How we rank: Ecommerce platforms
The Score (0–100) is a weighted sum of the factors below. Each factor is the weighted average of its metrics; each metric is calculated from one published fact. Missing facts score zero, and a service is ranked only when enough of its Score is backed by facts.
A service is ranked only when at least 70% of its Score is backed by verified facts.
Cost 45%
A free plan with no time limit on which you can sell, the lowest monthly price of a store plan on monthly billing ($0 scores 100, $50 or more scores 0; non-USD prices converted at the ECB rate, without VAT), the platform's extra fee on sales on the entry plan (0% scores 100, 3% or more scores 0) and the length of the free trial (14 days or more gets full credit). For open-source software the price is the platform's own price: hosting is paid separately.
