I’m Nabil, and for the past eleven years and counting, I’ve been immersed in the world of digital marketing, specifically focusing on the most critical, often-overlooked, yet highly impactful areas: conversion tracking, attribution, and advertising performance.

You’ve landed here because you’re likely facing the same challenge so many modern e-commerce businesses grapple with: your ad spend is increasing, your campaigns feel like they’re working, but your reporting is messy, your optimization is flawed, and you know you’re leaving significant revenue on the table due to data inaccuracies.

I’m here to solve that.

My journey began in Sweden, a nation known for its innovation and precision, and those very qualities have shaped my approach to marketing.

In an era where privacy changes, browser restrictions, and platform updates are constantly eroding the reliability of standard pixel-based tracking, generic solutions simply don’t cut it.

My expertise lies in architecting advanced, privacy-resilient data pipelines that don’t just collect data, but collect the right data, with the highest possible accuracy and reliability. Think of me as the chief architect of your digital growth foundation. I don’t just implement; I engineer.

The core of my work revolves around moving brands beyond basic pixel tracking and into the future of measurement.

This means deep, technical proficiency with the most robust tools available.

I specialize in the implementation and optimization of solutions like the Facebook Conversions API – the vital server-side partner to your pixel that maintains data integrity even as third-party cookies disappear.

Similarly, I leverage the power of the Google Ads API to ensure your Google campaigns are fed high-quality, server-validated conversion data, leading to superior Smart Bidding performance and a healthier Return on Ad Spend (ROAS).

But the stack goes deeper. To make all these complex systems work seamlessly, I heavily utilize Google Tag Manager (GTM), not just as a deployment tool, but as the control center for sophisticated event tagging, transformation, and routing.

And for those seeking truly robust, future-proof measurement, I am an advocate and expert in server-side tagging platforms like Stape.

Stape allows us to run Google Tag Manager in a server environment, giving us unparalleled control over data governance, speed, and reliability.

This server-side infrastructure is a game-changer for conversion accuracy, drastically improving how platforms like Meta (Facebook/Instagram), Google, and even niche analytics tools receive and process your customer’s journey data.

My goal for every client is simple: to help you achieve accurate attribution so you can confidently know which ads are actually driving your profit, and to empower better optimization so your ad platforms can finally learn and deliver the right message to the right person at the right time.

The final, beautiful outcome of this technical rigor is a more profitable and sustainable advertising performance.

No more guesswork. No more frustrating reporting discrepancies. Just clear, actionable, and reliable data that lights the path to growth.

If you’re ready to stop relying on fragile, outdated pixel methods and build a measurement foundation that can withstand the changes of the digital landscape, you’re in the right place.
