WATCH: What is UKOM and how does the data we endorse in Ipsos iris measure and report online audiences in the UK?

“UKOM’s governance continues to drive the industry forward, allowing for an audience-first view of the UK’s online behaviour. Their revolutionary approach has led to industry firsts for insight and reporting. Client trust in media planning is further enhanced with the ability to account for the likes of Sky’s off-platform video and the addition of richer YouTube data.”

Barry Walsh, Digital Strategy Partner, Havas Media

“UKOM’s governance of an industry standard for UK online audience measurement across PC, tablet and smartphone is a key foundation for AOP publishers. Having UKOM-endorsed data from Ipsos iris now available with Ozone in the programmatic space demonstrates how UKOM has remained true to its ambition to evolve with the UK market and allow transparent, objective and agreed audience standards to be applied.”

Richard Reeves, Managing Director, AOP

“With the UK on track to be the first market in the world to exceed 70% of total spend via digital media, UKOM's appointment of Ipsos is a positive step towards measurement of this tremendously complex area.”

Dominic Carter, Group Chief Commercial Officer, News UK

“With Ipsos iris now as its endorsed provider of the UK industry standard for online audience measurement, UKOM is in the best place to face the future. The flexibility of iris to support cross media measurement is a great step forward.”

Jon Mew, CEO, IAB UK

“UKOM provides necessary governance of an industry standard for UK online audience measurement across PC, tablet and smartphone. UKOM’s flexibility has paid off with advances including the inclusion of YouTube data at organisation level and Ipsos iris data now available for the activation of audiences in the programmatic space.”

James Chandler, Chief Marketing Officer, IAB UK

“UKOM-approved data is an important part of the IPA’s TouchPoints Channel Planner, the UK’s only industry-available cross-media channel planner. UKOM’s governance is relied upon for transparency and quality – and as reporting evolves further the data from Ipsos will provide even greater comparability with other data sources.”

Belinda Beeftink, Research Director, IPA

“With its single source panel of 10,000 people and 25,000 devices, Ipsos iris is a great step forward in online audience measurement for UKOM as it pushes the reset button from January 1st 2021.”

Steve Chester, Director of Media, ISBA
