One Day Agency Expands International Work With Keto-Mojo

One Day Agency is expanding its work with Keto-Mojo, adding responsibility for the UK alongside further activity across 21 countries.

The expansion follows positive early results in Germany, France, Poland, the Netherlands, Ireland and Austria, where the agency has managed performance marketing since May 2026.

The wider remit brings creative development and paid media together, with One Day working closely with Keto-Mojo’s internal marketing team to shape activity for different audiences.

Building on Six European Markets

Keto-Mojo specialises in blood ketone and glucose monitoring devices that help consumers understand and manage their metabolic health. Its international customer base includes people following ketogenic lifestyles and those using biomarker data to inform decisions about health and nutrition.

Across the original six markets, One Day’s campaigns combine Google Search, Shopping and Performance Max with Facebook and Instagram advertising.

Creative concepts and video content are tailored to individual countries, maintaining a consistent brand identity while reflecting local audiences.

Daniel Scarffe, Senior Paid Search Manager at One Day Agency, said:

“Our focus has been on identifying where the biggest growth opportunities are across different markets and building a strategy around them. We’ve combined Google Ads, paid social and creative to reach new audiences and drive sales, adapting our approach based on what’s working in each country.”

Planning for Further International Growth

The next phase will draw on those market learnings to guide investment and campaign development across the additional territories.

Search-demand research and customer journey analysis will inform planning, alongside opportunities to diversify channels. Market-specific activity will also address key buying periods, including Black Friday and January.

Alexandra Gonçalves, One Day’s Senior Paid Social Media Manager, added:

“As we expand into new markets, our priority is to build on these learnings and develop a scalable growth strategy that remains responsive to the unique dynamics and opportunities of each market.”

Extending the Work Beyond Paid Media

One Day’s broader role combines creative production with strategic consultancy and ecommerce analysis to support Keto-Mojo’s international plans.

Working alongside the brand’s internal team will allow the agency to connect campaign development with local market priorities, using experience from the existing territories to inform the rollout.

Christi Terjesen, Head of Marketing at Keto-Mojo, said:

“As Keto-Mojo continues to expand internationally, it’s important that we balance global brand consistency with a localised approach to each market. One Day has demonstrated a strong understanding of our business and the nuances of performance marketing across Europe. We consider their team an extension of our own, and we’re excited to build on this partnership as we introduce Keto-Mojo to new audiences and accelerate growth across additional markets.”
