Google Ads is Google's advertising platform, enabling advertisers to run search, display, shopping, and video campaigns across Google's properties and the broader Google Display Network. It deploys a JavaScript tracking tag — the Google tag (gtag.js) — on advertiser websites to measure conversions, build remarketing audiences, and enable personalised ad targeting. Depending on configuration, Google Ads can operate as a basic conversion measurement tool or a comprehensive cross-device, cross-site advertising platform leveraging hashed first-party identity matching via Enhanced Conversions and Customer Match. Google LLC is headquartered in Mountain View, California, USA. For Google Ads, Google and the advertiser each operate as Independent Controllers of personal data under Google's Controller-Controller Data Protection Terms, in accordance with Article 4(7) GDPR. The configurations below cover the most privacy-relevant settings and their corresponding mappings in the Consenter Manager.


Step 1 — Google Ads Configuration

# Configuration Area Where in Google Ads Configuration A — Lower Risk Configuration B — Medium Risk Configuration C — Higher Risk
1 Consent mode implementation Google tag / Tag Manager → Consent Mode settings Basic Consent Mode: Google tag is fully blocked until explicit user consent is granted; no data sent to Google prior to consent interaction Basic Consent Mode: Google tag blocked until consent; no data sent to Google prior to consent interaction Advanced Consent Mode v2: Google tag loads with all consent signals set to denied by default; anonymous, cookieless pings sent to Google before consent; full tag fires only after consent is granted
2 Conversion tracking Google Ads → Goals → Conversions Standard conversion tracking (GCLID-based) only; fires only after consent; no Enhanced Conversions Standard conversion tracking (GCLID-based) plus Enhanced Conversions for Web (hashed email/phone collected on-site at point of conversion) Standard conversion tracking plus Enhanced Conversions for Web and Enhanced Conversions for Leads (hashed CRM data uploaded offline); conversion modelling active via Advanced Consent Mode
3 Remarketing audiences Google Ads → Shared Library → Audience Manager No remarketing audiences created; tag used for conversion measurement only Website visitor remarketing lists created; membership duration set to 30 days Website visitor remarketing lists plus Customer Match audiences (hashed email/phone/address uploaded from CRM); membership duration set to 540 days (platform maximum)
4 Ad personalisation Google tag ad_personalization consent parameter Not applicable (Basic Consent Mode; no tag fires without consent) Not applicable (Basic Consent Mode; no tag fires without consent) Configured via ad_personalization signal in Advanced Consent Mode; denied by default, granted only upon explicit user consent
5 Data retention (remarketing lists) Google Ads → Audience Manager → Membership duration Not applicable (no audiences) 30 days membership duration 540 days membership duration (platform maximum)
6 Processing location Google infrastructure / Controller-Controller Terms US (Google LLC); SCCs in place via Google's Controller-Controller Data Protection Terms; US government access via CLOUD Act US (Google LLC); SCCs in place; US government access via CLOUD Act US (Google LLC); SCCs in place; US government access via CLOUD Act

Configuration A — Lower Risk

Use this configuration when Google Ads is used solely for basic conversion measurement, without remarketing, audience building, or Enhanced Conversions. Basic Consent Mode is implemented: the Google tag is entirely blocked from loading until the user grants explicit consent. No data whatsoever is transmitted to Google prior to the user's consent interaction. Once consent is granted, the tag fires and standard GCLID-based conversion tracking is active, attributing conversions to the ad click that brought the user to the site. No remarketing audiences are built, and no hashed personal data is passed to Google. Processing occurs on Google's US infrastructure. As Google LLC is a US-based enterprise, data is subject to potential US government access under the CLOUD Act regardless of any technical routing. SCCs are included in Google's Controller-Controller Data Protection Terms. Google and the advertiser each act as Independent Controllers.

Configuration B — Medium Risk

Use this configuration when Google Ads is used for conversion tracking combined with Enhanced Conversions for Web and basic website visitor remarketing. Basic Consent Mode is implemented: the Google tag is entirely blocked from loading until the user grants explicit consent. No data is transmitted to Google prior to the user's consent interaction. Once consent is granted, the tag fires and standard GCLID-based conversion tracking is active. Enhanced Conversions for Web supplements this by capturing hashed first-party data — typically a customer's email address or phone number — directly from a website form at the point of conversion. The data is hashed using SHA-256 before transmission; Google uses the hash to match the conversion event against signed-in Google accounts, enabling attribution in privacy-restricted environments (e.g. Safari, Firefox, cross-device journeys) where the GCLID cookie may no longer be present. Website visitor remarketing lists are created with a 30-day membership duration, enabling ads to be shown to recent site visitors across Google's networks. No Customer Match upload is in use. Processing occurs on Google's US infrastructure; SCCs are included in Google's Controller-Controller Data Protection Terms, but as Google LLC is a US-based enterprise, data remains subject to potential US government access under the CLOUD Act regardless of any technical routing. Google and the advertiser each act as Independent Controllers.

Configuration C — Higher Risk

Use this configuration when Google Ads is deployed as a full-funnel advertising and measurement platform, combining Advanced Consent Mode v2, Enhanced Conversions, Customer Match audiences, and extended remarketing reach. Advanced Consent Mode v2 is implemented: the Google tag loads immediately with all consent signals (ad_storage, ad_user_data, ad_personalization, analytics_storage) set to denied by default. Even before consent is granted, anonymous, cookieless pings are sent to Google, communicating the consent state and key page-level events to enable conversion modelling — Google's machine-learning-based estimation of conversions that cannot be directly observed due to consent refusal. When consent is granted, the full tag fires. Enhanced Conversions for Web collects hashed email addresses or phone numbers from on-site form submissions; Enhanced Conversions for Leads additionally allows hashed CRM records to be uploaded offline to match leads to ad interactions. Customer Match audiences are built from hashed email addresses, phone numbers, or postal addresses uploaded from the advertiser's CRM, enabling ad targeting to known contacts across Google Search, Display, YouTube, and Gmail. Remarketing lists are set to the platform maximum of 540 days' membership duration. Data processing occurs on Google's US infrastructure; SCCs are in place via Google's Controller-Controller Terms, but US government access via the CLOUD Act applies in all cases. Google and the advertiser each act as Independent Controllers.


Step 2 — Mapping in the Consenter Manager
