As AI-powered search capabilities from Google, Microsoft, and others continue to evolve, marketers are questioning the value of paid ads in an AI-dominated environment. Research indicates that paid ads face significant challenges, with a reported 34.5% lower average click-through rate (CTR) when AI Overviews are present. Moreover, there are instances where no ads accompany AI-generated answers, which affects visibility.

The paradox here is that while AI disrupts traditional ad visibility, it also offers new optimization tools that can improve conversions by up to 14%. Hybrid approaches that combine AI automation with human expertise show promise, with case studies indicating up to a 50% increase in return on ad spend (ROAS).

How AI Search Is Transforming the SERP

AI search engines have evolved to understand user intent and deliver direct answers within search results, diminishing the need for users to click through to websites. This shift dramatically alters the landscape for paid advertising.

“We’re witnessing the most significant transformation in search behavior since the introduction of mobile. AI search is fundamentally changing how users consume information and interact with paid advertising.” – Eric Siu, CEO of Single Grain

As AI-generated answers become more prevalent, the traditional paid search model faces significant challenges.
