Structural depth (GEO-SFE)
StructureImpact: High
What we measure
Heading hierarchy + nested structure depth — H1→H2→H3 nesting that mirrors a real outline.
Why it matters for AI citation
arXiv:2603.29979 shows a +17.3% citation lift for pages with measurable structural depth vs flat documents.
How to fix
Group your content under named H2 subsections. Use H3 for sub-points. Don't skip levels.
