trivago N.V. (TRVG)

trivago N.V. (NASDAQ: TRVG) is a travel-technology company headquartered in Düsseldorf, Germany that operates a website and mobile app helping travellers find and book hotel accommodation. The company does not own hotels, does not manage inventory, and does not collect payment directly from travellers. Instead, trivago aggregates prices and availability data from hundreds of sources — hotels, online travel agencies, booking platforms, travel agents — and displays them side by side so a user can compare. When a user clicks on a hotel offer they like, trivago redirects them to the booking partner’s website to complete the reservation. The booking partner pays trivago a referral fee — typically based on a cost-per-click model or a percentage of the booking value. Shares trade on NASDAQ under the ticker TRVG.

What does trivago actually do, and what does it not do?

trivago does not sell hotel rooms. It aggregates information about available rooms and sends interested buyers to the sites where they can actually book. The company is a matchmaker: it brings together travellers seeking accommodation and the platforms or hotels that have inventory to sell. When the matchmaking works and a user completes a booking on the partner’s site, the partner pays trivago a referral fee. This is fundamentally different from a hotel chain, a property manager, or an online travel agency that owns or controls inventory and collects payment directly. trivago owns only the software platform, the user interface, and the relationships with booking partners.

This distinction is crucial because it shapes trivago’s economics entirely. The company has no capital cost to stock rooms, no labour cost to clean them or service guests, and no revenue volatility from occupancy rates or seasonal demand. Instead, trivago’s economics depend on two things: the traffic to its site and the cost of acquiring that traffic relative to the referral fees it generates from partners.

How does trivago acquire users and make money?

trivago spends heavily on advertising to drive traffic to its website and mobile app. The company buys search ads, social media ads, and traditional advertising to build brand awareness and drive visits. The cost of this traffic varies widely depending on the channel, the season, and competitive intensity. A search ad for “cheap hotels in New York” may cost differently in July (high-season travel) than in January (low season), and differently depending on whether competitors are also bidding on the same keywords.

Once a user arrives at trivago, they enter a search query — destination, dates, number of rooms — and trivago returns a list of hotels with prices from multiple sources. A hotel might appear with a price of $150 from the hotel’s direct website, $148 from Booking.com, and $155 from Expedia. The user sees all three, can read reviews, compare amenities, and click on whichever option appeals to them. When they click on a partner’s offer, they leave trivago’s site and land on that partner’s booking page. If they complete the booking, the partner pays trivago a referral fee.

The fee structure is typically cost-per-click — trivago gets paid a fixed amount (say, 1 dollar or 2 dollars) every time a user clicks on a partner’s offer, regardless of whether a booking actually happens. Alternatively, the partner may agree to cost-per-acquisition — trivago only gets paid if the click results in a completed booking. Cost-per-click fees are more predictable for trivago but may overpay for clicks that don’t convert. Cost-per-acquisition is more efficient but requires trivago to have confidence that its traffic will convert well.

In 2025, referral fees accounted for approximately 98 percent of trivago’s revenue, with the remainder coming from direct hotel bookings and premium hotel-listing packages. This concentration in referral fees means trivago’s business is entirely dependent on the continued willingness of partners to pay for traffic. If a partner feels that the cost per acquisition is too high relative to their profit margins, they may reduce their ad spend on trivago or shift their marketing budget elsewhere.

The metasearch moat and competition

trivago’s advantage comes from aggregation. Travellers want one place to see options and compare prices — it is less friction than visiting five different websites individually. This has real value. But the barrier to competition is not high. Competing metasearch platforms exist — Google Hotel Search, Kayak (owned by Booking.com), Hopper, Momondo — and each has carved out a share of the market. Google Hotel Search, in particular, is formidable because it appears directly in Google search results and requires no extra click or visit to Google’s own domain.

trivago’s brand recognition is strong in some markets, especially in Europe and North America, where the company has spent years on advertising and has become a household name among frequent travellers. This brand recognition creates sticky usage — people return to trivago because they know it. However, the switching cost for a user is very low. If another site offers a similar comparison experience, the user will try it. So trivago must constantly maintain product quality and user experience to retain traffic.

What trivago depends on downstream

trivago’s entire business depends on booking partners continuing to buy referral traffic from it. Booking.com, Expedia, Hotels.com, and individual hotels must decide that the referral fee they pay is worth the booking they receive. If the cost per acquisition rises while hotel profit margins compress, partners may reduce spending or exit the channel. During recessions, when travel demand falls, partners have less inventory to sell and may become more selective about where they advertise. During booms, they compete for traffic and spending rises.

The largest risk to trivago is if a major partner like Booking.com or Expedia — both of which own and operate their own vast inventories — decide that they no longer need trivago’s traffic because they can generate enough bookings through their own brand and direct channels. Expedia Group, which owns trivago, faces this inherent tension. Expedia is itself a major booking platform that competes with the partners who pay trivago for referrals. This creates potential conflicts of interest and strategic uncertainty.

Revenue diversification and product expansion

To reduce dependence on cost-per-click advertising, trivago developed Hotel Manager and Trivago Business Studio, products that allow hoteliers to manage their listings, improve their visibility, and run promotions directly on the trivago platform. These products generate subscription fees and are positioned as a way for independent hotels to gain exposure without paying per-click fees. However, these products have contributed only a small slice of revenue — roughly 2 to 3 percent.

The company has also experimented with direct bookings — allowing users to complete a reservation directly on trivago’s site rather than being redirected to a partner. Direct bookings would allow trivago to capture a larger share of the transaction value. However, direct booking is operationally complex (trivago would need to manage payments, cancellations, and customer service) and requires negotiation with hotels to access their inventory at wholesale prices. This push has not yet materially changed the revenue mix.

How to research trivago as an investment

Start with the company’s latest annual report and quarterly earnings filings (SEC CIK 0001683825), which detail revenue by geography and source, customer acquisition costs, and the performance of the core referral business. These documents will show whether referral fees are growing or shrinking, and whether the company is successfully monetising its user base at higher rates. Watch the number of active users and the cost per click; a rising user base paired with stable or declining cost-per-click indicates improving unit economics. Conversely, rising cost-per-click despite stable users suggests competitive intensity is eroding margins.

Also monitor the health of the hotel and travel industries. Trivago’s business is pro-cyclical — when travel is booming and hotels have high occupancy, they spend more on marketing and on paying trivago for referrals. During travel downturns, this advertising spending falls quickly. The earnings calls will include management commentary on booking partner behaviour, pricing pressure, and any changes in the affiliate landscape. Finally, pay attention to trivago’s parent, Expedia Group, and any changes in Expedia’s strategy regarding how it supports or competes with trivago’s business.
