How your property's rating is calculated on Booking.com, Google, Tripadvisor and Airbnb (2026)

Updated: 10 November 2026

An 8.7 on Booking.com, a 4.6 on Google, 4.5 bubbles on Tripadvisor and a 4.92 on Airbnb are not calculated the same way and don't change at the same pace. This guide sums up what each platform's official help says (checked on 10 November 2026): which scale they use, which reviews count and for how long, what you can legitimately do to improve and what a penalty can cost you. Whatever we could not confirm in an official source is marked «not confirmed».

The short answer

The essentials:

Booking.com: a 1-10 score given by the guest; recent reviews weigh more («weighted review system») and may stop being shown after 36 months.
Google: the average of all ratings published on Google, 1 to 5 stars; it may take up to 2 weeks to update. Weighting: not mentioned (not confirmed).
Tripadvisor: 1-5 bubbles; the Popularity Ranking combines quality, recency and quantity of reviews and is recalculated daily.
Airbnb: an overall rating and 6 categories from 1 to 5; the overall rating is not the average of the categories. Guest favorites requires, among other things, 5 reviews in 4 years.
On no platform can the property delete a negative review: it can only reply or ask for a review if it breaks the rules.
How these scores weigh in AI assistants (ChatGPT, Gemini, Claude…): no official source, not confirmed.

Booking.com: 1-10 score and subscores

According to «How we work», the Partner Hub and Booking.com's review standards:

Only people who booked through Booking.com can review (also if they arrived but didn't stay). The invitation email goes out about 48 hours after check-out and guests have 3 months to write.
The guest picks an overall score from 1 to 10. Separately they can rate cleanliness, comfort, value, facilities, location and staff (sometimes Wi-Fi or breakfast): those subscores don't count towards the overall score.
Booking.com says it uses a weighted review system: the more recent the review, the bigger its impact on the score. The partner help describes it as an average of the scores; exact weights: not confirmed.
Reviews may stop being shown after 36 months or after a change of ownership, and the score is recalculated with those still online.
The score shows from the first review. The «Top reviewed» sort also takes the number of reviews into account.
Trade press (Hospitality Net, 6-1-2026): the greater weight of recent reviews was announced in December 2024 and applied in early 2025.

Google: 1 to 5 stars

According to Google Business Profile and Google Travel help:

The score is the average of all ratings published on Google for that place, from 1 to 5 stars.
The help page mentions no weighting by age: not confirmed.
After a new review, the score may take up to 2 weeks to update; the review itself can take a few days to appear because it is checked.
In hotel search, the average shown only includes Google users; licensed third-party reviews are shown separately and Google doesn't verify them.
Travellers can filter by user rating and sort by highest rating; relevance ranking uses «dozens of factors», including ratings and reviews.

Tripadvisor: bubbles and Popularity Ranking

According to Tripadvisor for Business:

Bubbles go from 1 to 5 (3 is average, 5 excellent) and come from users' overall ratings. Exact formula and half bubbles: not confirmed.
The Popularity Ranking (your position in the destination) is based on the quality, recency and quantity of reviews, and their consistency over time.
Older reviews stay visible but count less towards your position than new ones.
It is recalculated daily. It is relative: you can drop because nearby properties get good reviews.
Sub-ratings (cleanliness, service…), management responses and any commercial relationship with Tripadvisor don't count.
Fraud is penalised with a lower position and can lead to a visible red alert.

Airbnb: stars, categories and Guest favorites

According to Airbnb's Help Center and Resource Center:

Guests give an overall rating and one for 6 categories (check-in, cleanliness, accuracy, communication, location and value), all from 1 to 5.
The overall rating is not the average of the categories. The overall average appears in search once there are 3 ratings.
Host and guest have 14 days after checkout; reviews are published when both have written or when the window ends.
Guest favorites is based on overall rating, review feedback, communication, category ratings, host cancellation rate, review removal rate and quality incidents; minimum 5 reviews in the past 4 years, at least 1 in the past 2.
The Resource Center mentions averages above 4.9 and high marks in all 6 categories; Superhost requires at least 4.8. Listings are evaluated daily. Exact formula: not confirmed.

How long the score takes to change

What the official sources say:

Google: up to 2 weeks after a new review.
Tripadvisor: the Popularity Ranking is recalculated daily.
Airbnb: Guest favorites is evaluated daily; reviews are published at the latest 14 days after checkout.
Booking.com: reviews arrive up to 3 months after check-out and recent ones weigh more; exact time to see the change: not confirmed.
Everywhere, a single review barely moves a score built on many: the realistic path is a steady flow of new reviews.

What you can legitimately do

Practices the platforms themselves allow or recommend:

Ask every guest for a review, not only happy ones: Tripadvisor explicitly encourages it (Review Express) and Booking.com already emails every guest.
Reply to reviews, good and bad: Booking.com lets the property respond. On Tripadvisor replies don't move your position, but travellers read them.
Fix what keeps coming up in complaints (cleaning, noise, Wi-Fi, check-in) and make the listing match reality: on Airbnb accuracy is a category of its own.
Report or request a review of reviews that break the rules (fake, from someone who didn't stay, offensive): the platform decides.

What you must not do

Prohibited under the official rules:

Offer incentives in exchange for reviews (discounts, upgrades, gifts, money): prohibited by Booking.com, Google, Tripadvisor and Airbnb.
Ask only happy guests, discourage critical reviews, reward staff for getting reviews or write reviews of your own business or competitors (Tripadvisor rules).
Coerce or pressure guests for a specific rating, or solicit fake reviews (Google, Airbnb).
Delete negative reviews: no property can. Pressuring or paying a guest to remove one is also prohibited.
Published consequences: Google may block new reviews, unpublish existing ones for a set period and show a fake-review warning; Tripadvisor may lower your position and add a red alert.

How much do these scores weigh in AI?

Official information is only partial:

Google: in hotel search, ratings are one of the relevance factors, and AI Mode presents options «complete with guest reviews». How much they weigh inside AI Mode: not confirmed.
Booking.com: the default order depends on clicks and bookings, which Booking.com says depend on many factors, including review scores.
ChatGPT, Gemini, Claude, Copilot or Perplexity: we found no official source on how they use these scores. Not confirmed.
Nobody can guarantee that a good score will make you appear in an AI.
