Proof of Usefulness Score

Category Standard

Project verified as the established travel aggregator KAYAK. While the real-world scale, utility, and traction are massive (Booking Holdings subsidiary, 6B+ queries), the specific submission provided is exceptionally low-quality, lacking detail and relying almost entirely on brand recognition. The score reflects the undeniable market dominance of the entity while penalizing the poor response quality.
