Trivago answers one question: which site is selling this hotel room cheapest tonight? It compares rates from hundreds of booking sites across millions of properties, it costs travellers nothing, and its app holds a 4.8 rating from more than 600,000 combined reviews. It also paid one of the largest consumer-law penalties in Australian history for how it once ranked those deals. Both facts belong in an honest review. This guide explains how trivago actually works, where the savings are real, and the three habits that get you the genuinely cheapest rate. We researched it using trivago’s investor filings, its own help pages, app-store data, regulator documents, and aggregated user reviews, in line with our research methodology.
Trivago at a glance
- ✅ What it is: a hotel metasearch engine that compares prices across booking sites; you book on the partner site, not on trivago
- ✅ Founded: 2005 in Düsseldorf; majority-owned by Expedia Group; listed on NASDAQ as TRVG
- ✅ Scale: 2.5 million+ properties in around 190 countries, per trivago’s help centre; the app passed 100 million downloads
- ✅ Cost to you: free, with no booking fees; booking sites pay trivago per click
- ✅ Best for: quickly shortlisting hotels and catching outlier deals across sites you would never check individually
- 👎 Watch out for: the most prominent result is an advertising position, not automatically the cheapest price; always sort by price yourself
- ⭐ Our rating: 3.8 / 5
Trivago vs the main alternatives
Metasearch and booking sites solve different problems. Here is where trivago sits.
| Platform | Type | Who you book with | User fees | Best use |
|---|---|---|---|---|
| Trivago | Metasearch (price comparison) | The booking site you click through to | None | Comparing one hotel’s price across many sites |
| Booking.com | Online travel agency | Booking.com directly | None (rates may include markup) | One-stop booking with strong cancellation options |
| Google Hotels | Metasearch | Partner site or hotel direct | None | Fast price checks straight from search results |
| Hotel direct | Direct booking | The hotel | None | Loyalty perks, room upgrades, flexible changes |
The practical takeaway: trivago is a research layer, not a booking site. It shows you the market in one screen, then hands you off. That makes it a natural first stop before committing anywhere, the same way we use comparison layers in our Klook review for tours and activities.

What is trivago?
Trivago launched in Düsseldorf, Germany in 2005, founded by Rolf Schrömgens, Peter Vinnemeier, and Malte Siewert, according to Wikipedia. Expedia Group bought a majority stake in 2013 and still controls roughly 60% of the company, which listed on NASDAQ in December 2016. The business model is cost-per-click advertising: booking sites pay trivago when you click their rate, and that referral revenue made up €532.9 million of the company’s €548.9 million total revenue in 2025.
2025 was the year the model turned profitable again. Full-year revenue grew 19% and trivago posted €11.2 million in net income, its first full-year profit after a €23.7 million loss in 2024, per its February 2026 results release. “We’re thrilled to share the results of an exceptional year 2025,” said CEO Johannes Thomas in that announcement. The product is evolving too: in November 2024 trivago launched Smart AI Search, a natural-language search built with Google Cloud, so you can type “quiet hotel near the Tube with parking under £150” instead of stacking filters.
How trivago works, and the catch to understand
Search a city and dates, and trivago returns hotels with a prominent headline rate next to a list of competing offers from different booking sites. Click one and you leave trivago to complete the booking on that site. Payment, confirmation, changes, and refunds all happen with the booking site, not with trivago.
Now the catch. The most visible deal position is influenced by how much the booking site pays per click, not purely by price. This is not speculation: Australia’s Federal Court found in 2020 that trivago’s algorithm weighted the cost-per-click fee heavily, and that the highest-priced-bidder’s offer took the top position in 66.8% of listings during the period examined, per the ACCC. The court ordered trivago to pay A$44.7 million in penalties in 2022 and imposed a five-year injunction on labelling non-cheapest offers as top deals. Trivago changed its site after the ruling: strike-through price comparisons and “best price” wording were removed, and ranking disclosures were added.
The lesson survives the lawsuit and applies to every metasearch engine, including this one today: the highlighted deal is an ad slot; the cheapest deal is in the full list. Tap through to the complete price list for a hotel and sort low to high yourself. Used that way, trivago does exactly what it promises.
