What is AI SEO?

AI SEO (also called AEO - Answer Engine Optimization) is the practice of optimizing your website to be discovered, understood, and cited by AI assistants and large language models.

How is AI SEO different from traditional SEO?

Traditional SEO focuses on ranking in search engine results pages. AI SEO focuses on being cited in AI-generated responses, which requires clear content structure, authoritative information, and proper technical signals.
