1.1 Million Hotel-Branded Ads Linked to "Predatory OTAs" in One Month

Look-alike booking sites are buying ads on your hotel's name, and they are doing it at scale. A new report from hospitality tech company Operto, first covered by PhocusWire, puts a number on it: 1.1 million ads in a single month.

Operto's State of Predatory OTAs 2026 analysed the Google Ads Transparency Center for the 31 days from May 22 to June 21, 2026. It found those ads targeted searches for 204,000 hotels worldwide. The average affected hotel faced 3.9 competing ads for its own brand. US hotels fared worst, at 6.6 ads each. Nearly half of the ads came from GuestReservations.com. Others included Room77.com, HotelsOne.com, Reservations.com and ReservationCounter.com.

What guests say

Operto reviewed 232 Better Business Bureau complaints against GuestReservations.com, filed between July 2023 and May 2026. Of those, 46% cited cancellation policies the guest felt were deceptive or false. 38% believed they had booked directly with the hotel. 34% pointed to hidden fees. And 5% arrived to find no reservation on record.

For hotels, the cost is twofold. They lose direct bookings, and they take the blame when guests discover the fees or the missing booking. The sites typically show rates above the best available rate, which earns them a larger commission.

One example from the report: Alaska Frontier Inn found that 25% of its bookings were being intercepted by such sites. Its own reservation system showed some of those bookings arriving through Booking.com or Expedia.

Legal pressure, with doubts

This summer, San Francisco City Attorney David Chiu sued GuestReservations.com and BookOnline.com under California's Unfair Competition Law. The suit also alleges that Booking Holdings aided and abetted the scheme by acting as the sites' hotel inventory supplier.

Expedia declined to comment. PhocusWire contacted Booking.com, GuestReservations.com and BookOnline.com, and the article reports no responses.

Operto CEO Tim Major was cautious about the lawsuit. He said similar actions elsewhere have failed because the ads carry enough disclaimer language to avoid liability. The problem dates back to 2015, he said, and AI tools now let operators scale up and refine their tactics. Operto is building AI "investigator" agents that find these sites and report them to Google for removal, though Major described the work as "Whac-A-Mole" because blocked operators can set up new shell companies quickly. He also argued that affiliate networks and major OTAs disown these sites but rarely enforce their own terms against them.

What operators can do

Search your own hotel name regularly and note which ads appear. Check where mystery bookings come from in your reservation system, especially ones tagged to big OTAs that you did not expect. If a guest arrives confused about fees, ask where they booked before assuming it was you. And report look-alike ads to Google when you find them.
