My Approach

When managing paid advertising campaigns, I focus first and foremost on the business metrics that matter most—whether that means revenue, profitability, customer acquisition cost, lead quality, or another core objective.

My work is built around two key principles:

Hypothesis generation and experimentation

I continuously develop and test hypotheses aimed at improving campaign performance. Successful experiments help unlock meaningful growth, while inconclusive or unsuccessful tests reveal potential weaknesses, challenge assumptions, and provide insights that support better decisions in the future.

Continuous campaign optimization

Ongoing optimization is an essential part of my workflow. This includes reviewing and excluding irrelevant search terms, refining geographic targeting, improving keyword selection, adjusting bids and budgets, and identifying inefficient traffic segments.

This combination of structured experimentation and detailed campaign management allows me to continuously improve performance while keeping advertising activity aligned with broader business goals.

About the client

Overgear is a global e-commerce marketplace for digital gaming services, connecting players with professional service providers across multiple games and international markets. PPC activity supports multiple game ecosystems, service lines and purchase journeys, requiring disciplined segmentation, rapid experiment cycles and close efficiency control.

These results were achieved during my work at the PPC agency adgasm.io, where Overgear was my primary account. I was responsible for campaign strategy, execution, optimization, and performance reporting.

NDA naming policy

Game and project names are anonymized as project-*; direction names are anonymized as service*. Operational campaign suffixes—including _all, _retention, _test and _control—remain visible because they identify the test group, not the NDA entity.

Used Metrics

The case studies listed below contain data from GA4 and Google Ads related to the respective experiments.

For simplicity and consistency, several similar GA4 metrics—such as transactions, purchases, and total purchases—have been consolidated under the term “Transactions.”

The Google Ads “Cost / conv.” metric has also been renamed “CPA.”

“N/A” indicates that a metric cannot be calculated or is not applicable, while an em dash (—) indicates that no source value was provided.

Role: Product Manager

I initiated the development of a browser extension for faster negative keyword management in Google Ads and Microsoft Advertising.

The product was built together with my brother, Alex, who handled the technical development. I defined the concept and requirements, designed the core user flows and interface logic, and tested the extension in real PPC workflows.

The extension reduced the time required for routine search-term optimization and has attracted more than 600 PPC specialists worldwide.
