What is Consent Mode?
Consent Mode is a framework that allows websites and applications to adjust their data collection practices based on user consent. It acts as a bridge between data collection mechanisms and the user’s privacy preferences.
When a visitor interacts with a website’s consent banner, by accepting, customizing or rejecting cookies, Consent Mode ensures that tracking technologies, such as analytics and advertising scripts, adapt accordingly.
For example:
- If a user consents to tracking, tools can collect and process data as intended.
- If a user denies consent, tools are prevented from storing identifiable user data while still allowing aggregated or modeled data to be used where allowed.
- Users also can personalize their consent by selecting which types of data they’re comfortable sharing, such as allowing analytics but opting out of personalized ads.
This dynamic adjustment helps websites respect privacy laws while maintaining some level of insight into user behavior.

What’s Advanced Consent Mode?
Advanced Consent Mode, also referred to as Consent Mode v2, is the updated version of Google’s Consent Mode, designed to offer more granular control over how user data is handled.
While the original version (v1) focused on two core parameters:
analytics_storage(for analytics cookies)ad_storage(for advertising cookies)
Version 2 introduces two new consent parameters:
ad_user_data: Controls whether personal user data can be sent to Google for advertising purposes.ad_personalization: Determines if that data can be used to serve personalized ads.
These new parameters give advertisers a more detailed way to align with regional privacy requirements.
Timeline and Evolution of Consent Mode
Consent Mode became necessary due to increasing legal and regulatory pressure surrounding online data privacy.
Here’s how the landscape evolved:
- May 25, 2018 – The European Union implemented the General Data Protection Regulation (GDPR), requiring businesses to obtain explicit user consent before collecting or processing personal data.
- September 3, 2020 – Google introduced Consent Mode, allowing websites to adjust how Google’s tracking tags behave based on the consent.
- May 2, 2023 – The Digital Marketing Act (DMA) promotes fair competition and protects users in the digital market. It target major tech companies, known as gatekeepers (Alphabet = Google, Amazon, Apple, ByteDance, Meta, Microsoft), that wield significant influence over online platforms.
- November, 2023 – Google updates its Consent Mode (often called Consent Mode V2) expanding its functionality to better support regulatory compliance across different regions.
- March 6, 2024 – Google Consent Mode v2 became mandatory for all websites using Google services in the European Economic Area (EEA) and the UK.
- July 31, 2024 – Google Consent Mode v2 became mandatory in Switzerland.
- 2025 and Beyond – It is expected to be expanded to additional countries, including the United States.
Why Was Consent Mode Created?
The key reason for its development was to ensure compliance with privacy regulations while still allowing businesses to collect useful insights.
Here are the main drivers:
- Stricter Privacy Laws – GDPR, CCPA (California Consumer Privacy Act), and similar laws require websites to seek user consent before tracking.
- Growing Consumer Awareness – Users are becoming more conscious of how their data is collected and used.
- Adapting to a Cookieless Future – As third-party cookies face increasing restrictions, businesses need new ways to measure user behavior without intrusive tracking.
- Maintaining Data Insights – Even when users refuse consent, Consent Mode allows businesses to gather anonymized or modeled data to avoid complete data loss.
By implementing it, companies can continue running their marketing and analytics operations ethically and legally.
How Consent Mode Works
Consent Mode uses consent parameters to define what types of storage are allowed. The number and names of these parameters can differ based on the platform Consent Mode is used for.
When the website first loads, consent parameters are initially set to “denied“. If the user provides consent via the site’s consent banner, their values are updated to “granted“.
When a user provides full consent, tracking tags behave as normal. When a user denies consent, tags adjust their behavior:
- Instead of setting third-party cookies, the platform may use anonymous pings to estimate traffic.
- Instead of storing precise data, it may use conversion modeling to measure trends without violating privacy laws.
This approach ensures compliance while keeping marketing and analytics tools functional to a certain extent.
Key Benefits of Implementing Consent Mode
For website owners, adopting Consent Mode offers several advantages:
1. Legal Compliance
By aligning data collection with users’ consent choices, businesses avoid penalties associated with non-compliance under GDPR, CCPA, and similar laws. Learn more about the potential consequences in our article on Consent Mode fines.
2. Better User Trust
Consumers appreciate transparency. Websites that respect consent build trust, leading to improved user retention and engagement.
3. Retaining Some Data Insights
Even when users deny consent, businesses can still gather non-identifiable data to maintain measurement without breaching privacy laws.
4. Future-Proofing
As third-party cookies are increasingly restricted and regulations tighten, Consent Mode provides a sustainable solution for data collection and advertising.
Consent Mode Types
Consent Mode varies slightly depending on the platform it’s used for. Currently, there are two main types:
Google Consent Mode
Developed by Google, this version supports features like cookieless pings and modeled conversions. It works with tools such as Google Analytics, Google Ads, Google Tag Manager and Floodlight.
👉 We unpack Google Consent Mode in more detail here.
Microsoft Consent Mode
Consent Mode developed by Microsoft is newer and designed for Microsoft Advertising (formerly Bing Ads). It respects user consent preferences similarly to Google’s version.

How to Enable Consent Mode
The optimal approach to implementing Consent Mode varies based on your website’s infrastructure. Below is an overview of the most widely used methods.
1. Use a Consent Management Platform (CMP)
The easiest and most reliable way to implement Consent Mode is by integrating it with a Google-certified CMP, like Cookiebot, as it already supports it natively.
💡 Check if your CMP is Google-certified
It handles everything related to consent from banner design to consent collection and automatically passes consent signals, saving you time and reducing the risk of misconfiguration.

With Cookiebot, you have three main options for implementation:
- Via Google Tag Manager (GTM): You can configure Cookiebot directly in GTM without touching your website’s code. Ideal for marketers and non-developers.
👉 Here’s the step-by-step guide to setting up Cookiebot with GTM. - Using the WordPress plugin: If your website runs on WordPress, you can use the official Cookiebot plugin instead of implementing it via Google Tag Manager. This option doesn’t require any coding either.
👉 Follow this step-by-step guide to set up Cookiebot using WordPress plugin. - Manual implementation: This method involves adding the Cookiebot script directly into your website’s HTML. It gives you more control but requires technical knowledge. Recommended if you’re comfortable editing code or have a developer available.
Use Cookiebot CMP to collect user consent, stay compliant with GDPR and other global regulations, and ensure proper implementation of Consent Mode. Trusted by millions, available in 47+ languages, it’s the most popular solution for balancing privacy and performance. Easy to set up, fully customizable, and Google-certified.
2. Manual Implementation via GTM or gtag.js
If you’re not using a CMP, you can implement Consent Mode manually using Google Tag Manager or gtag.js following Google’s documentation.
You’ll need to define default consent settings, update them based on user choices, and ensure your tags behave accordingly.
This method gives you full control, but it requires more technical knowledge, making it easier to misconfigure if not done carefully.
How to Test Consent Mode
Testing Consent Mode implementation depends on the platform you’re using it for, Google or Microsoft. Each has its own setup, behavior, and verification tools.
