeb, or AdCombo, or anyone with European traffic in their Google Ads account, this triggers a direct consent obligation: without a correctly configured Google-certified CMP, your European conversion data is at risk.
Consent Mode is Google's system for transmitting user consent signals to all Google Ads and Analytics tags. It defines, via four parameters (ad_storage, analytics_storage, ad_user_data, and ad_personalization), what Google can collect and use based on each visitor's choice. Without Consent Mode correctly configured, Google treats European users as non-consented — and stops personalizing ads, building remarketing audiences, and accurately recording conversions for that traffic.
What Changes on August 3, 2026: IP-Based Personalization in the EEA
Google already received IP addresses as a byproduct of any integration with sites and apps. What changes on August 3 is the purpose: those IPs will now be used to identify devices and personalize ads in the EEA, UK, and Switzerland. Since an IP address is personal data under GDPR, this triggers a consent requirement. Google is implementing three privacy-enhancing technologies to make this possible — but they do not eliminate the need for user consent:
- On-device processing — computation stays local on the user's device rather than sending raw signals to external servers
- Trusted Execution Environments (TEEs) — isolated hardware enclaves where data is processed without exposure to the system operator
- Secure Multi-Party Computation (MPC) — joint computation between parties where neither can access the other's raw data
- IAB TCF Feature 3 registration — Google formally declares under the European consent framework that it identifies devices via automatically transmitted signals including IP; publishers using TCF-registered CMPs must ensure Feature 3 is surfaced for vendor ID 755 (Google)
The Change That Already Happened: ad_storage as the Sole Control (since June 15, 2026)
Before August, a critical change already took effect: since June 15, 2026, the ad_storage parameter in Consent Mode became the single parameter controlling what Google Ads receives. Google Signals lost that authority. Disabling Google Signals — a common tactic for limiting data sharing with Ads — no longer works as a privacy safeguard. The only lever that matters now is ad_storage, controlled by your CMP. If your CMP sets ad_storage to 'granted' by default for EEA users, you are sending data without valid consent under GDPR.
With ad_storage denied (user did not consent), Google Ads receives only the gclid URL parameter — nothing else. The practical consequences: remarketing lists stop growing for EEA traffic, conversion tracking is interrupted, audience targeting stops working, and your CPA model loses European signal. Using a non-certified CMP or one configured with Consent Mode v1 (two parameters instead of four) produces the same result — the consent signal does not reach Google correctly.
The Four Consent Mode v2 Parameters Every Affiliate Must Configure
Consent Mode v2 works with four parameters. All four must be present in both the default call (before any user interaction) and the update call (after the user makes a choice). For EEA traffic, all defaults must be 'denied' — updated to 'granted' only after active acceptance:
- ad_storage — controls the reading and writing of advertising cookies and device identifiers; became the master ad parameter since June 15, 2026
- analytics_storage — controls Analytics data collection; must follow the same denied-by-default logic as ad_storage for EEA traffic
- ad_user_data — controls whether first-party data (email, phone) can be sent to Google for hashed matching; without it, Enhanced Conversions does not work correctly
- ad_personalization — controls whether Analytics data can be used for personalized advertising; will become the sole personalization control when Google consolidates it under Google Ads (timing not yet announced)
What Is a Google-Certified CMP and Why You Need One
A CMP (Consent Management Platform) is the tool that displays the cookie banner, collects the user's choice, and transmits the correct signals to Consent Mode. Google-certified CMPs guarantee that all four Consent Mode v2 parameters are set correctly and respect jurisdiction-specific rules — denied by default for EEA, opt-out logic for other markets. Examples of Google-certified CMPs: Cookiebot, OneTrust, Usercentrics, UniConsent, CookieHub, Consentmanager. Non-certified CMPs or those still running Consent Mode v1 (two parameters) leave critical gaps in the signal Google receives.
Affiliates with Consent Mode v2 correctly configured unlock Google's conversion modeling: the algorithm estimates results from non-consented users based on patterns from those who accepted. Without this setup, conversions from non-consented EEA users simply vanish from your metrics — with no estimation, no modeling, and no way to recover the data after the fact.
