In the ever-competitive telecommunications landscape, acquiring new customers hinges on identifying their precise locations. This study investigates how Pakistan's leading telecommunications provider, PTCL, employed an innovative geo-marketing approach to pinpoint optimal locations for new customer service centers in Islamabad. The study integrates advanced GIS-based spatial analysis with statistical techniques, such as geographically weighted regression (GWR), achieving an adjusted R2 of over 0.75 in predicting potential customer density. Unique to this work is the incorporation of multidimensional datasets, including demographic, economic, and competitive factors, coupled with tailored site selection criteria to optimize accessibility, visibility, and resource allocation. By leveraging this novel approach, PTCL enhanced targeting efficiency and strategic decision-making, gaining a stronger competitive market position. This study highlights the transformative potential of data-driven geo-marketing in emerging markets, providing actionable insights for telecommunications companies aiming to optimize customer acquisition strategies.
