Using econometrics to shape marketing investment


The rise of digital platforms and channels has led to a fundamental shift in how brands should allocate their marketing budgets. In today’s Ecosystem, there are more links in the media supply chain than ever, and more ways for brands to interact with customers. The established norm of using golden ratios – such as the often used 80/20 rule for working and non-working media allocation – has had its day. Instead, advertisers now have all of the tools available to build their marketing plans from the ground up, based on overarching business objectives, using data and evidence to guide investment decisions. As a result, brands should now move beyond simplistic approaches to budget allocation, the most common being fixed ratio targets for working versus non-working media.
