Harnessing Multi-Armed Bandits for Smarter Digital Marketing Decisions

In the current digital age, software programs and applications provide convenience and added value in a number of ways. Multi-armed Bandit algorithms (MAB) are a prime example of this; In capital markets, they assist in the adaptive design of trading strategies that adjust to market shifts and investor behavior. In e-commerce, MAB helps optimize product recommendations by learning customer preferences in real-time. In SaaS, MAB can optimize user experience by personalizing services or pricing models based on user behavior, continuously adjusting to maximize engagement or revenue. In cloud engineering MAB are indispensable for optimizing resource allocation based on user demand. The objective of this paper is to demonstrate the adaptability of MAB algorithms through an examination of their applications, specifically focusing on the Digital Marketing domain and the insight they offer for optimal decision-making. The article highlights the usefulness of major MAB algorithms in digital advertising, e-commerce content suggestion, SaaS and strategic pricing by carefully examining Thompson Sampling, UCB, Restless Bandit, and Structured Bandit as key types of MAB algorithms. The study emphasizes how these algorithms adjust to fluctuating conditions, balance a trade-off between exploration and exploitation, and eventually improve marketing strategies. This article aims to improve knowledge of MAB algorithms and encourage more research in this promising area by providing a detailed analysis of their applications.
