Answer-first structureEXAMPLE

Pattern Summary

4 cited URLs

Every page opens with an H1 immediately followed by a 1–2 sentence summary paragraph defining the page's core value.
Opening paragraphs are concise (1–3 sentences), front-loading the core concept (e.g. 'GEO optimizes content for AI answer engines like ChatGPT and Perplexity') before any detail.
H1 text directly mirrors the page's subject keyword (e.g. 'What is GEO', 'GEO vs SEO'), minimising ambiguity for LLM retrieval.
