New PubMatic Research Shows Private Marketplaces Drive Global Mobile Advertising Growth

The Q4 2017 Quarterly Mobile Index (QMI) report affirms continued rise of mobile PMPs as advertisers seek premium, brand-safe inventory programmatically

REDWOOD CITY, Calif. – PubMatic, the publisher-focused sell-side platform (SSP) for an open digital media future, announced findings from its Q4 2017 Quarterly Mobile Index (QMI). The report, which identifies trends in mobile advertising, found that mobile private marketplaces (PMPs) monetized impression volume increased by 37 percent year-over-year (YOY) in Q4 2017, adding to a long growth streak for mobile PMPs now spanning eight consecutive quarters.

“We have seen a profound shift towards supply chain integrity and quality in 2017”

The upswing for mobile PMPs is attributed to major marketers continuing to increase spend through programmatic channels. PMPs offer robust options for advertisers to gain access to premium inventory coupled with safeguards for ad fraud and brand risk, amid growing concerns about quality, viewability and transparency. For publishers, PMPs provide more control over their inventory and partnership with buyers. As a result, mobile PMP eCPMs globally in 2017 were priced at a 155 percent premium, compared to those paid for the average mobile open exchange impression.

“We have seen a profound shift towards supply chain integrity and quality in 2017,” explained Rajeev Goel, co-founder and CEO of PubMatic. “We expect this trend towards quality and programmatic direct to continue in 2018 as advertisers increasingly demand higher standards for transacting. As an industry, we need to continue our efforts in giving buyers access to highly-engaged mobile audiences in a brand safe environment while providing sellers greater visibility and control.”

Additionally, PubMatic’s new report shows mobile header bidding moved into the mainstream and approached maturity at the end of 2017, with global volume growth rates slowing to ‘merely’ robust levels by Q4. Mobile web experienced 121 percent YOY growth in header bidding impression volume in Q4 2017, more closely aligning with desktop inventory, which experienced an 81 percent YOY impression growth rate over the same period. As publishers deepened their header bidding expertise, the popularity of hybrid solutions offering both client- and server-side integrations, such as PubMatic’s OpenWrap, rose from 13.6 percent to 20.7 percent adoption rate between September and December 2017 according to ServerBid.

More highlights from the Q4 2017 Quarterly Mobile Index include:

  • Apps drove mobile volume growth in 2017, while mobile web eCPMs rose more than 50 percent YOY globally.
  • Android built a dominant OS lead to represent roughly eight-in-ten monetized mobile app impressions worldwide in 2017, while iOS delivered higher eCPMs.
  • Header bidding impression volumes monetized via mobile web in 2017 expanded fastest in APAC where they rose 43X YOY, followed by 4X YOY expansion in EMEA and 1.5X in the Americas.
  • Mobile video remained a developing opportunity as its global footprint expanded with mobile video eCPMs catching up to desktop in 2017.
