Google Consent Mode for Google Ads
Maintain Google Ads conversion tracking and remarketing while respecting user consent. UniConsent integrates with Google Consent Mode to recover conversion data through modeling when users decline consent.
Google Consent Mode for Google Ads
Google Ads uses Consent Mode to adjust conversion tracking and remarketing behavior based on user consent. When a user grants consent, Google Ads tags function as usual. When consent is denied, the tags adjust their behavior based on which consent types are denied.
When ad_storage is denied, Google Ads does not set advertising cookies. When ad_user_data is denied, user data is not sent to Google for advertising purposes. When ad_personalization is denied, remarketing audiences are not built for that user. In all these cases, consent-aware Google Ads tags send cookieless pings that feed Google's conversion modeling.
Since March 2024, Google requires Consent Mode for audience personalization and measurement features when targeting users in the EEA, UK, and Switzerland. Without Consent Mode, Google disables personalised advertising and conversion measurement for non-consented users in these regions.

How Consent Affects Google Ads Tags
When users deny consent for ad_storage, Google Ads tags do not set advertising cookies. Instead, they send cookieless pings that include basic conversion information without identifying the user. Google uses these pings to model the conversions that would have been observed with full consent.
When users deny ad_user_data, no user-level data is sent to Google for advertising. When ad_personalization is denied, the user is excluded from remarketing audiences and personalized ad targeting.
Advanced Consent Mode is required for conversion modeling. With Basic Consent Mode, Google Ads tags are blocked entirely when consent is denied, and no data is available for modeling.

Enhanced Conversions and Consent
Google Ads Enhanced Conversions sends hashed first-party data (email, phone, address) to improve conversion measurement. This feature requires ad_user_data consent. UniConsent ensures Enhanced Conversions data is only sent when the user has granted the appropriate consent.
Google Ads and Google Tag Gateway
If you use Google Tag Gateway to serve Google Ads tags from your first-party domain, UniConsent's Advanced Consent Mode ensures consent defaults are set before any GTG-served tag fires. See our Google Tag Gateway tutorial for setup details.
Frequently Asked Questions
Is Google Consent Mode required for Google Ads?
Since March 2024, Google requires Consent Mode for audience personalization and measurement features when targeting users in the EEA, UK, and Switzerland. Without it, Google disables personalised advertising and conversion measurement for non-consented users.
What happens to Google Ads when consent is denied?
When ad_storage is denied, Google Ads does not set advertising cookies. When ad_user_data is denied, user data is not sent to Google. When ad_personalization is denied, remarketing audiences are not built. In all cases, consent-aware tags send cookieless pings for conversion modeling.
What is conversion modeling for Google Ads?
When users deny consent, Google Ads tags send cookieless pings. Google uses these pings with machine learning to estimate conversions that would have been observed with full consent. This modeled data appears in your Google Ads reports alongside observed conversions. Advanced Consent Mode is required.
Does Consent Mode work with Enhanced Conversions?
Yes. Enhanced Conversions sends hashed first-party data (email, phone, address) to improve conversion measurement. This feature requires ad_user_data consent. UniConsent ensures Enhanced Conversions data is only sent when the user has granted consent.
Does Consent Mode work with Google Ads remarketing?
Yes. When ad_personalization is granted, remarketing tags work as usual. When denied, the user is excluded from remarketing audiences. Conversion modeling still works for denied users through cookieless pings.
Should I use Basic or Advanced Consent Mode for Google Ads?
Advanced Consent Mode is recommended for Google Ads. Basic mode blocks all tags when consent is denied, losing all measurement. Advanced mode sends cookieless pings that enable conversion modeling, recovering conversion data for non-consented users.
Can I use Google Tag Gateway with Google Ads?
Yes. Google Tag Gateway serves Google Ads tags from your first-party domain. UniConsent Advanced Consent Mode ensures consent defaults are set before any GTG-served tag fires.
How do I verify Consent Mode is working with Google Ads?
Use the UniConsent Consent Mode Scanner to verify consent signals are reaching your Google Ads tags. You can also check the developer console for consent-related warnings and review the implementation audit report in your UniConsent dashboard.
