Your numbers never add up

GA4 says one thing, your CRM another, your sales a third. It's impossible to know what's true.

You're flying blind

Which channel really generates revenue? Which campaigns are burning your budget? You're not sure.

GDPR concerns you

Is your tracking compliant? You collect data, but are you sure you're following the law?

Result: marketing decisions based on false or incomplete data.

Frequently Asked Questions

FAQ

Answers to your most frequent questions.

Why a freelancer rather than an agency? +

A senior freelancer offers you a unique, expert contact directly involved in your project. No trainees, no billing for endless meetings, no turnover. You work with someone who has over 7 years of field experience and treats your data as if it were their own. More responsive, more flexible, and often more cost-effective than a traditional agency.

What is an Analytics Consultant? +

An analytics consultant structures your measurement setup from A to Z: auditing the existing setup, defining KPIs aligned with your business objectives, implementing tracking (client-side and server-side), building actionable dashboards, and ensuring GDPR/e-privacy compliance. They bridge the gap between marketing, product, and data to ensure every euro invested is traceable and every decision is based on reliable data.

What is server-side tracking? +

Server-side tracking involves collecting data on the server side rather than directly from the user's browser. This approach offers several advantages: better resistance to ad blockers, increased privacy, more reliable and accurate data. It is an advanced technical solution that becomes essential with increasing restrictions on third-party cookies and regulatory developments like GDPR.

How do you ensure compliance with data protection regulations? +

Compliance with data protection regulations is a priority in my approach. During tool configuration and technical implementation, I ensure strict adherence to current standards, including GDPR. This includes setting up appropriate consent mechanisms (Consent Mode v2), limiting data collection to strictly necessary data, and configuring tools to ensure the confidentiality and security of collected information.

What types of analytical and marketing tools do you generally recommend? +

The choice of tools depends on the specific needs of each company. I generally recommend a combination of tools including a web analytics solution (Google Analytics 4, Matomo), a Tag Management System like Google Tag Manager (client-side and server-side), visualization platforms (Looker Studio, Power BI), and suitable marketing automation tools. My expertise allows me to guide you towards the most relevant solutions for your business and to configure them optimally.

How can your services concretely improve my ROI? +

My services transform raw data into actionable insights. By creating dynamic dashboards and automated reporting, I enable you to clearly visualize the performance of your marketing actions. My support helps you interpret this data, identify optimization opportunities, and make informed strategic decisions. This results in better resource allocation, optimized marketing campaigns, and ultimately, a significant improvement in your return on investment.
