What Is GEO (Generative Engine Optimization) and How to Get Your Brand Recommended by ChatGPT and Gemini

Search and information-discovery behaviour online is going through its most radical transformation since the rise of modern search engines. While traditional Google search still plays a key role, millions of users, business decision-makers and consumers have grown used to AI-powered assistants and answer engines — like ChatGPT, Google Gemini, Perplexity and Claude — to get direct recommendations, comparative summaries and vendor suggestions.

This shift in consumer behaviour has given rise to a new, fundamental discipline in digital marketing: GEO (Generative Engine Optimization) — the strategic optimization of platforms and digital data to ensure a business is accurately cited, recommended and summarized by generative language models when users search for solutions in its sector.

The Structural Difference Between Traditional SEO and GEO

In traditional SEO, a brand's goal is to rank a specific URL at the top of Google's results page (the SERPs) for an individual keyword. The user scans the list of links, picks one, and navigates to the website.

In GEO, the focus shifts from the isolated keyword to the concept of entity and synthetic authority. The user asks the AI an open, complex question (for example: "What are the best digital marketing agencies in Lisbon that specialize in B2B and focus on ROI?"). The language model processes multiple authority signals, cross-references real-time information sources, and synthesizes a direct answer — explicitly recommending two or three companies with contextual justification.

Making sure your business gets recommended by AI assistants and answer engines is the new frontier of digital visibility. At Nexus, we build these techniques directly into our Nexo Method. Talk to the Nexus team to get your brand ready for the GEO ecosystem.
