It is designed to help organisations adapt their tracking and advertising to current privacy requirements, while continuing to measure traffic, conversions and campaign performance in a more responsible way.<\/p>\n\n\n\n<p>In short, Consent mode v2 makes it possible to send signals to Google tools about what a user has consented to. This is especially important for advertising and analytics, where consent now plays a crucial role in determining what data can be collected and used.<\/p>\n\n\n\n<p>If you work with Google Analytics 4, Google Ads or a cookie banner solution, Consent mode v2 has become an important concept. It's not just about technology, but also about legislation, data quality and your organisation's ability to work effectively with digital marketing.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Why has Consent mode v2 become important?<\/h2>\n\n\n\n<p>The background to Consent mode v2 is an increasing focus on data protection in the EU and the rest of the world. Users need to have more control over what information is collected about them and how it is used for analytics and advertising.<\/p>\n\n\n\n<p>At the same time, many companies rely on data to optimise their online marketing. Without insights into traffic, purchases, leads and campaigns, it becomes harder to make good decisions. Consent mode v2 is Google's attempt to create a model where consent and data measurement can work together.<\/p>\n\n\n\n<p>For advertisers in the EU and EEA, it has also become particularly relevant because Google has tightened the requirements for how consent signals are collected and passed on. If set up incorrectly, it can affect targeting, measurement and ad performance.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Better alignment with GDPR and ePrivacy requirements<\/li><li>More correct handling of user consent in Google tools<\/li><li>Possibility of modelling data when full consent is not given<\/li><li>Greater importance of Google Ads, GA4 and conversion tracking<\/li><\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What is the difference between Consent mode and Consent mode v2?<\/h2>\n\n\n\n<p>The original version of Google Consent Mode provided the ability to adjust the behaviour of Google tags based on the user's choice of consent. Among other things, this meant that cookies and tracking could be restricted if the user declined certain categories.<\/p>\n\n\n\n<p>Consent mode v2 builds on this model, but introduces new consent signals that are particularly relevant for advertising. Whereas the first version primarily worked with analytics and advertising storage, v2 goes a step further and specifies more precisely how data can be used.<\/p>\n\n\n\n<p>It is precisely this extension that makes v2 important. It's not just about whether data can be stored, but also about whether user data can be used for advertising and personalisation purposes.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">The most important new signals in v2<\/h3>\n\n\n\n<p>Consent mode v2 introduces two additional parameters in particular: <em>ad_user_data<\/em> and <em>ad_personalisation<\/em>. They complement the existing signals and give Google clearer information about what the user has accepted.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>ad_storage<\/strong>: Whether advertising-related cookies may be stored<\/li><li><strong>analytics_storage<\/strong>: Whether analytics cookies need to be stored<\/li><li><strong>ad_user_data<\/strong>: Whether user data can be sent to Google for advertising purposes<\/li><li><strong>ad_personalisation<\/strong>: Whether data can be used for personalised ads<\/li><\/ul>\n\n\n\n<p>These signals help Google understand the limits of data processing. This makes consent management more granular and more in line with the requirements that many organisations face in practice.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">How does Consent mode v2 work in practice?<\/h2>\n\n\n\n<p>In practice, Consent mode v2 works by your website or app registering the user's consent choice via a CMP, a <a href=\"https:\/\/siite.dk\/en\/marketingordbog\/consent-management-platform\/\">Consent Management Platform<\/a> or cookie banner solution. When the user accepts or rejects different types of cookies, this choice is passed on to Google's tags.<\/p>\n\n\n\n<p>The Google tag then adapts its behaviour based on the consent signals it receives. If no consent has been given for advertising, certain types of storage and data processing will be restricted. If consent is given, the relevant features can be enabled.<\/p>\n\n\n\n<p>If the user does not give full consent, Google can in some cases use aggregated and modelled data to estimate conversions and user behaviour. This doesn't mean you get the same data quality as full consent, but it can reduce data loss in reporting.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Example of a typical flow<\/h3>\n\n\n\n<p>A typical process can look like this:<br><br>A user lands on your website and encounters your cookie banner. The user chooses to either accept, decline or customise their preferences. Consent mode v2 is then updated with the relevant signals that affect how Google Analytics and Google Ads may collect and use data.