What trivago is genuinely good at
- Exposing the spread. The same London room can vary by £20 to £50 a night across booking sites. Seeing eight prices side by side is the entire value proposition, and no single booking site will ever show you that.
- Price alerts. Save a hotel in the app and trivago notifies you when the rate drops, which is free leverage for trips booked weeks ahead.
- Smart AI Search. The natural-language search launched in late 2024 handles specific requests (“family room, breakfast included, near the beach”) better than traditional filter stacks.
- A polished app. 4.8 out of 5 from roughly 279,000 App Store ratings and 4.8 from about 370,000 Google Play ratings as of July 2026, with 100 million+ downloads. Whatever travellers think of individual bookings, the comparison tool itself is liked.
What travellers complain about
Trivago’s own Trustpilot pages tell a rougher story than its app stores: the main trivago.com profile sits near 2 out of 5 from roughly 1,200 reviews as of July 2026. Read the complaints closely, though, and most are about the third-party booking sites people clicked through to, not the comparison engine itself: slow refunds from discount partners, bookings cancelled and only discovered at check-in, and prices that changed between the trivago listing and the partner’s checkout. One February 2026 reviewer summed up the frustration bluntly: “The worst service and customer service ever!”
Two practical defences follow. First, when the cheapest rate comes from a booking site you have never heard of, spend thirty seconds checking that site’s own reviews before paying; a £5 saving is not worth a check-in surprise. Second, remember where responsibility lives: your contract is with the booking site, so refund and cancellation requests go to them, and paying by credit card adds chargeback protection if a partner fails you.
Pros and cons
👍 What we like
- Free, fast comparison across hundreds of booking sites and 2.5 million+ properties
- Price alerts and AI search that genuinely shorten research time
- Excellent apps: 4.8 ratings on both stores from 600,000+ combined reviews
- Post-2022 transparency: ranking disclosures replaced the misleading displays regulators punished
- A profitable, Expedia-backed public company, not a fly-by-night deals site
👎 What to watch
- Prominent placements are influenced by advertising fees, so the top deal is not always the bottom price
- Cheapest rates often come from lesser-known booking sites with mixed service records
- Trivago cannot fix booking problems; refunds and changes depend entirely on the partner you booked with
Final verdict: is trivago worth using?
Trivago earns a 3.8 out of 5 as a research tool, which is what it actually is. Used lazily, clicking the first highlighted deal, it is no better than going straight to a booking site. Used properly, it is the fastest free way to see a hotel’s entire price landscape: search, open the full price list, sort by total price including taxes, vet the booking site if it is unfamiliar, and set a price alert if your dates are flexible. Do that and the savings are real, particularly on mid-range city stays where the spread between sites is widest. Book the winning rate with a credit card, keep the confirmation from the partner site, and trivago has done its one job well.

Frequently asked questions
Is trivago legit?
Yes. Trivago is a Düsseldorf-based public company founded in 2005, majority-owned by Expedia Group and listed on NASDAQ, with €548.9 million in 2025 revenue. It is a legitimate comparison engine; your actual booking contract is with the partner site you click through to, so vet unfamiliar booking sites before paying.
Does trivago charge booking fees?
No. Trivago is free for travellers and adds no fees. It earns money from booking sites, which pay per click when you follow one of their rates. Whatever price the partner site shows at checkout is what you pay them directly.
Is the top trivago result the cheapest price?
Not necessarily. Prominent positions are influenced by what booking sites pay per click, a practice Australian courts penalised in 2022 when the top position matched the cheapest offer only a third of the time. Open a hotel’s full price list and sort by total price yourself; the genuine cheapest rate is always in the list.
Trivago vs Booking.com: which should I use?
Use both in sequence. Trivago shows you the price spread across many sites, including Booking.com, in one view. Booking.com is where many travellers end up for its cancellation flexibility and support. Compare on trivago first, then weigh whether a slightly cheaper rate from an unknown site beats a known one’s service.
Who do I contact if something goes wrong with my booking?
The booking site you completed the reservation with, not trivago. Trivago never takes your payment, so it cannot issue refunds or change bookings. Keep the partner site’s confirmation email, contact their support first, and use your credit card’s chargeback protection if a paid booking is not honoured.
