Hotel star ratings across OTAs: who assigns them, and why yours disagree

The short answer

What most operators get wrong

• Assuming a star rating is a fact. On several channels it is a claim the platform repeats — and Booking.com says it does not impose its own standards or review the rating.
• Treating a difference as a defect. Because the assigners differ, a hotel can show four stars on one channel and a four-star class on another that was inferred, not awarded. Only one of those can be corrected with a certificate.
• Reading the review score as stars. Booking.com's 1–10 score is guest satisfaction, weighted towards recent reviews. It is not a half-star version of the yellow stars beside it.
• Forgetting that classifications expire. A certificate with a lapsed date still shows on your listings until somebody notices, and renewal is a scheduled job, not a support ticket.
• Trying to edit a value nobody gave you. Google's class rating has no certificate step — the documented route is feedback to Google, and the attributes it reads include your price.

Three different numbers get called a rating

Before comparing channels, separate the three things a traveller sees. They have different owners, different inputs and different correction routes, and conflating them is what sends a fixable problem to the wrong place.

Booking.com describes its own display directly: 1–5 yellow stars beside the property name, assigned by the property or a third party, and a separate 1–10 review score from guests, weighted so a more recent review has more impact on the total.

Where each channel's rating comes from

Read each row as one channel and ask a single question: could a certificate change this number? Where the answer is no, the value is the platform's, and your lever is a support conversation rather than an edit.

The four origins the diagram distinguishes are: official rating, where one exists; declared by the property; inferred by the platform; not documented.

Platform by platform

One entry per channel: who sets the number, what the platform says it does to check it, and the documented route to a correction.

Why one hotel shows different stars on different channels

Seven mechanisms, in rough order of how often they explain a difference. Most of them are not errors, which is why the first job is diagnosis rather than a round of support tickets.

1. 1

   Different parties assign it

   Booking.com repeats what the property or a third party declared. Expedia repeats an official rating where one exists and assigns its own where it does not. Google infers a class. Three mechanisms cannot be expected to agree.

2. 2

   Different scales

   Expedia's content model accepts half-stars; a classification scheme that awards whole star levels cannot produce a 3.5. A half-star on a listing is therefore a platform value, not a classification.

3. 3

   Different inputs

   Google names price among the attributes it evaluates, so a sustained rate change or a repositioning can move the class Google shows while every field a hotel controls stays exactly as it was.

4. 4

   Different clocks

   Classifications expire. In France renewal is requested every five years, and Hotelstars Union classifications are valid for a limited period. A listing can keep displaying a rating the certificate no longer supports.

5. 5

   Different evidence thresholds

   Agoda asks for a certificate or a signed checklist before it changes a rating. Booking.com says it does not review star ratings at all unless it becomes aware one is inaccurate. The same property can pass one bar and never be asked to clear the other.

6. 6

   A declaration nobody revisited

   Star ratings are usually entered once, during onboarding, often by whoever set the listing up. Renovations, downgrades, a lapsed classification and staff turnover all happen after that form was submitted.

7. 7

   The review score gets mistaken for stars

   Booking.com's 1–10 review score sits next to the 1–5 stars and measures something else entirely: guest satisfaction, weighted so recent reviews count for more. An 8.9 is not four and a half stars.

Where an official classification exists

Whether a certificate can settle the question depends on your market. This is not a directory of every national scheme — it records the ones the platforms and classification bodies themselves document, and links to the awarding body rather than paraphrasing its criteria.

Disclosing where your stars came from

The question "who awarded this rating?" has moved from housekeeping to a disclosure question, at least in one market with a documented history. Both entries below are dated, and the second is reported rather than read first-hand — which is exactly how it is labelled.

1. 6 December 2018

   The Dutch Advertising Code Commission decided dossier 2018/00684 against Booking.com, holding that advertising hotel stars that had not been awarded by an independent classification body, without any explanation, misled consumers and was therefore unfair under Article 7 of the Dutch Advertising Code.

   Evidence: Primary — the published decision. Stichting Reclame Code

2. 2 April 2026

   The appeals board of the Dutch advertising self-regulator ruled again on star ratings, and Booking.com is reported to have to disclose the source of the star ratings it shows and whether they are verified, so that a traveller can tell an official classification from an unverified or self-assigned claim.

   Evidence: Reported by trade press on 22 April 2026. The decision text itself was not retrievable on the review date, and Dutch advertising self-regulation is not a court judgment — treat the scope as the Dutch market and confirm the current position before relying on it. Travel Weekly

The practical takeaway does not depend on where you operate: be able to name the body that awarded your rating and the date it expires. If nobody at the property can, the number is a claim, and the cheapest time to find that out is before a guest or a regulator does.

Correcting a rating that is wrong

Six steps that keep the request evidenced and the outcome verifiable.

1. 1

   Write down what each channel shows today

   Open every public listing as a traveller and record the number displayed, not the number in the extranet form. Include Google, which shows a class rating rather than a star rating.

2. 2

   Decide which rating is the true one

   If an authority classified the property, the certificate is the answer and every other value is a copy of it. If no authority did, there is no true rating — only what each platform assigned and what the property once declared.

3. 3

   Assemble the evidence before you open a ticket

   A scan of the certificate, its reference number, the awarding body, the award date and the expiry date. Agoda accepts either an official certificate or its own signed checklist, and asking for a change without either is what makes a request stall.

