ironSource's Industry eCPM Index acts like the Nasdaq for the app economy

Our work with eighty thousand apps across the world, who collectively reach nearly a billion unique users a month, lends us exceptional insight into global app economy health. With the industry eCPM Index, we wanted to make this insight widely available.

Global technology powerhouse ironSource today announced the launch of its Industry eCPM Index, an insights engine for tracking regional and global eCPM rates and optimizing mobile app ad campaign effectiveness over time.

Ideal for mobile app developers, the ironSource Industry eCPM Index provides insight into app ecosystem advertising performance across region, time of year, geography, ad units, and operating systems. The index is powered by a sophisticated algorithm that analyzes the changes in effective cost per thousand in-app ad impressions across each of these categories, enabling developers to understand overall app ecosystem trends.

“Our work with eighty thousand apps across the world, who collectively reach nearly a billion unique users a month, lends us exceptional insight into global app economy health,” said Tal Shoham, VP International Business Development, Developer Solutions, ironSource. “With the launch of the Industry eCPM Index, we wanted to make this insight available to developers everywhere, empowering them to identify high-performing ad units, track industry trends, and drive additional revenue. Ideally the index will serve in the long-term as a stock market-like tool to give anyone in the mobile app ecosystem valuable, up-to-date app economy insights.”

Available to a small group of select developers throughout 2016, today’s launch marks the index’s availability for the mobile developer and advertising community at large. In sync with the launch, ironSource is releasing key insights from the index from its full year 2016 tracking study, or 2016 eCPM Year in Review. Among the findings:

Gap in Ad Units - The eCPM of Rewarded Video ads showed consistently high growth in 2016, while the eCPM of Interstitial ads showed much more moderate growth. This was reflected in a widening gap between the eCPMs of both ad units. The gap between RV and Interstitial ad units on Android devices widened by 70%, while on iOS the the gap increased by 40%.

Gap in Platforms - The gap in eCPMs between iOS and Android across ad units decreased by more than 20% last year, as demand for Android users increased. Advertisers are increasingly willing to pay more to reach audiences on Android, revealing a shrinking difference between the value of iOS and Android audiences.

Regional Growth & Volatility - Looking across ad units, the eCPM of North America had the highest growth rate (35%), followed by the EU (30%) and then emerging markets (10%). It’s also worth noting that the eCPM of emerging markets is more volatile in comparison to North America and Europe.

Growth Patterns - Throughout the year a few events have impacted eCPMs across regions:

The launch of the iPhone 7 in September correlated with a rise in the eCPM on iOS, likely due to an influx of advertisers who wanted to capitalize on this opportunity.

At the end of each quarter the Index detected a sharper rise in eCPM, likely due to the fact that advertisers usually want to finish their budgets towards the end of the quarter.

As expected, the holiday season created a rise in eCPM due to increasing demand for mobile traffic.

During August and September sophisticated performance advertisers started to buy on a CPV basis, creating notable growth in the eCPM of Rewarded Video.

The methodology behind the eCPM Index discards publishers that do not achieve a certain traffic threshold, in order to prevent a biased outcome. The eCPM index is updated every month to reflect fluctuating eCPM growth and decline across regions, ad units, and operating systems.
