Why entrust me with your advertising budgets? 🎯
Former Account Strategist at Google, I have audited and supported over 1,000 advertiser accounts, from budgets of €500/month to large e-commerce brands at €50K/month, on issues related to leads, shopping, and pure performance.
Now a freelancer, I bring this "inside Google" perspective directly into the management of your campaigns: understanding bidding signals, anticipating algorithm updates, structuring for results.
On the Amazon Ads side 📦, I have supported e-commerce brands in their scaling on the marketplace, including a food sector brand that went from €10K to €200K in revenue in 12 months thanks to a structured Sponsored Products & Brands strategy and rigorous ACoS optimization. This is the main lever, but I also master the entire Amazon ecosystem: product page SEO, A+ content, Brand Store, marketplace compliance, to maximize the impact of every euro invested in advertising.
My areas of intervention:
- Google Ads (Search, Shopping, PMax): structuring, bidding, audit
- Amazon Ads: Sponsored Products, Brands & Display, ACoS optimization, scaling
- Meta Ads: acquisition and retargeting (strategic complement)
- Tracking & Data: conversion reconciliation, GA4/GTM setup
My methodology:
Audit first, then action. I analyze your campaign structure, identify quick wins and budget losses, then build a prioritized roadmap. Every decision is data-driven.
My goal is simple 🚀: to make every euro invested generate maximum revenue.
