Structural depth (GEO-SFE)

Three-level page architecture (macro/meso/micro) validated to lift citation rate +17.3%.

Structural depth (GEO-SFE), H2 coverage

Definition

Structural depth measures three orthogonal axes of page architecture: macro (heading hierarchy H1→H2→H3), meso (chunks per section: paragraphs and list items), and micro (visual emphasis density via bold/italic/code). GEO-SFE (arXiv:2603.29979) validated this as a +17.3% citation-rate lift across 6 engines.

Example

A page with one H1 and four H2 sections each containing 5+ paragraphs, with 1-5% of words emphasized via <strong>/<em>/<code>, passes all three axes.

How to optimize

Use H1→H2→H3 hierarchy. Target 5+ chunks per H2 section. Bold key terms at 1-5% density. VectorCite's structural-depth signal scores all three.
