Organisations should treat conversational AI search as an extension of digital discovery rather than a replacement for SEO. The same foundations—crawlability, indexability, useful content, clear site structure, internal linking and accurate information—remain necessary. GEO, or generative engine optimisation, is best used as a working term for improving the likelihood that owned and earned sources are retrieved, understood, cited and represented accurately in AI-generated answers. The most defensible actions are to clarify entities, answer important questions directly, publish evidence-rich canonical pages, make expertise and sources visible, keep volatile information current, strengthen third-party corroboration and measure patterns across a controlled query set. No organisation can guarantee inclusion, ranking or citation in an external AI system.
