What is the difference between SEO, AEO and GEO?
SEO helps pages rank in traditional search results. AEO structures content so answer engines and featured answers can use it directly. GEO makes content accurate, well-sourced and easy for generative AI systems to understand, cite and summarize.
What is Answer Engine Optimization (AEO)?
AEO is the practice of writing clear, direct answers to real questions, supported by headings, lists, tables and structured data, so answer engines and voice assistants can find and present them.
What is Generative Engine Optimization (GEO)?
GEO is the practice of making content easy for AI search tools to retrieve and cite. It relies on accurate facts, named sources, clear structure, author and brand trust signals, and consistent entity information.
Does SEO still matter in the age of AI search?
Yes. Crawlability, indexing, helpful content and site authority are still the foundation. AI search tools generally draw from content that search systems can already access and trust.
Does schema markup help AI search visibility?
Schema markup gives search systems explicit, machine-readable facts about your page, organization and authors. It supports understanding and eligibility for rich results, but it does not guarantee rankings or citations.
