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.
