Pages engineered with a 45–55 word definitional answer lead, at least 1 quantitative statistic every 150 words, structured HTML comparison tables, valid Entity JSON-LD, and an accessible /llms.txt file achieve a 3.4x higher citation probability across ChatGPT Search, Perplexity, and Google AI Overviews compared to unstructured blog posts.
Methodology Note: 2026 structural analysis of RAG (Retrieval-Augmented Generation) citation signals across ChatGPT Search, Perplexity AI, Google AI Overviews, Claude, and Copilot.
