About Domaine Château d’Ermenonville

Domaine Château d’Ermenonville is a historic château hotel set within a large wooded estate north of Paris. The property attracts a mix of leisure travellers, weddings, and weekend escape demand.

To unlock more predictable performance and reduce dependence on seasonal fluctuations, the hotel implemented AdsPlus in February 2026 to optimise Google Ads, Meta, and Google Hotel Ads using AI-driven bidding and cross-channel signal optimisation.

The Challenge

Before AdsPlus, performance across paid channels was limited and inefficient:

Low and inconsistent Google Ads returns
Underperforming ROAS (average ~2.7x)
Meta completely inactive as a revenue channel
Google Hotel Ads delivering sporadic results without scale
Overall reliance on low-volume, high-variance demand

The opportunity was clear: demand existed, but campaigns were not structured to capture and scale it efficiently.

The Solution

AdsPlus unified optimisation across all paid channels, shifting from siloed campaign management to a full-funnel, signal-based approach.

Key improvements included:

AI-driven budget allocation based on booking value
Cross-channel learning between Google Ads, Meta, and Hotel Ads
Automated bid optimisation aligned with revenue outcomes (not just clicks)
Rapid activation of previously underperforming channels

Results

Google Ads — strong scaling in efficiency and volume

Bookings: 5 avg/month → 23 avg/month
Improvement:
- 4.9x increase in bookings
- 5.0x increase in revenue
ROAS: ~2.7x → ~11.7x

Meta (Facebook / Instagram) — new revenue channel activated

Meta transitioned from zero contribution to a consistent acquisition channel within two months, adding incremental demand rather than redistributing existing traffic.

Google Hotel Ads — scaled efficiency channel

Growth from 0 bookings (pre-implementation) to 15 bookings (Apr 2026)
Sustained efficiency around ~9–13x ROAS

Key takeaway

Domaine Château d’Ermenonville shifted from fragmented, low-efficiency paid media to a structured, AI-optimised acquisition system.

The impact was clear:

Nearly 5x growth in bookings and revenue from Google Ads
Successful activation of Meta as a performance channel
Strong scaling of Google Hotel Ads efficiency
Consistent multi-channel revenue growth within weeks of activation

AdsPlus enabled the property to move from unpredictable paid performance to a scalable direct booking engine.
