Search Engine Optimization (SEO) vs. Pay-Per-Click (PPC): A Comparative Study of ROI for Small Businesses

Abstract

Small businesses increasingly depend on digital marketing to remain competitive in saturated online marketplaces. Among the most widely adopted strategies are Search Engine Optimization (SEO) and Pay-Per-Click (PPC) advertising. While both approaches aim to increase visibility and drive customer acquisition, they differ significantly in cost structure, timeline, and sustainability. This study critically examines the return on investment (ROI) associated with SEO and PPC to determine which strategy offers stronger financial value for small businesses. Drawing upon academic literature and comparative performance data, the findings suggest that PPC is highly effective for generating immediate traffic, whereas SEO provides more stable and cost-efficient returns over the long term.
