I help e-commerce brands and retailers turn their ad spend into profitable, scalable growth through Google Ads, advanced GA4 analytics, and conversion rate optimization. What I bring to the table: → Google Ads strategy & management across Search, Shopping, and Performance Max — with a focus on ROAS-driven campaign structures and efficient budget allocation. → GA4 & e-commerce tracking setup — from event configuration to custom explorations, funnel analysis, and actionable reporting that connects data to business decisions. → CRO & landing page optimization — identifying friction points in the conversion journey and implementing data-backed improvements that move the needle. Key highlights: • Managed ad budgets across industries including pure-play e-commerce, retail, and luxury brands. • Delivered consistent improvements in ROAS and cost efficiency through rigorous campaign restructuring and audience segmentation. • Built end-to-end GA4 measurement frameworks for e-commerce clients, enabling smarter spend allocation. • Designed and delivered structured training programs on GA4 and Google Ads for marketing teams and product managers. I bring a hands-on, data-first approach — no fluff, no vanity metrics. Every recommendation is backed by the numbers.
