1.1 million ads are bidding on hotel names, and nine domains placed all of them

Operto has counted how much paid search advertising is aimed at hotel brand names, and the numbers are larger than most operators would guess. It found roughly 1.1 million ads targeting hotel-branded searches, affecting around 204,000 hotels.

The study ran over 31 days, using Google Ads Transparency Center data from 22 May to 21 June 2026. Short Term Rentalz reported the findings on 12 October.

Nine domains

The concentration is the most striking part. Nine domains accounted for all of the advertising Operto identified. GuestReservations.com alone was responsible for close to half of it.

Operto calls these advertisers predatory OTAs, and its definition is specific: they bid on individual property names without holding a direct contract with the property, and they source the inventory they sell through bed banks and affiliate networks.

The guest-side evidence is the part worth reading twice. Operto reviewed 232 Better Business Bureau complaints against GuestReservations.com. Thirty-eight percent came from guests who believed they had booked directly with the hotel.

Tim Major, Operto's CEO, said hotels need to understand who is advertising against their brand, and how much direct demand may be leaking through these channels.

The conflict to note

Operto sells hospitality technology, including products in the direct booking and guest experience space. A study concluding that direct bookings are being intercepted is a study that supports what Operto sells. That does not make the Google Ads Transparency data wrong, and the method is checkable by anyone, but the framing is not neutral and the full report sits behind a request to Operto.

What it means for operators

If a guest books your hotel through one of these intermediaries believing it was you, several things follow and all of them land on your front desk.

The rate the guest paid is not your rate, and the difference is not yours either. The reservation arrives through a bed bank, so loyalty numbers, stated preferences and often a usable email address do not arrive with it. Your PMS receives a booking with a third-party reference attached to a guest who thinks they have a direct relationship with you. Change and cancellation requests come to you first, and you usually cannot action them.

Then the complaint, and often the review, is about your hotel.

The first practical step is cheap and takes ten minutes. Search your own property name in an incognito window and look at what sits above the organic result. Then check the Google Ads Transparency Center for your own brand terms. It is free, and it is the same source Operto used. If somebody is bidding on your name, you now know who, and roughly how hard.

What to do next is harder, because bidding on your own brand name costs money you were not spending and the intermediaries will keep bidding anyway. Most independents end up defending the top spot on their highest-intent terms only. The thing worth measuring before you spend anything is how much of your direct traffic is actually exposed, which the transparency data will tell you for nothing.
