Google has rolled out a significant Search upgrade built around Gemini 3.5 Flash and AI agents, signalling a sharp acceleration in how AI-generated answers will shape search results. At the same time, McKinsey's research frames AI search as the new front door to the internet, with roughly 50% of Google searches already showing AI summaries and over 75% expected by 2028.
Google's own GEO optimisation guidance remains consistent: pages must be indexed, crawlable, and technically eligible to appear in AI features. The emphasis is squarely on people-first content rather than shortcuts or "GEO hacks." Search Engine Land continues tracking AI search products across Google, Bing, ChatGPT, and Perplexity, with measurable evolution in how AI answer visibility is monitored across platforms.
What it means for you
The window to get your site cited by AI is narrowing—and it hinges on three non-negotiable basics. First, ensure full indexability and crawlability; any technical barriers will exclude you from AI-generated answers entirely. Second, focus ruthlessly on expertise and accuracy in your content; AI models reward depth and authority, not keyword density. Third, audit your existing content against what AI systems actually cite: if your pages aren't showing up in AI summaries from your competitors' searches, you have a visibility gap to close. With three-quarters of searches expected to include AI answers within two years, being absent from that layer is now a material business risk.
