How Does Booking.com's Rating Actually Work?
Why Booking.com’s review system works differently from every other platform
Booking.com scores run 1–10, not the 1–5 stars used on most review platforms. A property’s displayed Guest Review Score is a weighted average of every individual guest score from the trailing 36 months, with more recent reviews counted more heavily than older ones — so a property’s score can keep moving even without a single new negative stay, simply as older high scores age out of the window.
Why Booking.com’s review system works differently from every other platform
Guests can also leave separate "subscores" for specific aspects of the stay — location, cleanliness, staff, comfort, facilities, value, and free WiFi — but these are submitted independently of the overall score, with no fixed formula linking one to the other. A guest can leave a 9 overall while scoring cleanliness lower, or vice versa.
The single most important structural fact: Booking.com reviews come exclusively from guests who booked and completed a stay (or arrived but didn’t stay) through Booking.com itself. Booking.com’s own guidelines put it directly — "The only way to leave a review is to first make a booking." Booking.com automatically emails the review invitation about 48 hours after check-out, and the guest has three months to submit it. There is no public review form, no way to review a property you didn’t book through the platform, and no route for a business, competitor, or third party to add a review from outside that closed loop.
Because reviews are guest-verified by design, Booking.com’s guidelines separately prohibit properties from posting on behalf of guests or offering incentives — discounts, upgrades, refunds, or anything else — in exchange for a review, and prohibit using reviews to attack a competitor’s rating.
What actually moves a Booking.com Guest Review Score
- A weighted average — every score from the trailing 36 months counts, but more recent reviews carry more weight than older ones.
- A closed, verified-stay system — only guests who booked and completed (or attempted) a stay through Booking.com can leave a review at all; there is no other way in.
- A 36-month rolling window — reviews stop counting toward the displayed score, and stop being shown, after 36 months (or after a change of property ownership).
- Response rate to the automatic post-stay invitation — Booking.com emails every eligible guest roughly 48 hours after check-out, so the property’s only lever is the quality of the stay that invitation follows.
- Guideline compliance — reviews Booking.com removes for violating its content standards (fake, off-topic, personal information, or a no-show reservation) don’t count toward the score.