The Direct Impact on Conversion Tracking and AdsTracking
For affiliates using AdsTracking to track sales on platforms like ClickBank, Digistore24, Hotmart, or Monetizze, the rule is clear: tracking tags must fire only after Consent Mode signals have been transmitted. If AdsTracking fires before ad_storage is defined, the conversion event is processed without the correct consent context for EEA traffic. The correct sequence: CMP sets the default for ad_storage — user interacts with the banner — CMP calls the Consent Mode update — AdsTracking fires with the correct context. Any deviation from this order creates compliance risk for European traffic.
Compliance Checklist: What to Verify Before August 3, 2026
If you run campaigns with any volume of European traffic:
- Confirm your CMP is Google-certified and supports Consent Mode v2 with all four parameters — Consent Mode v1 implementations (two parameters only) are insufficient
- Open your site in a private browser window before touching the cookie banner and verify: ad_storage must be 'denied' for EEA traffic — any 'granted' default before user interaction is a GDPR violation
- If you use a TCF-registered CMP, confirm that IAB Feature 3 is being surfaced for vendor ID 755 (Google) in the consent UI — contact your CMP provider before August 3 to verify this
- Confirm all four parameters (ad_storage, analytics_storage, ad_user_data, ad_personalization) are present in both default and update calls
- Ensure tracking tags fire only after the Consent Mode update — never before the user responds to the banner
- Cover every critical page: landing page, purchase confirmation page, and any subdomain running Google tags
Frequently Asked Questions About Google Consent Mode and the August 2026 Update
Do affiliates running campaigns only in Brazil or the US need to worry about this?
Directly, no — GDPR applies to EEA users, not to Brazilian or US audiences. But if your Google Ads account receives any European traffic (even incidental), the new rules apply to those users. Beyond compliance, Consent Mode v2 is a global best practice that improves conversion signal quality for all markets, including those outside the EEA. Getting it right for Europe does not hurt non-European campaigns.
What happens to my European campaigns if I don't configure a CMP by August 3?
Google does not suspend your campaigns — but it stops personalizing ads, building remarketing lists, and accurately recording conversions for users who are treated as non-consented. For Performance Max or Target CPA campaigns in European markets with high cookie refusal rates — Germany, France, the Netherlands — the performance impact can be significant and will appear as a silent degradation, not a clear error message.
What is the difference between having a privacy policy on the landing page and having Consent Mode?
They are separate layers. A privacy policy is a legal document that informs users about data collection. Consent Mode is the technical implementation that transmits the user's choice to Google tags in real time. You can have a legally perfect privacy policy and still not have Consent Mode — in which case Google receives no consent signal and treats the user as non-consented regardless of what the document says.
Does conversion modeling fully compensate for lost data from users who refuse consent?
Partially. Google's conversion modeling estimates results for non-consented users using patterns from those who accepted — but it requires a minimum volume of consented sessions to produce reliable estimates. In European markets with high refusal rates and smaller accounts, that volume threshold may not be met, making the modeling unreliable. This is why maximizing valid consents remains more important than relying on modeling to fill the gap.
Does this update affect Google Analytics data in addition to Google Ads?
Yes. Since the June 15, 2026 update, Google Analytics settings no longer independently control advertising data — Consent Mode is the single authority across both Analytics and Ads. IP addresses collected by Analytics tags are now encrypted before being forwarded to linked Ads accounts. This means your Analytics-to-Ads data pipeline is now governed entirely by the ad_storage signal from your CMP.
The Bottom Line
The August 2026 update makes operational what GDPR has always implied: IP is personal data in Europe, and using it for personalization requires valid consent. For affiliates with European traffic, the practical consequences are clear — without a certified CMP and Consent Mode v2 configured with all four parameters, European conversion tracking and targeting degrade silently. AdsTracking handles the technical precision of conversion events, but it depends on a correct consent context to work within the rules for EEA users.
