La Chambre du Marais reached 51x ROAS with Google PMax for travel goals

THE CHALLENGE

As part of its partnership with Cendyn, La Chambre du Marais launched Google Performance Max for travel goals (PMTG) campaigns through the Cendyn Digital Marketing Platform (DMP), with the strategic objective of generating high-quality conversions while maximizing return on ad spend (ROAS).

By leveraging the advanced capabilities of the Cendyn DMP and the AI-powered targeting and automation of Google PMTG, the property aimed to reach high-intent travelers at the right time and across the right channels. The goal was to boost online visibility and drive stronger performance for direct bookings.

THE SOLUTION

To maximize the effectiveness of its Google PMTG campaigns, La Chambre du Marais relied on the Cendyn DMP to implement granular language segmentation, allowing messaging to be tailored precisely for each audience.

Striking visual content aligned with the hotel’s premium brand image was created to capture attention and increase engagement. Thanks to ongoing optimization, budget and bidding strategies were adjusted in real-time to capitalize on performance peaks.

The use of Performance Max technology enabled automated ad delivery and conversion optimization while maintaining tight control over cost-per-click, ultimately delivering an exceptional return on investment. The PMax for travel goals campaigns for La Chambre du Marais achieved outstanding results, showcasing the power of these campaigns when paired with a well-crafted strategy and compelling content.

Cendyn truly understood our strategy and objectives and translated them effectively through the Digital Marketing Platform. Their support enabled us to roll out Google Performance Max for travel goals campaigns in a relevant and structured way, with both agility and precision. The quality of execution, combined with ongoing optimization, contributed to strong results. Gabrielle Thomas, Digital Marketing Project Manager, Experimental Group

• In English, results were even more impressive, with 255 conversions, an average CPC of €2.39, and a ROAS of 55.68.
• In Canada, a pilot campaign launched in late April 2025 already shows promise, with an average CPC of €0.40, a ROAS of 4.74, and 3 conversions.

These results highlight the strength and precision of the Cendyn platform in driving high-performance digital campaigns across diverse and targeted markets.
