What Is a Hotel Metasearch Engine?

A hotel metasearch engine is a comparison site that shows, for one hotel and one set of dates, the prices offered by several sellers: the OTAs and the hotel's own website. Google Hotels, trivago, Tripadvisor and Kayak are the best known. The traveler picks an offer and is sent to that seller to book.

Key takeaways

• A metasearch engine compares and redirects; it does not sell the room itself.
• Billing models now differ by platform: Google Hotel Ads charges per click or on a ROAS target, while trivago moved to commission only on September 1, 2025.
• For a hotel, metasearch is the place where the direct rate sits right next to the OTAs' rates.

How does a hotel metasearch engine work?

Each seller, whether an OTA or the hotel itself, sends its rates and availability to the metasearch engine through a price feed. When a traveler searches for a destination and dates, the engine lists the hotels, then shows for each one the prices of the different sellers.

The traveler clicks on the offer of their choice and lands on that seller's site to book. For the hotel, the feed usually goes through its booking engine or channel manager, which must be connected to each platform.

Which metasearch engines matter for hotels?

A handful of platforms carry most of the traffic:

• Google Hotels: the price module shown in Search, Maps and Google Hotels, with paid Google Hotel Ads and free booking links.
• trivago: a dedicated hotel comparison site, strong in Europe.
• Tripadvisor: reviews and price comparison on the same page.
• Kayak and Skyscanner: travel comparison sites that also cover hotels, useful for some source markets.

How do hotels pay for metasearch?

Each platform has its own model, and they have changed in recent years:

• Google Hotel Ads: cost per click, a percentage of the room price per click, or a target return on ad spend. Commission bidding ended on February 20, 2025. Free booking links remain at no cost per click.
• trivago: since September 1, 2025, its Rate Connect program works only on cost per acquisition, a commission paid on completed stays.
• Tripadvisor and Kayak: mainly paid per click through their hotel advertising programs.

In practice, the hotel sets a budget or a commission rate per market and per platform, and measures the direct revenue each one generates.

Why does metasearch matter for direct bookings?

Metasearch is where a traveler sees, at a glance, whether the hotel's own website is cheaper than the OTAs. If the direct rate is equal or better, and visible, many travelers book direct. If the hotel is absent, only the OTAs appear next to its name.

Two conditions matter. The direct rate must be competitive: in Europe, Booking.com can no longer impose rate parity clauses under the Digital Markets Act. And the booking engine must load fast and show the same price as the comparison site.

How does a hotel get started on metasearch?

Three steps are enough to begin:

• Check the connection: ask your booking engine or channel manager which metasearch engines it connects to.
• Start free: activate Google's free booking links through your Google Business Profile and connectivity partner.
• Test a paid budget: one or two platforms, on your main source markets, measured on direct revenue.

How does Influence Society use metasearch?

At Influence Society, we treat metasearch as part of each hotel's direct-booking plan: we check rate parity and the price feed first, open free listings, then test paid campaigns market by market. Each platform is kept only if its direct revenue beats the cost of the same bookings through OTAs.
