Data-Driven Media Planning for Brands Competing on the International Stage

One Day is a full-funnel media planning and buying agency with colleagues based throughout the UK and Europe, working within these regions and the US, APAC, the Middle East and beyond. We deliver professional, strategic support for brands that need consistency in their cross-market campaigns.

Our focus is on developing media plans based on data, analytics, and insights. This ensures your advertising initiatives align with localised market conditions and audience behaviours while linking back to your brands’ global objectives, with access to digital, social, broadcast, and out-of-home placements.

The Benefits of Strategic International Media Planning

Advanced media planning goes far beyond channel selection. It requires thorough knowledge of every variable that will determine whether international campaigns achieve sustained success or fall flat. It also builds on expertise and accurate data to ensure marketing is tailored to deliver the right relevance and context.

Our years of experience and global reach mean we can advise on the cultural norms and nuances, market positioning, regional competition, audience trends and behaviours and seasonality relevant to each region you want to target.

Working With One Day on International Media Planning

With sector-specific niche expertise across FMCG, B2B, retail, tourism, tech, and software, our teams throughout Europe and the US have worked in all the world’s major markets and support brands looking to enter new regions and achieve international expansion.

Cross-marketing plans integrate digital and conventional channels to ensure performance and returns are measurable and consistent, with scalability built in from day one, so high-impact campaigns can be quickly rolled out across additional channels or locations.

“International media planning only works when it respects how people actually consume media in each market, not when it’s copy-pasted across borders. Most brands still plan centrally with local compromises; the advantage comes from specialists who understand cultural behaviour, channel nuance, and scale without losing relevance.”
