The mobile advertising landscape is experiencing rapid change and growth. With the rise of smartphone use and technologies to better serve and track mobile ads, we’ve seen an explosion in the amount of money being spent on mobile advertising over the past few years and that trend is only expected to continue. Gartner Research estimates that global mobile advertising spend was $13.1 billion USD in 2013 and is projected to rise to almost $42 billion USD by 2017.

Of the estimated $13.1 billion spent on mobile advertising in 2013, Facebook accounted for $3.28B or approximately 25%. There’s no doubt Facebook plays a major role in mobile marketers budgets and strategies. But, with that said, there are hundreds of other mobile advertising players who collectively make up the other 75% of the mobile advertising pie.

With Mobile World Congress in session, we wanted to take a moment to point out who some of the major players are in this 75% and show our support for their growing businesses. It is our mission to provide transparent, unbiased technology that allows these companies to more easily work with their clients and continue to expand the mobile ad industry.

How did we determine the rankings?

With over 375 integrated partners on MobileAppTracking, we wanted to point out the top 25 based on three equally weighted factors (Revenue Per Install, Install Volume, and Client Adoption). To be clear, this is only their size and performance related to MobileAppTracking and does not account for their business that exists on their own or other platforms. While we are the first to admit that this ranking methodology isn’t perfect, it is a strong indicator of the platforms and partners making major waves, and checking this list against market trends does suggest significant relevance.
