Frequently asked questions
Answers to your most frequently asked questions.
Why a freelancer rather than an agency? +
A senior freelancer offers you a single, expert, directly-involved contact on your project. No juniors in training, no billing for endless meetings, no turnover. You work with someone who has 7+ years of field experience and treats your data as if it were his 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 system from A to Z: audit of existing setup, definition of KPIs aligned with your business objectives, tracking implementation (client-side and server-side), construction of actionable dashboards, and GDPR/e-privacy compliance. They bridge marketing, product and data so that 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 respect, more reliable and accurate data. It's an advanced technical solution that is becoming 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 carefully ensure compliance with current standards, including GDPR. This includes implementing appropriate consent mechanisms (Consent Mode v2), limiting data collection to strictly necessary data, and configuring tools to guarantee the confidentiality and security of collected information.
What analytics and marketing tools do you generally recommend? +
The choice of tools depends on each company's specific needs. 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 appropriate marketing automation tools. My expertise allows me to guide you towards the most relevant solutions for your business.
How can your services concretely improve my ROI? +
My services transform raw data into actionable insights. By creating dynamic dashboards and automated reports, I allow 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 translates into better resource allocation, campaign optimization, and ultimately, a significant improvement in your return on investment.
