About

Sellertools.tech Agency helps brands already selling on Amazon manage advertising, improve product listings and resolve account issues. Clients work directly with Dawid Bocko, who has managed Amazon advertising since 2019. Our core service covers campaign strategy, search-term analysis, bid and budget optimisation, and clear reporting. Optional listing content, creative, catalogue fixes and Seller Central support are scoped separately. We begin with an account review, agree priorities and access, and provide clear updates and next steps.

The work began with product presentation and listing improvements: new photography, rewritten product copy and variations joined under parent listings. PPC targeting was then expanded to support the improved listings.

The original client portfolio reports one-year revenue growth of 1,601% and growth in units sold of 1,427%, from a low starting Amazon sales base. It also reports 9% average monthly TACOS. Growth figures are rounded; the 9% is the reported average monthly ratio, not a newly calculated annual weighted TACOS.

This is a selected prior case based on the original client portfolio. Raw account exports and exact comparator dates have not been independently rechecked. Listing and PPC changes were combined, so the contribution of each is not isolated. These results are not a guarantee of future performance.

STAT equipment: more units, a stronger organic sales share

The work combined advertising structure with product differentiation. PPC performance targets were set and campaigns were organised. Product changes included blue handles, branded packaging and a training insert. The original client portfolio reports Month 1 to Month 6 monthly units sold increasing 88.3%, organic sales share moving from 63% to 68%, and TACOS decreasing from 14% to 13%. Organic sales share is the share of total sales attributed to organic sales; TACOS is ad spend as a share of total sales. This selected prior case uses reported portfolio figures. The original account exports have not been independently rechecked. The 88.3% figure refers to monthly units, not revenue. PPC and product changes were combined, so neither contribution can be isolated. The Month 1 / Month 6 labels describe the source comparison; exact calendar dates are not asserted.

Provarm: more ad-attributed sales with lower ACOS

Amazon PPC management focused on reviewing account performance and making decisions around search terms, bids and budgets. For the selected Sponsored Products comparison, ad-attributed sales increased 64.7% while ad spend increased 53.7%. ACOS decreased from 19.22% to 17.93%: a 1.29 percentage-point reduction, or 6.7% relative improvement. The advertising figures compare 1–21 September 2026 with the same dates in 2025 across Belgium, Germany, Spain, France, Italy and the Netherlands. These are ad-attributed sales, not total account revenue. The lower strip is a separate Seller Central comparison: August 2026 vs August 2025 across those markets plus Sweden. Units ordered rose 60.71%; ordered product sales rose 54.06%. Sales include VAT, before fees; Sweden was converted to EUR. The strip recreates selected metrics and is not an original Amazon screenshot. These are selected account observations. They do not isolate the effects of PPC, the Seller Tools software, seasonality or other business changes. Confidential monetary amounts are omitted.
