GEO is the discipline of making your entire digital presence legible to AI systems. That means three concrete things.
First, structured data. Schema.org markup tells AI crawlers who you are, what you do, and why you are qualified. Without it, AI systems have to guess. With it, you provide direct, unambiguous information. Your name, your expertise, your credentials, your service area, all structured in a format machines can read without interpretation.
Second, an llms.txt file. This is a direct instruction layer for AI crawlers, similar to robots.txt for traditional search bots. It tells AI systems which content to prioritize, how to describe your business, and what context matters. Most business websites do not have one. That is a gap that costs visibility.
Third, topical authority. AI systems assess whether you have consistent, deep coverage of your domain. One strong article on a topic is not enough. A coherent body of content that covers your expertise from multiple angles, consistently attributed to you, is what builds the entity recognition that GEO requires.
