Calendar Q4 2017 Report Highlights Quality Trends and Best Practices Based on Data from RhythmOne’s Programmatic Platform

London, England and San Francisco, CA. — 27 February 2018 – RhythmOne plc (LSE AIM:RTHM), a global advertising technology company, today announces the release of the Q4 2017 installment of its “Programmatic Insights Report – Spotlight on Quality” series. Based on an analysis of the 2.8 trillion average monthly ad opportunities RhythmOne’s programmatic platform processed from October to December 2017, the report provides insight into quality trends and invalid traffic (IVT) blocking rates by device, type, and ad size. This is the series’ first global update; included within are breakouts for North America (US and Canada), the UK, and Europe.

Leveraging RhythmGuard, RhythmOne’s proprietary brand safety technology that filters underperforming or suspicious traffic before it reaches the marketplace, the report provides a unique perspective about where and why quality shifts are occurring across its significant supply footprint, and offers guidance to advertisers and brands when designing their advertising programs and measuring success.

Summary of Q4 2017 Findings and Insights

  • Across the globe by type, RhythmOne’s average blocking rate for video advertising slightly edged out banner advertising (49% vs. 45%)
  • Inventory on desktop devices (56% of overall ad opportunities) was blocked at a higher rate than mobile devices (38%)
  • IVT blocking on the mobile web (56%) and mobile app (27%) showed some month-to-month fluctuation
  • The blocking rates by respective advertisement size, for both banners and video, were consistent from month to month (with minor fluctuations) among North America, the UK, and Europe
  • Enabling contextual blocking tactics that go “beyond the URL” further ensures brand safety at the page level
  • Running campaigns in Private Marketplaces promotes a high-quality and transparent environment with greater control over placement

“Quality traffic and brand safety are top-of-mind for advertisers,” said James Murphy, VP, Programmatic at RhythmOne. “Our latest quarterly Programmatic Insights report provides clarity into how and where we’re addressing inventory quality within our marketplace. The quarterly series reaffirms our commitment to transparency within the supply chain. I’m especially excited that we have expanded our report to include global data that will empower our partners worldwide with trends to better understand the dynamics of delivering quality supply.”
