Hotels worldwide are being targeted by roughly 1.1 million ads from Predatory online travel agencies (OTAs) running against searches for their own brand names, potentially diverting guests who were already searching for a specific property away from its direct booking channel, according to new research published today by hospitality technology company Operto.
First-of-its-kind analysis finds approximately 204,000 hotels affected across 205 countries, as operators warn third-party sites are intercepting guests already searching for a specific property.
The analysis found approximately 204,000 hotels across 205 countries and territories were targeted during the study period, with the average affected hotel facing 3.9 competing ads against searches for its own brand.
The findings come from an independent analysis of the Google Ads Transparency Center covering May 22 to June 21, 2026. Operto says it is the first analysis to quantify the scale of Predatory OTA advertising globally.
Predatory OTAs are third-party booking sites that bid on a hotel’s own name in paid search and direct prospective guests to their own booking pages. Unlike traditional distribution partners which can generate new demand for a property, these sites hold no direct contractual relationship with the properties they advertise. They source inventory through bed banks and affiliate networks, then reproduce a hotel’s name, photos, and branding on booking pages that can leave guests believing they are dealing directly with the property.
US hotels carry the heaviest concentration
The United States accounts for 33% of all properties targeted globally, equivalent to approximately 66,900 hotels. North American hotels are targeted by an average of 6.6 predatory ads each, compared with a global average of 3.9. The US also recorded the highest volume of advertising activity in the analysis, with approximately 575,000 ads identified during the 31-day study window.
Nearly half of measured activity traces to one operator
GuestReservations.com accounted for approximately 540,000 ads during the study period, close to half of all predatory hotel advertising identified by the research. ReservationDesk.com followed with around 240,000 ads and BookOnline.com with around 90,000. In total, just nine domains accounted for the activity identified in the analysis.
Guests report booking confusion, cancellation issues and unexpected fees
The impact extends beyond the search results. Operto reviewed 232 published Better Business Bureau complaints filed against GuestReservations.com between July 2023 and May 2026. Among those reviewed, 46% referenced cancellation policies the complainant described as deceptive or false, 38% came from guests who said they believed they had booked directly with the hotel, and 34% referenced hidden or undisclosed fees. A further 5% involved guests arriving at a property that had no record of their reservation.
Hotels can lose the direct booking and inherit the problem
For hotels, the commercial impact can continue after the booking is made. A property can lose a direct booking to an intermediary despite already having won the guest’s consideration, while complaints over fees, cancellations or missing reservations can ultimately reach hotel staff.
Among Operto’s own customer base, affected hotels saw between 5% and 25% of bookings arriving through a Predatory OTA before adopting brand protection, with an average of nine Predatory OTAs bidding on a single hotel’s name.
That can mean paying distribution costs on demand the hotel had already generated itself, while also leaving front desk and reservations teams to resolve issues created elsewhere in the booking journey.
Tim Major, CEO of Operto said:
A guest typing a hotel’s name into Google is one of the strongest signals of direct booking intent a hotel can get. Our research shows that, on average, nine sites can be waiting to intercept that guest before they reach the hotel’s website.
The challenge for hoteliers is visibility. A GM can search the property from the front desk, see nothing unusual and reasonably assume there isn’t a problem, while a guest hundreds of miles away is being shown a completely different set of results. Hotels need to understand who is advertising against their brand, how much direct demand may be leaking through those channels, and what that is costing them.
