I scale Amazon sales and profit
through advertising, listings and data

I manage Amazon Ads and develop product catalogues, listings and A+ Content. I connect advertising performance with sales, margin and conversion data to scale actions that generate real profit.

My proprietary AI-assisted Amazon Ads analytics system helps identify wasted spend, valuable search terms and campaigns ready to scale.

Issues & analytics system

More sales do not always mean more profit

I analyze Amazon Ads together with margin, conversion, price, availability and organic sales.

Most common issues

Wasted ad spend

Campaigns and targets generate cost without sufficient sales.

No control over TACoS and margin

Sales increase while advertising consumes too much of the business result.

Underused search terms

Valuable search terms are not moved into the right campaigns, while weak terms remain active.

Scaling the wrong products

Budget is allocated to products with weak conversion, poor listings or insufficient stock.

How my proprietary analytics system supports my work

  1. advertising and sales report analysis
  2. identification of spend without sales
  3. identification of valuable search terms
  4. bid, budget and negative targeting recommendations
  5. campaigns and products ready to scale

The system accelerates data analysis. I make the final decisions based on the product, margin, price, competition and business objective.

How I work

From audit to profitable scaling

A clear process, specific actions and regular reporting.

01

Audit & diagnosis

I review campaigns, reports, search terms, ACoS, TACoS, margin, listings, pricing and product availability.

02

Implementation & optimization

I introduce changes to campaign structure, budgets, bids, targeting, listings and catalogue data.

03

Reporting & scaling

Each week I provide KPIs, completed actions, conclusions and the next action plan. I scale what the data supports.
