Three ways people may discover information
People may discover information through traditional search results, answer-led experiences and generative AI tools. The labels are useful, but the bigger question is simpler: can your content be found, understood and trusted enough to help someone answer a real question?
SEO: make the page discoverable and relevant
SEO focuses on making pages easier to discover, understand and match with relevant searches. That means getting the fundamentals right: accessible pages, clear structure, useful content, sensible internal links and a strong match between the page and the search intent. Rankings are an outcome; relevance and usefulness are the foundation.
AEO: make the answer easy to extract
AEO focuses on making information easy to interpret as a direct answer. Clear headings, concise explanations and well-organised supporting detail help both people and answer-led systems understand what a page is saying. The goal is not to make content shallow; it is to make the answer obvious before adding the depth.
GEO: make the information worth referencing
GEO considers how content may be discovered, interpreted or referenced in generative AI experiences. Specific explanations, consistent terminology, original insight and transparent evidence can make a page more useful as reference material. No marketer can guarantee that a page will appear in an AI-generated response.
The overlap matters more than the acronyms
SEO helps a page become discoverable. AEO makes its answers easier to understand. GEO asks whether the information is clear and substantial enough to be useful in generative experiences. The practices overlap heavily, which is why a strong content foundation matters more than chasing separate checklists.
The opportunity is not to replace SEO. It is to create content that is easy to discover, easy to understand and useful enough to deserve attention.
What I would focus on
Start with real audience questions. Organise each page around a clear intent. Answer directly, then add context, examples and evidence. Keep the website technically accessible and easy to use. And when measuring performance, separate what you can observe from what you can only infer, especially in emerging AI discovery experiences.
