Google Tag Manager specialist

As a tracking specialist, I work daily with Google Tag Manager (GTM) and server-side GTM (sGTM). I use these tools from Google as a powerful tool to set up your tracking in a smart, scalable and future-proof way.

GTM forms the basis of virtually every tracking infrastructure I deliver. Whether it's client-side tagging, server-side or complex offline conversion data streams with: I make sure everything works seamlessly together. That way we're not building a temporary solution, but a well-thought-out system that you can easily expand and customize.

Lester has set up tracking for several of my clients. He clearly knows what he's talking about, thinks through everything and makes sure everything works neatly and privacy-proof. No quick talk, just an honest guy who takes his job seriously and knows what he's doing. Highly recommended if you are looking for someone who really understands tracking and doesn't do half a job.

What does a tracking specialist do?

A tracking specialist makes sure you know exactly what works within your marketing and what doesn't. Not a standard analytics setup, but a smart infrastructure that measures the entire customer journey and links it to your advertising platforms.

As a tracking specialist, I help companies with:

Making the entire customer journey measurable (from website form, to accepted quote)
Collecting reliable data (client- and server-side)
Linking CRMs, forms and other systems
Returning valuable signals to Google, Meta and LinkedIn
Complying with privacy laws with Consent Mode and CMP integrations

The result? You no longer steer on assumptions, but on data that is correct. And that makes for better campaigns, higher returns and an edge in ad auctions.

Frequently Asked Questions

: Tracking is complex, especially if you want to do it right. Think about building a scalable tracking infrastructure, linking different systems and optimizing data streams for each ad platform.

Although I am often the first point of contact, within YesWeTrack I work with a specialized team of tracking experts and developers. This allows us to move faster, integrate better with your tools and build a solution that truly fits your situation.

The result? A tracking setup that lets you beat your competitors in ad auctions.
: To be sure. We regularly help companies clean up and restructure old GTM containers that dozens of marketers have worked on over the years. In short: we've seen the craziest things 😉

We can build on your existing setup, but if it is technically or strategically smarter to start over, we recommend a restructuring. Always with your goals and budget in mind.
: We almost always work with a fixed price per implementation, so you know exactly where you stand in advance. No surprises later, just a solution that fits your situation.

Do you still have specific work on back pay?

We charge an hourly rate of €115 for tracking work and €160 for strategic advice or consultancy.
