Hotel customer acquisition costs have climbed sharply this year as new digital marketing regulations and rising media prices reshape how hospitality brands reach potential guests. Cost per acquisition is up 38%, marking the steepest year-over-year increase in several years, according to new industry data.
The findings indicate that privacy laws, expanded consent requirements and fee-transparency rules are disrupting long-established digital advertising systems. The shift toward a “clickless” environment is weakening tracking capabilities, reducing optimization signals for automated bidding tools and lowering return on ad spend across major markets.
Privacy rules and reduced tracking reshape performance
Cendyn attributes a significant portion of rising costs to the impact of the EU’s Digital Marketing Act, which requires companies to secure explicit user consent before collecting data. The report analyzes Google’s response to these rules, including the introduction of Consent Mode V2, which allows websites to continue using Google advertising and analytics tools while maintaining regulatory compliance.
However, Cendyn found that performance dropped when users declined consent. Without consent, conversions go untracked, limiting the data needed for Google’s automated bidding systems. This reduces the accuracy of optimization, obscures true conversion performance and can lead to misguided strategy shifts for hotels.
The company also reports a decline in conversion rates across most digital channels. According to aggregated data from the Cendyn Digital Marketing Platform, this trend reflects broader limitations caused by reduced cookie-based tracking and diminished access to user behavior data.
New transparency laws affect pricing accuracy and visibility
Alongside privacy regulations, the report identifies new fee-transparency rules as another factor affecting hotel marketing costs. California Senate Bill 644 and Assembly Bill 537 require hotels to clearly disclose taxes and fees, creating additional compliance requirements for rate displays across digital channels.
Cendyn notes that failures in compliance have caused price parity issues across channels, affecting performance on metasearch platforms where rate-sensitive users compare listings. Inaccurate or non-compliant pricing reduces visibility and click-through rates. The report shows CTR in the United States falling from 3.18% to 2.88% as users avoid listings displaying higher rates.
The company warns that technical accuracy, transparency requirements and privacy-first advertising practices have become essential to maintaining visibility and achieving return on investment. “Hoteliers need to take the findings from this report as a warning: non-competitive listings face reduced visibility, or exclusion from search results,” said Christina Leme, Senior Director Global Media at Cendyn.
Leme said hotels have several options to respond to these shifts. “Implementing robust price parity monitoring, optimizing consent management for better tracking, ensuring accurate fee and tax disclosure, investing in first-party data collection and activation – these are all great strategies for securing future bookings,” she said. “In a landscape defined by constant change and increasing regulatory complexity, hotels that stay ahead of these shifts can and will thrive.”
Cendyn notes that hoteliers must continuously adapt to changing regulations, evolving consumer behavior and fluctuating market dynamics. The company’s findings emphasize that hotels using outdated tracking strategies or inconsistent pricing structures risk losing visibility at a time when competition for demand is intensifying.
The Hotel Digital Marketing Performance Index 2025 is designed to give hospitality marketers practical guidance as the industry navigates a more complex digital environment. The report outlines strategies for optimizing spend, improving accuracy and preserving channel performance as privacy rules and compliance obligations grow more stringent.
Available now, the report provides detailed analysis intended to support hoteliers in making data-driven decisions as acquisition costs rise and digital advertising enters a new regulatory era. Cendyn expects that continued adaptation will be essential for hotels seeking to maintain competitiveness and capture demand in a crowded and rapidly evolving marketplace.
