About me
I specialise in marketplace sales – mainly Amazon (DE/AT/CH and other EU markets) – and e-commerce. I manage the whole channel: listings, advertising, logistics and data.
What I can do for you: • Amazon Ads (PPC) – SP/SB/SD campaign structure, bid and budget optimisation, negative keywords, ACOS/TACOS control • Amazon listings – titles, bullet points, backend keywords, A+ briefs, keyword research with Brand Analytics • Content compliance – incl. food supplements on the German market • Amazon FBA – inventory planning, shipments, removal orders, reimbursement claims • Automation and reporting – Amazon SP-API, Advertising API, n8n, Google Sheets • SEO and Google Ads for online stores
I start with a data audit (reports, search terms, margin), set a measurable goal, implement changes and report results regularly.
