What does a tracking project involve?

It depends on the site's starting point. It usually means implementing tags in a Tag Management System such as Google Tag Manager, to capture specific actions, called events, and send them as data to a third-party platform (GA4, Google Ads, etc.), so you know what is really happening on your website. The number of tags and how they are configured depend on the analysis you want to carry out.

Do I work on-site or remotely?

Remotely, wherever you are: video calls, delegated access and regular check-ins are enough to run a project end to end. On-site work remains possible in Paris and in the South of France, especially for scoping workshops and training sessions.

Q: Does implementing GTM and GA4 take long?

Allow a few days for a brochure site, and two to four weeks for an e-commerce site or a complex funnel. The timeline mainly depends on the number of tags, technical access and testing time. I give you a precise estimate in the action plan, and support can continue for several months if you want your measurement to evolve.

Q: How much does a tracking project cost?

The price depends on the scope. A core project — GTM installation, GA4 configuration and a tracking plan — starts at €1,200. Depending on your needs, you can add e-commerce tracking, server-side tracking, Google Ads integration or dashboards. The quote is fixed and drawn up after the free pre-audit: no surprises along the way.

Q: What is the difference between a freelancer and an agency?

You deal directly with the person working on your account, with no intermediary and no change of contact. Decisions take hours rather than several meetings, and the price does not carry agency overheads. In return, I work on a focused scope — measurement and analysis — with a network of partners when a project needs other skills.

I build reliable data architectures so you can make better decisions and improve your marketing performance.

Questions you are probably asking

What does a web tracking project involve?

A web tracking project means installing, configuring and testing a tag manager, analytics tools and a CMP, which collect, filter and measure data about a site's users (e-commerce or lead generation).

Does implementing GTM and GA4 take long?

For the audit, tag manager and analytics setup, ten tags and the tracking plan on a small lead-generation site, allow 3 to 5 days. For an e-commerce site with more than 50 pages, allow 4 to 5 weeks.

How much does a tracking project cost?

It depends on the size of your site. A tool audit starts at 350 €, 450 € for the site audit, 700 € for tag implementation. Monthly support with recommendations is also available, at 500 € per month.

What is the difference between a freelancer and an agency?

With a freelancer, you get tailored support with no intermediary, from audit to follow-up. Communication is more direct and turnaround times are shorter.

Do you work on-site or remotely?

I work remotely across France, Belgium and French-speaking Switzerland, and on-site in the Marseille area, depending on your needs.
