Optimal Structure
The content structure for maximum AI citation: A 35-50 word direct answer immediately after the H1 heading. Body content in 130-167 word self-contained passages under clear H2/H3 headings. A specific statistic every 150-200 words. Authoritative citations throughout. Comprehensive schema markup.
Answer Islands
The Answer Island concept describes semantically independent units that are completely understandable without surrounding context. Passages that rely on "as mentioned above" or contextual references lose clarity when AI systems extract them.
