1. What is a Metasearch Engine? Definition and History

A metasearch engine is a higher-level search engine that collects results from multiple search engines or booking sites and displays them in one consolidated list. It does not have its own index but instead processes and filters results, removing duplicates and often ranking them by relevance or popularity.

The concept is not new. The first metasearch engine, MetaCrawler, was created in 1995 by two researchers at the University of Washington. Shortly after, the German-developed MetaGer launched and is still active today. These early platforms paved the way for modern hotel metasearch engines like Google Hotel Ads, Tripadvisor, Kayak, Skyscanner, and Trivago.

2. How Hotel Metasearch Works

In the hotel industry, metasearch engines act as price comparison platforms. They display room availability and rates pulled from various OTAs (Online Travel Agencies) and booking websites in one list.

For travelers, this means they can easily compare hotel prices in real time and book the best deal. For hotels, it opens up a valuable online sales channel in addition to their direct website and OTA partnerships.

3. Difference Between OTAs and Metasearch Engines

It’s common for hoteliers to confuse OTAs and metasearch engines. Here’s the distinction:

• OTAs (Online Travel Agencies) – Platforms like Booking.com, Expedia, or Hotel.de sell rooms on behalf of hotels and charge a commission per booking. They manage the full booking process.
• Metasearch engines – Platforms like Trivago, Tripadvisor, and Google Hotel Ads aggregate search results from OTAs and booking sites, showing them side by side. In many cases, metasearch now also offers instant booking, blurring the line between OTAs and metasearch.

4. Key Metasearch Platforms for Hotels

Some of the most relevant travel metasearch engines include:

• Google Hotel Ads – Directly integrated into Google search results.
• Trivago – Focused on global hotel price comparisons.
• Tripadvisor – Combines reviews with metasearch listings.
• Kayak – Part of Booking Holdings, offering price comparisons for flights and hotels.
• Skyscanner – Known for flights but increasingly important for hotel searches.

Each platform has its own pricing model and advertising options.

5. Benefits of Metasearch Marketing

For hoteliers, metasearch represents a chance to:

• Increase online visibility in a competitive market.
• Reach price-sensitive travelers who compare before booking.
• Drive direct bookings by connecting your own website to the metasearch feed.
• Control marketing budgets via pay-per-click or commission-based models.
• Compete with OTAs on the same playing field.

‍

6. Advertising Options on Metasearch Engines

Hotels can appear on metasearch results through two main paths:

1. Via OTAs – By being listed on platforms like Booking.com or Expedia, your hotel will automatically appear in metasearch results.
2. Direct connectivity – By connecting your channel manager or PMS (Property Management System) directly to the metasearch engine, you can display your official website rates.

Pricing Models

• Pay-per-click (PPC) – You pay only when a traveler clicks on your listing.
• Pay-per-impression (CPM) – Charges are based on how many times your ad is displayed.
• Commission per booking – Similar to OTA models but often with lower commission rates.

Choosing the right model depends on your marketing strategy and budget planning.

7. Challenges and Best Practices for Hoteliers

While metasearch is powerful, it comes with challenges:

• Costs – PPC can be expensive if not tracked correctly.
• Competition – OTAs often outbid hotels for top positions.
• Data accuracy – Rates and availability must update in real time to avoid overbookings.

Best practices include:

• Work with a reliable channel manager to keep rates synced.
• Start with small budget tests before scaling campaigns.
• Always compare ROI between OTAs, direct bookings, and metasearch.
• Highlight unique selling points (e.g., free breakfast, flexible cancellation) in your direct booking link.

‍

8. Future Trends in Hotel Metasearch

The metasearch landscape is constantly evolving. Current and future trends include:

• Instant booking features that reduce the need for OTAs.
• Artificial Intelligence (AI) for personalized search results.
• Mobile-first design as more bookings happen on smartphones.
• Voice search integration for travelers using assistants like Alexa or Google Assistant.

Hotels that adapt early to these changes will gain a competitive edge.

Yes. Independent hotels can compete by connecting their direct booking engine to metasearch platforms and carefully managing budgets.

What’s the difference between metasearch and OTAs?

Conclusion

Metasearch engines have become an essential part of hotel distribution. They help travelers compare prices quickly while offering hoteliers a flexible advertising channel.