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The user visits the website<\/li><li>Cookie banner appears<\/li><li>The user makes a choice<\/li><li>Consent signals are sent to Google<\/li><li>Tags respond based on the user's choice<\/li><li>Data is collected fully, partially or modelled depending on the consent<\/li><\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Which Google tools are particularly affected?<\/h2>\n\n\n\n<p>Consent mode v2 is especially relevant for companies that use Google's advertising and analytics platforms. This includes Google Ads, Google Analytics 4 and <a href=\"https:\/\/siite.dk\/en\/marketingordbog\/google-tag-manager\/\">Google Tag Manager<\/a>.<\/p>\n\n\n\n<p>If you use conversion tracking in Google Ads, remarketing or audience data, proper consent setup is especially important. The same applies if you work with GA4 and want the most accurate reports possible without compromising privacy.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Google Ads<\/strong>: Conversion measurement, remarketing and advertising signals<\/li><li><strong>Google Analytics 4<\/strong>: Traffic measurement, incidents and user understanding<\/li><li><strong>Google <a href=\"https:\/\/siite.dk\/en\/marketingordbog\/tag\/\">Day<\/a> Manager<\/strong>: Tag management and consent logic<\/li><li><strong>Floodlight and other ad tools<\/strong>: Also depends on proper consent management<\/li><\/ul>\n\n\n\n<p>For many organisations, Consent mode v2 is therefore closely linked to the entire digital measurement infrastructure. An error in the consent setup can have consequences across multiple systems simultaneously.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What does Consent mode v2 mean for SEO and digital marketing?<\/h2>\n\n\n\n<p>Consent mode v2 is not directly an SEO feature, but it still matters for SEO and digital marketing. That's because good data is important when understanding user behaviour, landing pages, conversion rates and the overall interplay between organic traffic and paid channels.<\/p>\n\n\n\n<p>If you lose large amounts of data due to missing or incorrect consent setups, it becomes harder to analyse which pages are creating value. This can affect your work with both content and UX, <a href=\"https:\/\/siite.dk\/en\/marketingordbog\/cro\/\">CRO<\/a> and advertising.<\/p>\n\n\n\n<p>Conversely, a properly implemented Consent mode v2 can provide a better basis for decision-making. Even if not all users give consent, in some cases modelled data can help reduce blind spots in reporting.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Better basis for analysing user journeys<\/li><li>More reliable measurement of campaigns and conversions<\/li><li>Greater security for privacy and compliance<\/li><li>Better interaction between SEO, paid traffic and web analytics<\/li><\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Consent mode v2 and GDPR<\/h2>\n\n\n\n<p>Consent mode v2 is not the same as GDPR compliance in itself. It's important to understand. Google provides a technical solution to handle consent signals, but it doesn't absolve the company of responsibility for lawful processing of personal data.<\/p>\n\n\n\n<p>You still need to ensure that your cookie banner, consent solution, privacy policy and data processing are set up correctly. Consent mode v2 is therefore a tool, not a full legal guarantee.<\/p>\n\n\n\n<p>For Danish companies, this means that implementation should be seen as part of a broader compliance effort. This applies to technical setup, user information and documentation of consent.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">What you should be aware of<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Consent must be informed and voluntary<\/li><li>The user should be able to reject as easily as they can accept<\/li><li>Your CMP must be properly integrated with your tags<\/li><li>You should continuously test if the signals are being sent correctly<\/li><li>Privacy policy and cookie policy must reflect actual practice<\/li><\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">How do you implement Consent mode v2?<\/h2>\n\n\n\n<p>Implementing Consent mode v2 typically requires interaction between marketing, web development and possibly legal counselling. It's about both the technical setup and the way the consent is presented to the user.<\/p>\n\n\n\n<p>Many choose to implement the solution via Google Tag Manager and a CMP that supports Google's consent signals. This can make the setup more flexible and easier to maintain, especially if you work with multiple tags and platforms.<\/p>\n\n\n\n<p>The most important thing is that there is a connection between the user's choice and the actual data collection. If the user rejects advertising cookies, the system must not behave as if consent has been given.