What's the difference between SEO and GEO?

SEO (Search Engine Optimisation) focuses on improving visibility within traditional search engine results. GEO (Generative Engine Optimisation) builds on those same principles by helping AI-powered platforms such as ChatGPT, Google AI Overviews, Gemini and Perplexity understand, cite and recommend your organisation. In practice, strong SEO remains the foundation for effective GEO.

Is GEO replacing SEO?

No. Traditional search remains hugely important and continues to generate the majority of website traffic for most organisations. Rather than replacing SEO, GEO complements it by considering how AI-powered search tools discover, interpret and present information.

Which term should my organisation use: GEO, AEO or LLMO?

For most organisations, the terminology matters far less than the underlying work. GEO is currently emerging as the broadest and most widely recognised term, but the optimisation techniques behind GEO, AEO and LLMO overlap significantly. Whichever term you choose, consistency and good practice are more important than the acronym itself.

We help organisations prepare their websites for AI-assisted search by improving content structure, technical foundations, structured data, authority signals and overall website quality.
