Generative Engine Optimisation (GEO) is transforming how brands appear in AI-driven search.

While SEO once focused on ranking blue links, GEO focuses on appearing inside AI answers, summaries, and discovery systems.

It’s the next phase of search visibility. The difference between SEO and GEO is strategic and financial.

Businesses now separate budgets for both because GEO demands deeper control of entities, context, and brand data.

The best GEO experts combine semantic SEO precision, brand engineering, and AI alignment to shape how generative systems interpret brands.

Understanding the Shift

What is the difference between SEO and GEO?
SEO ranks webpages. GEO ensures those pages are referenced inside AI answers.
SEO drives clicks. GEO drives visibility without clicks through citations and summaries.

How does GEO compare to AEO?
AEO targets Google’s featured snippets. GEO feeds large language models with structured, factual data to maintain presence across AI systems.

What is LLMO?
LLMO (Large Language Model Optimisation) focuses on teaching AI models to interpret and cite brands correctly through consistent semantics and entity structure.

Can SEO, AEO, and GEO work together?
Yes. SEO builds authority. AEO delivers instant answers. GEO extends that authority into AI-driven ecosystems. Together, they create omnipresent visibility.

Why is GEO critical for 2026?
Google, Bing, and AI platforms now prioritise generative results.
Brands not optimised for GEO risk disappearing from user journeys.
Structured, factual, and semantic content ensures brands remain visible inside AI Overviews, not just SERPs.

Should businesses hire GEO experts?
Yes. GEO experts future-proof brand visibility by aligning content, data, and entities with AI systems that power generative search.

Are GEO experts more expensive than SEOs?
Usually, yes. GEO requires semantic modelling, entity structuring, and AI interpretation, demanding greater technical and strategic depth.

Should SEOs reposition as GEO specialists?
Only if they understand entity optimisation and AI retrieval. Rebranding without genuine knowledge creates false authority. True GEOs combine semantic skill and AI insight.

Do large enterprises separate SEO and GEO budgets?
Yes. SEO handles traditional visibility. GEO manages AI discoverability and reputation control.
Agencies that can deliver both now access dual budgets and dominate both blue-link and generative search.
