Dennis Yu profiles Igor Ivitskiy as a scientist who treats Google Ads accounts as experimental systems rather than collections of opinions. The article connects his academic background with large-scale campaign work and a method for finding hidden profit leaks.
Key takeaways
- Yu met Igor at Perry Marshall’s mastermind and says Igor sees profit leaks in Google Ads accounts “like heat vision.”
- Igor holds a PhD from Kyiv Polytechnic and has more than 200 research papers and 50 patents.
- He began running Google Ads experiments in 2006; one campaign generated more than $1 million in revenue in four days, and one account under his care had a $13 million monthly budget.
- In one client account, he showed that about 60% of the budget went to search terms that had never converted. His operating sequence is hypothesis → controlled test → numbers over opinions.
- The article’s 2026 updates include Igor’s #6 position among the Top 50 Most Influential PPC Experts 2026 after 1,306 votes, an upcoming SMX Advanced Europe talk in Berlin, and a profit-forensics corpus spanning 1,950 campaigns, 9.5 million queries, and 116,000 ads.
