methodology
The Ecommerce Grade (EG) Score is our 0–100 composite grade blending five signals per retailer: organic traffic strength (40%), domain authority (25%), cross-source market presence (20%), keyword breadth (10%), and year-over-year growth (5%). Scores are country-normalised so retailers within a market are directly comparable.
Inputs are compiled from public domain intelligence, organic traffic estimates, tech-stack signals, and legacy editorial rankings. Platform detection uses homepage HTML patterns.
