Fit Score methodology

Our Fit Score reflects how reviewers rate a product’s performance against a set of features reviewers rate as most important. A higher score indicates the product is rated better in delivering what reviewers most care about.

  

If the Fit Score is not shown for a specific product, that only means there are currently not enough relevant data points to develop a meaningful score. It does not indicate that the product should be excluded from further evaluation. Best for Methodology
