Cross-device audience ID matching will be used in 58% of total UK online ad spend by 2020, compared with 28% in 2016, according to a new report from Yahoo and Enders Analysis. These ‘audience IDs’ are the online identity profiles created from anonymous identifiers in order to recognise and match the same user across different channels, devices or both.

The report, People, not devices: Audience buying in a Cross-Device World, shows that ad spend based on audience IDs will almost triple in the next few years, reaching €7.9 billion by 2020, compared with €2.7 billion in 2016. The trajectory to growth will see this ad spend reach €4.33 billion in 2017, before hitting €6.22 billion in 2018 – a 226% increase from last year.

When the General Data Protection Regulation (GDPR) comes into effect in 2018, growth in the volume of ad spend which uses audience IDs will slow down, as the advertising industry works to ensure compliance with the new regulations. It will, however, continue to grow, as the industry responds and adapts to the new regulatory requirements.

By 2020, the proportion of display ad spend that uses audience IDs will be slightly higher than for paid search, accounting for an estimated 68% of display spend, compared with 55% of paid search. Most of this growth will come from mobile display and mobile search growth.

The report attributes a large portion of future growth to the recognition from advertisers that using audience IDs will give them a better picture of who is seeing their ads across devices, the ability to better understand and manage frequency exposure and more accurate information about total campaign reach. In addition, cross-device ID based advertising allows for improved attribution, as these IDs can be used to attribute purchases and conversions to show concrete ROI for campaigns.

Nigel Clarkson, managing director, Yahoo UK says “In a world where the number of connected devices per person is increasing at pace, cross-device campaigns should be the norm. Yahoo is already enabling these kinds of campaign, with datasets across search, email and social that allow us to accurately match 89% of users across devices. This level of insight benefits consumers as well as brands and advertisers as it helps get the right message in front of the right audience, making it a win for all.”

Matti Littunen, senior research analyst, Enders Analysis adds “Providing an interface between media, marketing, retail and services, audience IDs are at the heart of the data economy and increasingly important for the online consumer experience. In advertising, they have promise in addressing perhaps the single biggest issue of a changing industry: how to accurately attribute value to ads in a complex online media market? 2017 will be the year media owners, advertisers and agencies come to terms with the full significance of audience IDs.” ()

The use of audience IDs allows marketers to get closer to the notion of having a ‘single view’ of the consumer. Data from loyalty programmes, payment technologies, beacons, ecommerce and in-app trackers can be connected with the IDs used to serve ads, and attribute purchases to prior ad views, further bolstering the importance of audience IDs in the coming years according to the report.

The appeal of cross-device IDs is further increased by the problems of fraud and non-human traffic in online advertising. While not a complete solution, cross-device audience buying at its best can help distinguish between real and fake ad views, and help test claims of ad effectiveness.

Consumers also stand to gain from the growing use of audience IDs. A more sophisticated understanding of the consumer will mean individuals are shown more relevant advertising, that’s less intrusive, as advertisers will be better able to tailor both the creative and delivery methods. This will also mean lower overall ad loads, as the ability to better measure the number of times a consumer sees a particular ad across all of their devices will enable ‘frequency capping’.

We use the term “cross-device audience buying” to refer to all advertising which makes use of IDs advanced enough to identify the same audience segment on multiple devices with a high degree of accuracy.