<\/p>\n\n\n\n<div style=\"height\":\"20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Typical steps in implementation<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Choose a CMP or cookie banner solution that supports Consent mode v2<\/li><li>Map which Google tags and scripts you use<\/li><li>Define default consent status before the user has selected<\/li><li>Configure consent signal updates according to user choice<\/li><li>Testing in browser, Tag Assistant and optionally GA4 debugging tools<\/li><li>Document the setup and review it regularly<\/li><\/ul>\n\n\n\n<p>It is recommended to test thoroughly on both desktop and mobile.<br><br>Even small errors in trigger logic, timing or tag configuration can lead to incorrect data processing or faulty measurements.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Advantages and limitations of Consent mode v2<\/h2>\n\n\n\n<p>Consent mode v2 has several clear benefits for organisations that want to reconcile privacy concerns with data-driven marketing. The biggest benefit is that you get a more structured and platform-customised way to communicate consent to Google.<\/p>\n\n\n\n<p>At the same time, it's important to be realistic. Consent mode v2 does not solve all problems. If a large proportion of users decline consent, you will still experience data loss. Modelled data can help, but it is not identical to observed data.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Benefits and advantages<\/strong>: Better compliance support, more precise management of data processing, improved modelling capabilities<\/li><li><strong>Limitations<\/strong>: Requires proper implementation, depends on user consent, not a legal solution in itself<\/li><\/ul>\n\n\n\n<p>For many organisations, Consent mode v2 is best seen as a necessary part of a modern tracking setup, but not the only solution to privacy and data quality challenges.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Typical mistakes companies make<\/h2>\n\n\n\n<p>Many companies think that Consent mode v2 is automatically in place just because they have a cookie banner. This is rarely enough. A CMP must be properly coupled with tags, triggers and consent signals, otherwise the solution will not work as intended.<\/p>\n\n\n\n<p>Another classic mistake is that the consent setup is only tested superficially. If tags fire too early or the default consent is set incorrectly, data may be collected contrary to the user's choice.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Lack of integration between CMP and Google tags<\/li><li>Incorrect default settings before consent<\/li><li>No ongoing testing or quality assurance<\/li><li>Unclear information to the user in the cookie banner<\/li><li>The assumption that technical setup alone ensures compliance<\/li><\/ul>\n\n\n\n<p>It's also a mistake to overlook the business implications. If measurement and consent are not linked, reports in both Google Ads and GA4 can be misleading and lead to poor marketing decisions.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Who should relate to Consent mode v2?<\/h2>\n\n\n\n<p>Consent mode v2 is relevant to far more than just techies. If your organisation uses Google Ads, Google Analytics 4 or other Google-related marketing tools, this is an area you should take seriously.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Marketing managers working with advertising and performance<\/li><li>SEO specialists who use analytics data to prioritise content and optimisation<\/li><li>Web developers and tag managers responsible for the technical implementation<\/li><li><a href=\"https:\/\/siite.dk\/en\/marketingordbog\/e-commerce\/\">E-commerce<\/a> managers who rely on accurate conversion measurement<\/li><li>Management who want a better understanding of risk, compliance and data quality<\/li><\/ul>\n\n\n\n<p>The more your business relies on data-driven decisions, the more important it becomes to understand what Consent mode v2 means and how it affects your systems.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion: What does Consent mode v2 mean for Danish businesses?<\/h2>\n\n\n\n<p>Consent mode v2 basically means that companies need to be more precise in their handling of user consent to Google. It's a technical and strategic update that has major implications for digital advertising, web analytics and data-driven marketing.<\/p>\n\n\n\n<p>For Danish businesses, the message is clear: If you want to continue using Google Ads and Google Analytics 4 effectively in an era of heightened privacy requirements, proper implementation of Consent mode v2 has become an essential part of your digital setup.<\/p>\n\n\n\n<p>It's not just about compliance, but also about ensuring a better and more reliable data base.<br><br>When consent, technology and business work together, you're stronger when it comes to analytics, advertising and digital growth.<\/p>","protected":false},"excerpt":{"rendered":"<p><!-- wp:paragraph --><\/p>\n<p>Consent mode v2 has become an important topic for companies working with Google Ads, GA4 and consent management.
