Most companies traditionally allocated advertising budgets to different channels like TV, print, radio, and online ads independently. However, new data and analytics show that advertising channels interact with each other and are more effective when coordinated. Analytics 2.0 uses predictive tools and large data sets to quantify the contribution of each advertising element, run optimization scenarios to test different channel combinations, and enable real-time allocation of resources across channels based on what will be most effective. Proper implementation of Analytics 2.0 requires organizational change, data collection across marketing and business metrics, starting with small tests, and continuous improvement of models.
