GEO vs SEO: What's the Difference and Why It Matters in 2026

Every few years a new acronym appears in the digital marketing world. With GEO, it's not a revolution that makes everything else obsolete, nor just a rebrand. It's genuinely new.

What Traditional SEO Is

Search Engine Optimisation is the practice of improving a website's visibility in search engine results pages. This framework has worked well for 25 years. It still works. But it is no longer the complete picture.

What GEO Is

Generative Engine Optimisation is the practice of optimising content and digital presence to be cited, referenced or summarised by AI-powered search systems including Google AI Overviews, ChatGPT browsing, Perplexity and Bing Copilot.

The Four Layers: SXO, AIO, GEO and AEO

SXO combines traditional SEO with user experience. AIO makes content legible and extractable for AI systems. GEO builds enough authority that AI systems choose to cite your business. AEO crafts content that directly answers specific high-intent questions.

Practical First Steps

Start with a full audit of where you currently stand on all four layers. Most businesses have done reasonable work on the SXO layer and almost nothing on AIO, GEO and AEO. That's where the opportunity is in 2026.
