Abstract

We explore the idea that market-shares of any given company have a linear relationship with the number of times the company/product is searched for on the internet. This relationship is critical in deducing whether the funds spent by a firm on advertisements have been fruitful in increasing the market-share of the company. To deduce the expenditure on advertisement, we consider google-trends as a replacement resource. We propose a novel regression algorithm, generalized Dirichlet regression, to solve the resulting problem with information from three different information-technology fields: internet browsers, mobile phones and social networks. Our algorithm is compared to Dirichlet regression and ordinary-least-squares regression with compositional transformations. Our results show both the relationship between market-shares and google-trends, and the efficiency of generalized Dirichlet regression model.
