GEO, or generative engine optimization, does not mean writing pages for robots. It means organising useful information so that a reader and an answer engine can quickly understand the question, answer, evidence and context. Core SEO still matters because most answer engines rely on indexable, trustworthy pages.\n\nQ: What content format works? A: Lead each section with a direct answer, then give concise explanation and steps or a comparison where useful. Customer-like question headings, tables, lists and precise language help an answer be extracted without losing its meaning.\n\nQ: Are llms.txt or structured data enough? A: No. They are supporting signals. What improves citation readiness is specific experience, supportable claims, regular updates and copy that answers real questions better than generic repeated content.\n\nQ: What should be measured? A: Track search visibility, branded demand, enquiry quality and questions customers ask. The goal is for a customer to find a trustworthy answer and take the appropriate next step.
