The MMA and its MATT initiative have been working for over 2 years to better understand multi-touch attribution (MTA) and how to help marketers improve measurement and attribution of marketing campaigns. MATT conducted several studies measuring real campaigns and found that optimizing campaigns by including mobile often increased key metrics like sales by over 10%. MATT also found that targeting and personalizing mobile campaigns could further increase metrics by hundreds of percent. However, MTA is complex with many possible format, data, and targeting combinations to test. MATT aims to provide guidance to help marketers choose the right MTA providers and solutions.
