The Challenge
Smile Box Dental, a leading clinic in Bangkok, experienced a sharp decline in new patient bookings after the pandemic disrupted inbound tourism. While their in-clinic service quality was top-notch, they struggled online with:
- An outdated website with poor user experience and mobile performance
- Inefficient Google Ads campaign due to broad matches watsting spend
- Lack of lead tracking and unclear attribution
- Over-reliance on foot traffic from tourism
The Strategy
We implemented a two-pronged solution focused on:
Revamping the website to drive more conversions
Rebuilding their Google Ads (SEM) strategy to capture high-intent leads and maximise budget efficiency
Led to expanding through Google Performance Max

- Created a real-time dashboard to monitor lead sources and ROI

- Added negative keywords to cut waste and boost relevance
2.2 Ad Copy & Landing Page Alignment
