CASE STUDY: How I doubled ROAS without increasing spend in Google Ads

When I first took over the account, it was immediately clear that while there was significant investment in paid media, there was little clarity around performance. Dozens of campaigns were actively driving traffic, but there were no defined goals, no conversion tracking in place, and no Google Tag Manager implementation. The property was spending tens of thousands of dollars each month without a clear understanding of return on ad spend (ROAS) or how those dollars translated into actual bookings.

The first priority was to establish alignment. In any marketing effort — especially within a fixed budget — clarity of objectives is essential. I worked closely with the client to define their primary goal: increasing direct room bookings. With that focus established, and a monthly budget of approximately $30,000, I was able to develop a strategy centered on both capturing demand and improving efficiency.

We began by restructuring the Google Ads program. I implemented a dual approach across paid search, balancing brand and non-brand campaigns. Brand campaigns ensured the property maintained visibility against OTAs and protected high-intent traffic that might otherwise be diverted. For non-brand campaigns, I conducted extensive keyword research to identify high-volume, high-intent search terms aligned with the property’s positioning. This included queries such as “family-friendly resort,” “beachfront resort,” and experience-driven searches that reflect how travelers actually research destinations.

In addition to paid search, I introduced a more holistic channel strategy. This included leveraging OTA platforms such as Booking.com, Expedia, and TripAdvisor to maintain visibility across key booking channels, as well as implementing Meta campaigns focused exclusively on retargeting website visitors. This allowed us to re-engage high-intent users who had already expressed interest but had not yet converted.

Equally important was building a reliable measurement framework. Without accurate tracking, optimization is not possible. I implemented Google Tag Manager and connected the property’s booking engine to both Google Ads and Meta via conversion tracking and the Facebook pixel. This allowed us to shift campaign optimization away from surface-level metrics like traffic and toward what truly matters: completed bookings.

From there, I restructured campaigns to align with performance insights. Audiences were segmented — for example, kama‘aina versus mainland travelers — to ensure messaging and targeting were relevant. Campaigns were then optimized for conversions rather than clicks, allowing us to prioritize efficiency and revenue generation.

The second phase focused on continuous optimization. I implemented a structured A/B testing framework across creative, ad copy, and keyword groupings, regularly analyzing performance data including click-through rates, audience demographics, and geographic trends. Budget was actively reallocated toward the highest-performing campaigns and segments, ensuring that spend was always aligned with return.

As performance improved, the results became clear. We were able to increase ROAS from approximately 15 to 30 month-over-month, significantly improving the efficiency of the account. Once that level of performance was consistently achieved, we scaled spend back to the full budget with confidence, knowing that each dollar invested was now working more effectively.

This approach not only drove stronger returns, but also provided the client with clear visibility into performance and a scalable framework for continued growth. By aligning strategy with business goals, implementing proper tracking, and focusing on efficiency at every stage, we transformed the account from a high-spend, low-visibility effort into a measurable and revenue-driven marketing channel.
