From the user’s perspective, the most direct experience of Consent Mode is that when entering the website, you will receive a pop-up window, also called a cookie banner. The user will be asked here whether he agrees to the collection of relevant data by the website, and the user can make the appropriate choice. When the website backend or other platforms receive relevant instructions, they will perform corresponding processing, such as whether to collect user data, what data to collect from users, etc. The picture below is the cookie banner of Amazon’s German website. Currently, when we visit the United States and other non-EU sites, we will not receive relevant reminders.
Introduction to Consent Mode
What is Consent Mode?
Consent Mode is a privacy protection mechanism developed by Google that allows website and application developers to dynamically adjust the behavior of Google code and third-party tracking tools based on users’ consent to data collection.
There are two opinion solicitation modes, one is the basic opinion solicitation mode and the other is the advanced opinion solicitation mode. Their differences are shown in the table below. It is recommended that you set up the advanced opinion solicitation mode. This article also introduces the setting of this opinion solicitation mode.
| Function | Basic Consent Mode | Advanced Consent Mode |
| Code loading | Blocked until the user interacts with the consent banner. | Loads it and sets the default consent to Deny (unless configured otherwise). |
| Data transfer | No data is sent without the user’s consent (including default consent). | If the user chooses to decline, a consent and cookie-free ping is sent. If the user chooses to agree, the cookie is written and all measurement data is sent. |
| Consent | Set after user interaction. | Set default consent to Deny (unless configured otherwise); update based on user consent results. |
| Code behavior after user interaction | Load and execute the consent mode API only after the user has given their consent. | Adjust code behavior based on user input. |
| Estimate conversions based on model | Regular model (less detailed modeling). | Advertiser-specific models (more detailed modeling). |
Reasons for implementing Consent Mode
The main reason for the introduction of the Consent Mode is to comply with the requirements of relevant laws and regulations, mainly the two regulations GDPR (General Data Protection Regulation, General Data Protection Regulation) and DMA (Digital Markets Act, called Digital Act), mainly the legal requirements in the European Union. Other countries and regions also have relevant regulations on privacy and data security. Of course, the current opinion solicitation model is mainly to cope with the relevant regulations of the European Union. For other reasons, you can also refer to the table.
| Reasons for implementation | Specific instructions |
| Legal Compliance | Meet GDPR, DMA and other regulatory requirements to ensure valid consent is obtained before storing/sharing user data |
| Data Continuity | Alleviate data disconnection problems caused by user rejection through signaling and machine learning modeling |
| Unified management | Standardize the interaction between CMP (Consent Management Platform) and tracking code to simplify multi-platform compliance management |
| Advertising optimization | In advanced mode, the conversion model built based on desensitization signals is more than 30% more accurate than the basic mode. |
