Dr Igor Ivitskiy is a mathematician who has spent twenty years applying mathematical modelling to advertising, and who now helps businesses make AI pay for itself.
Igor holds a PhD in mathematical modelling, is the author of more than 200 scientific publications and 50+ patents in mathematical modelling and engineering, and spent eight years as an Associate Professor at Igor Sikorsky Kyiv Polytechnic Institute. In 2006 he began applying the same methods to Google Ads. Since then he has managed more than $770 million in advertising spend across 50+ industries, audited over 2,000 advertising accounts and trained more than 4,000 business owners and marketers through his Google Ads school.
In 2026 The PPC Survey ranked him No. 6 among the 50 Most Influential PPC Experts in the world. At ADworld Experience 2024 his case won Best PPC Case in Europe (PPC Caesars Award). Perry Marshall, author of the Ultimate Guide to Google Ads, calls him "one of the leading Google Ads experts in the world"; Rich Schefren calls him "the #1 expert I know when it comes to advertising on Google".
Igor is the Founder and Chief Scientist of Doctor Ads, a UK consultancy that runs forensic audits of advertising portfolios and builds AI systems for marketing teams. Previously he was a Research Engineer at Lunio, working on real-time detection of click fraud.
Igor builds every talk on real advertising data. He has spoken at Hero Conf, ADworld Experience, International Search Summit, ecomTEAM and PPC.London, and is on the 2026 programme of SMX Advanced Europe. ADworld founder Gianpaolo Lorusso called him "the first speaker ever to gather only 5-star ratings". His talks cover how AI is changing the way customers find businesses, where advertising budgets quietly leak, and how small teams can use AI agents to do work that once required an agency.
His book on Google advertising became a #1 New Release on Amazon US and has been published in three languages.
