Criteria Group Weight What It Measures
Customer Ratings & Reviews

How highly do users recommend this product?

Ratings Score, Review Volume, Share of Voice, Review Depth, Review Recency, Success Stories

The most heavily weighted factor.

Customer Centricity

How customer-centric is this organization?

Certified Support, Review Consistency, Profile Completeness

Reach, Staying Power & Resources

How extensive is this company's reach and resourcing?

Geographic Reach, Staying Power, Company Resources, Trending Score

Measures global presence (countries and regions served), years in business as a stability proxy, team headcount as a resource proxy, and a trending score based on trailing-twelve-month buyer inquiries, reviews, partner recommendations, and press activity.
