Industry leading stakeholders have set out to eradicate suspect impressions on a global level throughout the past year, and premium publishers and advertisers have begun to feel the impact of this industry shift to quality. Our Q4 2015 Quarterly Mobile Index (QMI) report, released today, shows that advertisers are directing ad spending towards higher-quality inventory with better targeting capabilities, especially through more transparent mobile private marketplaces (PMPs). As a result, premium publishers are garnering higher prices for their inventory and attracting more mobile ad spending.

This past holiday season, major brand advertisers looked to target mobile consumers with relevant advertising messages through mobile private marketplaces (PMP). This dynamic caused a 45 percent increase in weekly mobile PMP volume from the first week of the quarter through to the week of Black Friday. Looking ahead, the volume spikes in mobile PMP during Black Friday and Cyber Monday suggest similar rises in mobile ad prices and spending around this year’s landmark events, including the 2016 presidential election and major sporting events. Agencies looking to effectively execute on their advertiser clients’ strategic plans around major events should look to PMPs to buy timely, premium inventory, at scale.

The market opportunity in PMPs is significant, as eMarketer estimates that ad spending on PMPs in the U.S. will reach $3.65 billion this year, up from just $80 million in 2013. Globally, MAGNA GLOBAL projects that programmatic spending, which includes open auction, PMP and automated guaranteed, will rise to $37 billion by 2019.

PubMatic’s Q4 2015 Quarterly Mobile Index (QMI) report found five key trends that demonstrate mobile monetization growth:

1. Advertiser demand shifts towards higher-quality mobile PMP inventory to target mobile-obsessed holiday shoppers. Advertisers increasingly sought higher-quality mobile inventory to target holiday shoppers on mobile devices, as evidenced by mobile private marketplace volume spikes. Weekly mobile PMP monetized impression volume increased 45 percent from the start of the quarter through the week of Black Friday (Nov. 27).
2. By vertical, retail and technology spending drove PMP growth. Within mobile private marketplaces, the retail and technology verticals showed major volume gains ahead of Black Friday shopping, demonstrating that e-commerce and consumer technology sales likely drove ad spending. The increase in weekly PMP volume in retail and technology over that period was even higher, at 106% and 285%, respectively.
3. Opportunity for mobile growth remains strong on a global scale. The Americas and Europe, Middle East and Africa (EMEA) represented the largest opportunities in terms of volume, but the Asia Pacific (APAC) region was the fastest-growing mobile opportunity.
4. The Android app ad awakens. Android app ads increased the most in terms of both price and volume, while CPMS increased across all mobile platforms, including IOS app, mobile web and tablet web.
5. Mobile gap remains closed. Mobile CPMs are still higher than desktop CPMs, and both mobile and desktop CPMs grew a healthy 36% year-over-year.
