GEO builds on strong technical SEO foundations but adds layers specific to how large language models retrieve information. That means clear, well-structured content with explicit claims, cited data, and unambiguous entity definitions. Schema markup matters more, not less. Content needs to answer specific questions directly rather than burying the answer three paragraphs into a blog post. Authority signals, including consistent brand mentions, expert authorship, and trustworthy backlinks, influence whether an AI model treats your content as a reliable source worth citing.
