One Day Agency has been appointed to manage Keto-Mojo’s marketing in the UK, alongside further expansion into 21 countries. The expanded work follows positive early results across the six European markets already managed by the agency.
The health technology brand began working with One Day in May 2026, initially appointing the agency to manage performance marketing across Germany, France, Poland, the Netherlands, Ireland and Austria.
Keto-Mojo specialises in blood ketone and glucose monitoring devices, empowering consumers to better understand and manage their metabolic health. The brand serves customers internationally, including individuals following ketogenic lifestyles, managing diabetes, pursuing weight loss goals, and using biomarker data to make informed decisions about their health and nutrition.
The expansion brings paid search, paid social and creative development together under a broader international strategy. One Day will work closely with Keto-Mojo’s internal marketing team to adapt campaigns for different audiences and identify opportunities across the additional territories.
The approach builds on the agency’s experience across the original six markets, where campaigns combine Google Search, Shopping and Performance Max with Facebook and Instagram advertising. Creative concepts and video content are tailored to individual countries, reflecting local audiences while maintaining a consistent brand identity.

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.”
As the work expands, search-demand research and customer journey analysis will help guide investment and campaign planning. The wider strategy also includes channel diversification and market-specific activity around key periods such as 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.”
New work extends One Day’s role beyond paid media management, combining creative production with strategic consultancy and ecommerce analysis to support Keto-Mojo’s international plans.
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.”
