I also worked hand in hand with production teams to fine-tune messaging and creative assets.

Alongside paid acquisition, I led a large organic growth (SEO) effort including content writing, performance analysis in Google Search Console and link building via RocketLinks.

Affiliate marketing expertise (Publisher)

As an entrepreneur and website publisher, I have built solid expertise in creating, optimizing and monetizing niche websites and online comparison sites. I manage these web projects end to end: from opportunity research (keyword research) to technical design, through content strategies and both organic (SEO) and paid (SEA/PPC) traffic acquisition. I actively work with the largest affiliate platforms and networks (Awin, Impact, Partnerstack, FinanceAds) to promote offers in ultra-competitive verticals (Finance, AI, SaaS software, Digital Marketing). This approach has given me deep command of affiliate tracking mechanics (tracked links, Postback URLs) and of optimizing the monetization and profitability of every visitor.

Acquisition strategies (B2B & B2C), copywriting and data challenges (cookieless)

My dual experience has taught me to adapt strategies to different sales cycles. In B2B, I deploy Account Based Marketing (ABM) and Lead Nurturing mechanics to address long cycles. In B2C (Retail & Automotive), I activate Drive-to-store, Web-to-store and pure e-commerce levers. Beyond the mathematical side of bid management, I pay particular attention to ad copywriting (Ad Copy, UGC, Storytelling, marketing angle testing) to maximize engagement rates. Finally, I operate in strict compliance with privacy regulations (GDPR, CNIL), adapting tracking architectures to the challenges of the cookieless era (first-party data collection, CMP / Consent Management Platform setup).

Performance management and key metrics (KPIs)

My data-driven approach relies on continuous analysis of the conversion funnel (TOFU, MOFU, BOFU) and core KPIs: optimizing CAC (Customer Acquisition Cost), CPL (Cost Per Lead), CPA, CPC, CPM and improving CTR (Click-Through Rate) through Quality Score. I excel at maximizing ROAS (up to 20 on affiliate campaigns) and overall ROI. I closely track Conversion Rate (CVR up to 10%), Average Order Value (AOV) and Customer Lifetime Value (LTV), analyze Churn Rate, and monitor recurring revenue (MRR/ARR).
