The HT Score is a composite ranking that considers 4 criteria groups and over a dozen variables to help hoteliers objectively compare hotel technology products. Guest Service has an HT Score of 0 and Amadeus has 26. Here is how the score is calculated.

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. Analyzes average satisfaction ratings (likelihood to recommend, ease of use, support, ROI), total review count relative to category peers, review recency (at least 20 reviews in the trailing 6 months), and share of voice across unique hotel clients to detect selection bias.

Partner Ecosystem

How highly do tech partners recommend this company?

Partner Recommendations, Integration Quantity, Integration Quality

Evaluates partner recommendations as expert votes of confidence, the number of verified integrations, and ecosystem quality — the average HT Scores of integration partners. Products with higher-quality integration ecosystems are more likely to deliver a connected tech stack.

Customer Centricity

How customer-centric is this organization?

Certified Support, Review Consistency, Profile Completeness

Assesses whether the company has earned HTR Customer Support Certification, maintains consistent review collection over time (an indicator of feedback-driven culture), and keeps product profiles complete with capabilities, screenshots, pricing, and features.

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.

Customer ratings and reviews are by far the most important factor in the HT Score algorithm. HTR does not accept payment for higher rankings. All reviews are verified — only hotel industry practitioners with confirmed affiliations can submit ratings. View full HT Score methodology →
