AI Search & GEO Optimisation — Visibility in the New Search Landscape
Search behaviour changed significantly in 2024 and 2025, and those changes are accelerating in 2026. Google’s AI Overviews now appear at the top of results for a growing proportion of queries. ChatGPT, Perplexity, Microsoft Copilot and other AI-powered tools are answering questions that used to drive clicks to websites — and they are citing specific brands and sources in those answers. Businesses cited in AI-generated answers gain significant visibility. Those that are not become invisible to a growing segment of their potential audience.
What Is GEO — and Why Does It Matter Now?
Generative Engine Optimisation (GEO) is the practice of structuring your content, authority signals and technical setup in ways that make your brand a preferred source for AI search systems. Where traditional SEO focuses on ranking in a list of ten blue links, GEO focuses on being cited in the synthesised answer that appears before those links — or in the AI tools that users are increasingly turning to instead of Google entirely.
The signals that influence AI citation overlap significantly with traditional SEO — strong E-E-A-T, comprehensive content coverage, high domain authority and well-structured structured data all contribute. But the weighting and application differ, and a site that ranks well in traditional search is not automatically well-positioned for AI citation. GEO requires its own strategic layer.
Expert SEO Online has been developing and refining GEO methodology since AI Overviews launched, integrating it into every SEO programme we run. We pair GEO strategy with strong technical SEO, comprehensive content strategy and authoritative link building — because all of these signals feed into AI citation decisions.
