Time-Sensitive Claims
Pricing, room availability, payment methods, product features and policies can change quickly. When those details matter, we prefer to verify them on the operator’s current site and record a review date.
What a Date Means
“Updated” means the editorial page was reviewed or materially revised on that date. It is not a guarantee that every third-party feature remained unchanged afterward.
Uncertainty
If we do not have reliable data for a numerical popularity, traffic, income or growth claim, we avoid publishing the number. Qualitative trend analysis is labeled as such.
