Connecting Online & Offline Marketing Performance

Tesco Ireland needed one connected view of marketing performance across digital and traditional media. We unified reporting, standardised measurement and enabled faster, data-driven decisions.

Client Overview & Challenge

Tesco Ireland operates across a highly complex media landscape, spanning both digital and traditional channels. While digital performance was measurable in-platform, offline activity such as TV, radio, OOH and press was reported separately, resulting in a fragmented view of performance.

Reporting typically sat across individual teams and agencies, leading to inconsistencies in KPIs, naming conventions and overall reporting methodologies. Previous attempts to bring this data together often resulted in static, point-in-time dashboards that quickly became outdated, limiting both adoption and long-term value. At the same time, a lack of shared visibility created challenges across agency partners, with no single view of performance across the full media mix.

Tesco Ireland needed a partner to bring together all live online data into a single, connected environment, while also creating a scalable, long-term solution for integrating offline media. Crucially, this needed to align to their internal KPIs, brand metrics and campaign structures, while enabling teams to assess performance in real time and make more informed, cross-channel decisions.

Our Strategic Approach

We approached this as a data and measurement challenge first, not just a report build. Our objective was to create a single, trusted measurement layer that reflected how the business operates and makes decisions.

Single Source of Truth

Worked closely with internal teams and agency partners to map all data sources, bringing together live online platforms and structured offline inputs into a single, connected dashboard.

Consistent Measurement Framework

Collaborated with stakeholders to define a standardised KPI framework, aligning naming conventions, campaign structures and metrics to Tesco Ireland’s internal taxonomy and business objectives.

Real-Time Decision Making

Designed the dashboard as a live performance tool, enabling teams to assess performance in real time and make real-time optimisation decisions rather than relying on retrospective reporting.

Transparency & Cross-Agency Alignment

Created a shared performance view accessible to internal teams and agency partners, improving alignment, visibility, and trust across all stakeholders.
