In this in-person episode of the Paid Search NYC podcast, we break down what the latest data from a 21 million–SERP study reveals about AI Overviews in Google Search - and why it’s already having a measurable impact on paid search performance, brand campaigns, and click behavior across retail, travel, finance, healthcare, and automotive, alongside a look at how ad fraud and brand impersonation are evolving in an AI-driven search world.
We’re joined by Phillip Thune (CEO, Adthena) and Shlomi Beer (CEO, Impersonally) to unpack large-scale SERP trends and examine the changing nature of ad fraud, phishing, and brand abuse as AI reshapes search experiences.