4. 4

   Use the route the platform documents

   Agoda: a request through Need Help with the document attached. Google: contact Google with feedback on the class rating. Expedia: the authority's decision where the market has one, Partner Central support where the value is Expedia-assigned. Booking.com and Trip.com publish no retrievable route, so ask partner support and keep the reply.

5. 5

   Fix the cause, not only the display

   If the classification has lapsed, no ticket will hold. Renew it — in France that means requesting renewal every five years and arranging inspection by a COFRAC-accredited body — and then correct the listings.

6. 6

   Re-check the live pages, then diarise the next check

   Confirm each public page separately; Expedia and Hotels.com come from one listing but are two pages a guest can read. Then set a recurring check, because a platform-assigned or inferred value can move without anyone editing anything.

Working the rating into a wider review? Route the edit with the hotel OTA extranet directory, compare the other field a hotel only half controls with hotel child policies across OTAs, run the field sweep with the OTA content audit checklist, and confirm the change actually rendered using how to verify hotel listing updates.

What this page is not

• Not a ranking guide. Nothing here claims that a particular rating changes position, visibility or conversion on any platform.
• Not legal advice. The Dutch decisions below are recorded because they are published and dated, not as guidance on your own market or contract.
• Not a national-scheme handbook. Where a country classifies hotels itself, the awarding body publishes the criteria and this page points at it instead of paraphrasing it.
• Not a list of every platform. Tripadvisor also displays a hotel class beside its traveller rating, but its owner-facing explanation of how that class is set refused an automated request on the review date, so it is left out rather than guessed at.
• Not a review-score guide. Guest review scores are a different measurement with a different owner; they appear here only because they are so often mistaken for stars.

Scanner scope: A MisMatchMaker scan does not compare star ratings. It reads factual listing content — breakfast, parking, pets, arrival times, cancellation terms, fees — and star ratings are assigned by parties outside the hotel, so a difference between two channels is frequently correct rather than a mismatch to fix. Treat the register on this page as the manual check that sits beside an automated content scan.

Frequently asked questions

Who assigns a hotel's star rating on Booking.com?

Not Booking.com. It states that it does not assign star ratings and that, depending on local regulations, they are assigned either by the properties themselves or by independent third parties such as organisations that rate hotels. It also states that it does not impose its own standards for star ratings and does not review them, but will ask a property to prove or adjust a rating once it becomes aware that the rating is inaccurate.

Why does my hotel show a different star rating on Expedia than on Booking.com?

Because different parties set them. Expedia Group states that a star rating is a value assigned either by Expedia Group or by a local star rating organisation, and that it publishes the official rating in regions where a local authority designates one — it names France, Italy, Turkey, the United Arab Emirates and Israel — while assigning its own value elsewhere. Booking.com repeats what the property or a third party declared. Neither number is a copy of the other, so they can differ without either listing being broken.

Is Google's hotel class the same thing as a star rating?

No. Google calls it a class rating, shows it on a 1 to 5 scale, and gathers the data from third-party partners, its own research, hotelier feedback, and machine-learning inference over hotel attributes such as price, location, room size and amenities. Because price is one of the inputs Google names, a class rating can move without anyone at the hotel changing a field. Hotels with no class rating shown have not yet been evaluated by Google.

How do I change the star rating on my Agoda listing?

Agoda documents this one. A new partner sets a star rating at registration, which Agoda verifies as part of registration. An existing partner has to raise a request through the Need Help button in the partner portal and attach either an official star rating certificate from a hotel rating organisation or government, or a signed Agoda Star Rating Checklist. If no official certification is available, Agoda says it will review the property against the checklist provided, and it states that it does not guarantee the request will be granted or the result of the verification.

Can a hotel give itself stars?

In some markets a self-declared rating is what a listing displays, because the platform repeats what it was told. That is a disclosure risk rather than a free choice: in dossier 2018/00684 the Dutch Advertising Code Commission held that advertising hotel stars not awarded by an independent classification body, with no explanation, misled consumers and was unfair under Article 7 of the Dutch Advertising Code. If nobody at your property can name the body that awarded the rating, treat the number as a claim you would have to defend.

What does a half-star on a listing mean?

It means a platform assigned it. Expedia Group's content model accepts half-star values such as 1.5, 2.5, 3.5 and 4.5, while the Hotelstars Union scheme awards whole star levels with an optional superior tier. A 3.5 therefore cannot be a Hotelstars classification, so it is the platform's own value rather than an official one.

Does a star rating expire?

An official classification does. Hotelstars Union states that each classification is valid for a limited period so that hotels are reviewed regularly, and in France renewal has to be requested every five years, with inspection by a body accredited by COFRAC. A listing can keep displaying a rating the certificate no longer supports, which is why the expiry date belongs in your own record rather than only on the certificate.

Does MisMatchMaker check star ratings?

No. A scan compares factual listing content — breakfast, parking, pets, arrival times, cancellation terms, taxes and fees — and star ratings are assigned by parties outside the hotel, so a difference between two channels is often correct rather than a defect. Star ratings are a manual check: record what each channel displays, keep the classification certificate and its expiry date on file, and use a content scan for the fields you do control.
