AI Search Advertising: Impacts on Value, SEO, and Market Growth
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).
