Mobile is the greatest transformation in consumer behavior and will have a profound impact on businesses. Empirical research from MMA's SMoX studies across multiple brands and countries found that allocating 12-20% of advertising budgets to mobile marketing can increase key metrics like awareness, purchase intent, and sales by 7-60%, especially when best practices are used. As smartphone adoption increases to over 90% of the population, the optimal allocation to mobile may rise to 20-30% of budgets. Marketers are challenged to understand how to effectively utilize mobile's unique ability to reach consumers closely and optimize their mobile marketing strategies.
