Generative Engine Optimization (GEO) is revolutionizing documentation by increasing the need for content to be AI-friendly, as large language model (LLM) traffic is expected to rise significantly by the end of 2025. This shift, highlighted by platforms like Mintlify, necessitates the creation of AI-readable documentation formats such as llms.txt files and markdown versions, which facilitate AI navigation and comprehension. Traditional SEO practices, while still essential, are becoming foundational rather than sufficient as users increasingly rely on AI tools for direct, contextual answers rather than navigating documentation hierarchies or using search functions. This evolution is prompting companies to adapt their documentation to support AI-driven information retrieval, ensuring that their content is discoverable and useful in this changing landscape. Mintlify illustrates the proactive role that documentation can play in the ecosystem by implementing features that make content accessible to AI, and emphasizes the importance of agility in keeping up with technological advancements in information consumption.
