Smartphone now accounts for half of all UK digital ad spend

Apr 24, 2019 | Ads, Mobile, Search engine marketing, Video

UK advertisers spent £13.44bn on digital advertising in 2018, marking a 15% year-on-year increase, according to new research.

The latest IAB UK and PwC Digital Adspend study demonstrates continued confidence in the power of digital advertising.

For the first time ever, ad spend on smartphones has exceeded desktop accounting for 51 percent of the total spend, up from 45 percent in 2017. This is a year-on-year increase of £1.65bn.

These latest figures show that advertising spend now better reflects consumer behaviour, with recent UKOM audience data showing that people spend two thirds of their online time on smartphone1.

Beyond mobile, an additional driver of growth continues to be video, which accounts for 44 percent of the total display market. For the second year running, outstream has exceeded pre-roll video2, accounting for 57 percent of all video advertising.

In addition, the figures show that companies fully certified for the IAB UK Gold Standard outperformed the total display market, seeing a 30 percent year-on-year increase in ad spend revenue versus 22 percent overall.

The results are bolstered by new YouGov research3 commissioned by IAB UK showing that nearly two thirds (64%) of marketing decision makers, with responsibility for online video advertising, agree that online video assets should be made bespoke for the platform or device they are shown on. Furthermore, the research confirms that more than half of marketers use online advertising for longer-term brand building, not just short-term sales activation.

Commenting on the results, Tim Elkington, Chief Digital Officer, IAB UK, said “seeing mobile now account for over half of all digital ad spend is a significant milestone. In a decade of reporting these figures separately, we’ve seen spend rise from £38m in 2009 to a staggering £6.88bn in 2018.”

Jon Mew, CEO, IAB UK, continued, “alongside increased investment from leading advertisers, digital advertising remains an accessible route to market for SMEs. We continue to see evidence of online advertising being used for brand-building, especially by the growing market of direct to consumer (DTC) brands.”
