The best hotel search engine depends on who is paying and how many rooms you need. A big online travel agency or a price comparison site covers most personal trips, a travel management platform covers trips booked for a company, and group booking tools take over at nine or more rooms.
This guide covers 32 hotel search engines in five types, with a quick pick for each kind of trip first and a short entry on every site after.
What is a hotel search engine?
A hotel search engine is a website or app that finds hotel rooms and rates for a destination and set of dates. Some sell the room and take your payment. Others compare rates across sellers and send you to one of them to book.
What are the main types of hotel search engines?
Hotel search engines fall into five types. The type decides whose prices you see and who you pay.
Online travel agencies
An online travel agency (OTA) lists its own hotel rooms and rates and takes your payment, or has you pay the hotel at check-in. Booking.com, Expedia, and Hotels.com are the largest. Two companies, Booking Holdings and Expedia Group, own almost all of them.
Metasearch engines
A metasearch engine, also called a hotel comparison site, shows one hotel's rate on several booking sites side by side and links you out to book. Google Hotels, Kayak, and Trivago are metasearch engines. They do not sell rooms.
Business travel platforms
A business travel platform sits behind a company login and adds what consumer sites leave out: pre-negotiated business rates, travel policies, and billing to the company instead of a personal card. Engine, Navan, and SAP Concur are examples.
Hotels agree to show the same public price on every OTA, an arrangement called rate parity. Business travel platforms sit behind a login, so a hotel can offer a lower business rate there without breaking that agreement.
Group booking tools
Most consumer sites stop at eight or nine rooms per booking. Group booking tools handle room blocks, group rates, and the contract for nine rooms or more at one property.
Niche hotel search engines
A niche engine does one thing well that the general sites only approximate with a filter: rooms for tonight, pet policies, day rooms, truck parking, or hostels.
How is a business hotel booking different?
Business travel platforms filter and price for a different trip than consumer sites. Engine booking data for US business hotel stays over the past 12 months shows the pattern:
- 58% of bookings are made the same day as check-in, and 74% within two days.
- 56% are one-night stays.
- 72% of check-ins are Monday through Thursday. Monday alone is 25%.
- 94% are at branded chains. Choice, Hilton, IHG, Wyndham, and Marriott brands account for 80% of bookings.
- 81% are 2.5 or 3 star properties.
Online travel agencies
OTAs sell you the room. Two companies own most of them, so the same hotel rooms show up under several brand names.
Booking.com
The largest OTA by property count, with hotels, apartments, and hostels in one search and free cancellation on many rates. Owned by Booking Holdings, which also owns Priceline, Agoda, and Kayak.
Expedia
Flights, hotels, and rental cars in one cart, with package pricing when you bundle. Expedia Group also owns Hotels.com, Travelocity, Orbitz, Hotwire, Vrbo, and Trivago, so those sites share most of the same rooms.
Hotels.com
Expedia Group's hotel-only storefront. Same rooms as Expedia, with a hotel-first interface and the group's loyalty program.
Travelocity
Another Expedia Group storefront aimed at leisure travelers, with its own promotions on the same hotel rooms.
Orbitz
An Expedia Group storefront with a long record of LGBTQ+ travel content and its own promotions.

Trip.com
A China-based OTA with strong hotel coverage across Asia and train tickets for Europe and Asia in the same app.
Metasearch engines and hotel comparison sites
Metasearch engines do not sell rooms. They show one hotel's rate on several booking sites, then send you to the site you pick.
Google Hotels
Rates from booking sites and the hotel's own site, shown next to the map result. Hotels can list for free, so it shows more sellers per hotel than any other comparison site.
TripAdvisor
The largest review base of any travel site, with a price comparison strip on each hotel page. You book on the site you choose.
Kayak
Flights, hotels, and rental cars, with price alerts and detailed filters. Owned by Booking Holdings.
Trivago
Hotel-only price comparison across booking sites. Majority owned by Expedia Group.
HotelsCombined
Hotel-only comparison on Kayak's engine, for the same results without flights and cars.
Momondo

Business travel platforms
Business travel platforms and travel management companies sit behind a company login. You get business rates, billing to the company, and travel data in one place.
Engine
Engine is a travel management platform for every kind of business. Book hotels, flights, and rental cars at pre-negotiated business rates, set travel policies, put the whole company on one invoice, and earn Engine Rewards on top of hotel loyalty points.

Navan
A travel and expense platform with its own corporate card, aimed at mid-size and large companies. Engine and Navan announced a technology partnership in September 2026.
SAP Concur
Expense management with travel booking, common at large companies that already run SAP. Expect a long implementation and per-user pricing.

Group booking tools
Group tools handle the room block, the contract, and the group rate for nine rooms or more at one property.
Engine Groups

Frequently Asked Questions About Hotel Search Engines
What is the difference between an OTA and a metasearch engine?
An online travel agency (OTA) such as Expedia holds the hotel rooms and takes your payment. A metasearch engine such as Kayak shows the same room's price on several OTAs and hotel sites, then links you out to book.
Are hotel search engines cheaper than booking direct?
Public rates are usually the same everywhere because hotels agree to rate parity across OTAs. Booking direct adds loyalty points and simpler changes. Business travel platforms such as Engine show pre-negotiated business rates behind a company login, which hotels can price differently from public rates.
What is the best hotel search engine for business travel?
For travel booked on a company's behalf, a travel management platform such as Engine gives you business rates, one invoice, travel policies, and reporting that consumer sites do not offer. For an occasional solo work trip on a personal card, any major OTA works.
Which hotel search engine has the most hotels?
Booking.com and Expedia list the most properties, and their sister brands cover most of the OTA market between them. Google Hotels shows the widest set of sellers for any one hotel because hotels list there for free.
Can I book a group on a regular hotel search engine?
Most consumer sites cap a single booking at eight or nine rooms. For nine or more rooms, use a group booking tool such as Engine Groups or HotelPlanner, which arrange a room block and a group rate at one property.
Is Google Hotels a booking site?
No. Google Hotels compares rates and links to the OTA or hotel site where you complete the booking. Google does not take the payment.
