I'm Erika, an Amazon PPC Specialist. I've spent years managing Amazon Advertising accounts across a wide range of categories — Home & Kitchen, Baby Products, DIY, Supplements, and Apparel — handling 6- and 7-figure brands with budgets that range from lean to aggressive, across the US, UK, and EU marketplaces.
My approach is the same regardless of category or budget: audit the account down to the search term level, cut what's not working, harvest what already is, and build the structure around what the data actually says rather than assumptions. The Audit Tool on this site runs the same checks I'd run for a client.
