Over the course of 2014, there were significant changes in terms of revenue and traffic generated across the two leading device operating systems — Android and iOS. Foremost, Android overtook iOS in ad impressions served and now dominates the market by this measure.
The evolution shown here is occurring within a rapidly growing market; smart device adoption has grown exponentially and traffic volumes are 3.5 times what they were four years ago.
As 2014 drew to a close, more than 6 in 10 ad impressions were served on Android phones, with almost 3 in 10 served on iPhones, and the rest on Symbian, Windows and BlackBerry, among others.
In Q3, we observed that Android was beginning to close the gap in revenue, rising to nearly 42% of revenue compared to iOS’s 51.2%. In Q4, though, that trend did not continue, and we can see Android’s revenue share (41.2%) and iOS’s share (51.7%) comparable to the previous quarter, showing stabilization, with iOS maintaining a clear lead.
iPad monetization has also stabilized, back down to its Q4 norm of between 12 and 13%, which is high considering it has a mere 5% share of impressions. The previous quarter saw a lifetime peak at more than 17% of revenue with under 7% of impressions. So, the iPad continues to show remarkable monetization capabilities.
Over the past few years three categories of mobile sites and applications have been clear leaders in traffic volume and revenue generation:
- Social Networking
- Music, Video & Media
Though these categories sometimes change their relative positions, or on occasion, get displaced by another category — they continue to be the key categories of mobile media consumption.
More impressive, however, is its growth in production of revenue. In December 2013, Games represented less than 3% of revenue on the platform. By December 2014, the category produced nearly 24% of revenue and is now in a virtual dead heat with Music, Video & Media for the top spot.
Taking a step back and looking at year-over-year data, we can see that within these three categories, Games is the big success story in 2014. As the graph shows, gaming sites and apps represented just 5% of our impression volume in 2013 but has jumped to nearly 14% this quarter.
Over the past few years, however, non-U.S. markets began to capture more share, and we witnessed a true “globalization” of mobile advertising. At first (2011-2012), it seemed that Europe was the fastest growing market, but it soon became apparent that Asia Pacific countries were accelerating at a faster pace.
By the end of 2014, we also see the Americas (non-U.S.) and Africa catching up somewhat to start playing a larger role within the international market, with 9.8% and 4.8% respectively. Africa’s growth, up from just 1% in 2013, is the most notable.
And yet, despite the globalization trend, the United States still drives the greatest share of both traffic and revenue.
To be successful, mobile websites and applications must continually acquire and retain users. In today’s diverse mobile marketplace, this is neither simple to plan for nor easy to accomplish. Even if successful in obtaining users with a call to action that drives a download or visit, users inevitably churn off (no longer use) the application or visit the site, or reduce the frequency of their use. As shown on the chart below (derived from a single example), the loss of initial users can be rapid and large.
However, while rates to acquire the customer are stable or declining, the number of impressions required to win a new customer is increasing, thus reducing the effective revenue (cost) per impression (eCPM) achieved by the media property (app or site) displaying the performance campaign.
The impact of this declining eCPM from CPI campaigns is that average brand advertising eCPMs are at least equal to performance rates, and brand advertisers can now win impressions away from performance advertisers.
These and others observations from our traffic imply some potential keys to success for user acquisition and monetization with applications.A mere analysis of average cost disguises the critical factor of session depth. Performance campaigns (e.g., CPI campaigns for games) can generate significantly higher rates of installations – and therefore eCPM – when the impression i
