GPO’s State of Search & AI: September 2025

Discover the latest search & AI trends in September 2025. From antitrust shifts to AI traffic growth, see what’s reshaping digital visibility as we wrap up Q3.

Search only continues to evolve at a breakneck speed. Each month brings fresh developments that impact how people discover brands online. In this September update, we’ll explore the latest shifts and what they mean for marketers.

Recap of August’s State of Search & AI

In August, we saw Google push deeper into AI with the Web Guide and testing of ads in AI mode. Search behaviors began shifting toward longer, conversational queries while AI platforms started driving more meaningful traffic and conversions. We ended the month knowing that being mentioned in AI-generated results is just as important (if not more) for visibility as ranking in traditional SERPs.

What’s New in September?

From courtrooms to consumer sentiment, the forces shaping discovery are creating new challenges and opportunities for brands. Here’s a breakdown of the most important developments. 

Antitrust Ruling Has Potential to Reshape Search Market

A major court ruling fell short of breaking up Google but significantly altered the playing field. The decision bans exclusive contracts and requires Google to share its index with “qualified competitors.” This ruling opens the door for AI-driven search challengers, loosening Google’s historic grip on distribution

What this means for marketers: Visibility won’t be limited to Google. Brands must plan for competitors leveraging Google’s index to fuel new discovery experiences.

Generative Assistants Drive High-Intent Traffic

ChatGPT has emerged as a traffic powerhouse, reporting +94% year-over-year growth in visits. Even more compelling? Referral traffic from ChatGPT is showing higher conversion rates than Google. Answer-first discovery is proving to be a powerful driver of purchase-ready intent.

What this means for marketers: Optimizing for generative platforms is essential. Answer-based ecosystems deliver stronger intent and conversions than keyword searches.

AI Overviews Showcase Individual Business Reviews

AI Overviews now display individual business reviews pulled directly from Google Business Profiles. This change makes your review strategy more important than ever. A single customer comment can become the snippet that defines your brand in search.

What this means for marketers: Reputation management is no longer optional. Cultivating high-quality reviews can directly shape how your brand is represented in AI search. 

Consumers Are Skeptical of AI Summaries

Despite rapid adoption, not all users trust AI-generated answers. A Gartner study found that 53% of consumers distrust AI summaries and 61% want the option to disable them. Transparency and trust remain central to adoption.

What this means for marketers: Being included in AI search won’t be enough. Authoritative, transparent content builds the trust needed to stand out.

AI Platforms Rarely Agree on Recommendations

Fragmentation is here to stay. A study comparing ChatGPT, Google AI Overviews, and AI Mode found they only align on brand mentions in about 17% of queries. In other words, different AI platforms surface different answers.

What this means for marketers: Don’t rely on Google alone. Winning means being discoverable across multiple AI platforms.

September’s Big Takeaway? Search is Fracturing.

The definition of “winning” in search is changing. Search is no longer a single destination but an ecosystem of AI-driven experiences. The brands that adapt fastest will be the ones discovered first.

The path forward is clear:

  • Build authority across multiple AI and search ecosystems.
  • Treat review strategy as a core marketing lever.
  • Focus on trust and transparency in content.
  • Rethink KPIs. Visibility now means being “the answer” across fragmented platforms.

How are you preparing for a world where Google isn’t the only gatekeeper, reviews drive AI snippets, and ChatGPT delivers conversion-ready traffic? We’d love to hear how your brand is adapting.
