Consent Mode is a tool that can enhance the measurement of your Google Ads campaigns. Are you making the most of it?


Proper implementation of Consent Mode not only helps comply with privacy regulations but also significantly improves the ability to measure and understand campaign results, especially in a context where user consent is becoming increasingly complex.


What happens without Consent Mode?

Ad clicks that lack appropriate consent turn into lost data for platforms, leading to incomplete conversion reports. For instance, a campaign might appear less effective than it actually is, prompting decisions such as cutting budgets or changing strategies based on inaccurate data. This impacts the efficiency of advertising investment. With partial information, decisions are based on an incomplete reality.


How does Consent Mode help?

With Consent Mode, Google can model conversions that would otherwise remain invisible. This is achieved using statistical modelling techniques that analyse similar behavioural patterns to estimate how many conversions likely occurred, even when direct data is unavailable. Even without cookie consent, statistical modelling allows the estimation of conversions to provide a more realistic view.


The difference is clear: a 5% conversion rate without Consent Mode could rise to 5.9% with conversion modelling enabled, representing an 18% improvement in reporting accuracy.



Implementation is key

Ensuring that Consent Mode is properly configured is crucial. It’s not enough to rely on just any CMP (Consent Management Platform). A Google-certified CMP, such as Cookiebot, can automate this process, simplifying management and ensuring compliance with regulations.


In my experience, there are several ways to check if a website has implemented Consent Mode correctly. Some useful tools include Consent Mode Inspector and Google Tag Assistant (the latter is used to verify proper implementation of Google Tag Manager and Google Analytics on the site). You can even perform a more in-depth analysis through Google parameters, where "gcs: G111" would indicate that Google recognises Consent Mode.


Do you already have Consent Mode implemented on your website?




One might wonder, how is customizing reports in Google Analytics 4 (GA4) useful for digital marketing professionals? The answer is grounded in the ability of GA4’s advanced features to enhance our data analysis, leading to more informed decision-making.


GA4 represents a significant shift from Universal Analytics. It introduces user-centric metrics like 'Engaged Sessions' and 'Engaged Users.' This evolution is critical because it provides a more nuanced understanding of user interactions, which is key to developing effective marketing strategies.


Engaged means “active or interacting with” — users that had some interaction with your site, not limited to navigation.


Customizing reports in GA4 is not just an optional feature; it's a necessity for precise data analysis. Tailored reports allow us to align the vast amount of data with specific business objectives, thus converting raw data into actionable insights for strategic decisions.


The capacity to modify and enhance reports in GA4 should be viewed as an opportunity for deeper data exploration. By customizing reports, we can focus on metrics and dimensions that are directly relevant to our specific business needs, ensuring that our analytics are both comprehensive and pertinent.


In short, proficiency in GA4’s customization capabilities is essential for turning analytics into a strategic tool. Sharing our experiences and insights, may contribute to the community of professionals who try to utilize data effectively.





Are you ready for the future of digital marketing in a world without third-party cookies? The landscape is changing rapidly, and staying up to date on this subject is crucial. Google's decision to phase out third-party cookies presents a significant challenge for us as digital marketing professionals: adapting our strategies and focusing on collecting our own data in an ethical and transparent manner.

But what does this really mean for you as a marketing professional? This transition offers a fantastic opportunity to strengthen the relationship with your clients through more personalized and direct data collection. Google's 'Privacy Sandbox' encourages innovation in our advertising campaigns, keeping user privacy as a priority.

Facing uncertainty about the actual effectiveness of these strategies, how can we be sure of their impact? Exploring alternatives like contextual advertising and cohort-based targeting opens new doors, allowing us to adapt to emerging regulations and changing expectations of privacy. Consent management becomes a crucial aspect, highlighting transparency and building trust with the audience.

In this new environment, how can we ensure we are making the right decisions? Adaptability is the most important ingredient.

This change represents a unique opportunity to redefine how we interact with our customers and how we analyse and value their data. It invites us to be more creative and more aligned with the needs and desires of our audience.
