Generative Engine Optimisation (GEO) has replaced traditional SEO as the core strategy for AI visibility.
Instead of ranking blue links, GEO ensures brands appear within AI answers, summaries, and generative results.
It’s the discipline shaping how Google, ChatGPT, and Perplexity understand and present brand authority.
Today’s GEO specialists merge semantic SEO, AI data modelling, and entity engineering to help businesses appear everywhere users search — whether through traditional engines or generative systems.

Why GEO Now Matters More Than SEO
GEO focuses on how machines understand brands, not just where they rank.
SEO drives clicks. GEO drives citations, mentions, and trust signals that power AI-generated content.
The difference is strategic and financial — large brands now allocate separate budgets for GEO to manage visibility in the age of AI search.
