Domain Authority vs Page Optimization

We measured both dimensions from the same dataset — page-level HTML signals and domain-level authority metrics.

Domain Signals Are Dramatically Stronger

Authority Rank at d=1.075 is the single strongest signal. Referring subnets (d=0.513) are more than twice as predictive as referring domain count (d=0.235).

77% Domain, 23% Page

The logistic regression combining all 14 features shows domain factors account for 77.2% of predictive power. Page factors account for 22.9%.
