Redwood City, CA (November 14, 2017) — PubMatic, the publisher-focused sell-side platform (SSP) for an open digital media future, today announced findings from its Q3 2017 Quarterly Mobile Index (QMI). The report, which identifies trends in mobile advertising, found that header bidding continued to thrive worldwide as more publishers replace the old auction waterfall system with this solution. Mobile PMP impression volume in PubMatic’s platform rose 75 percent year-over-year (YOY) in Q3 2017, making it the seventh annual improvement in as many quarters. Desktop remained strong in the overall picture as app monetization still provided the largest mobile advertising opportunity. The volume split between app and mobile web environments normalized after six quarters of market rebalancing.

Mobile continued to drive header bidding growth with a 252 percent year-over-year increase in mobile web impression volume in Q3 2017. This trend is indicative of the need for wrapper solutions like PubMatic’s OpenWrap that empowers publishers to utilize a holistic approach of both client and server-side across formats, including mobile web and in-app. Publishers can use header bidding to improve their mobile monetization while retaining control of their user experience and performance.

“Mobile, once regarded as the third screen is now quickly becoming the first screen for many consumers globally which has accelerated header bidding on mobile,” said Rajeev Goel, co-founder and CEO at PubMatic. “Publishers should be in control of their ad decisioning and those looking to take advantage of both server-side and client-side header bidding should implement a single, holistic wrapper solution to avoid the limitations of a multi-wrapper solution.”

Video, which is designed for higher consumer engagement, made a strong showing as mobile opportunities remained on the upswing. Nearly one-quarter of monetized video impressions in PubMatic’s platform were served on mobile devices in Q3 2017. Crucially for publishers’ video strategy, mobile video eCPMs earned an 8 percent premium over the average eCPMs paid for desktop video impressions during the same quarter.

More highlights from the Q3 2017 Quarterly Mobile Index include:

• Monetized header bidding impression volume rose by 220 percent YOY in Q3 2017.
• Average eCPMs in the mobile PMP channel rose by 153 percent YOY in Q3 2017.
• EMEA and APAC were the catalysts of mobile web header bidding growth with the regions’ shares of total monetized impression volume increasing to 28 and 18 percent, respectively, in Q3 2017.
• Retail publishers saw mobile web impressions rise at a double-digit clip during the 2017 Back-to-School season.
