Strategic Decision Making of Social Media Marketing Professionals under Platform Uncertainty: A Study of Meta Ads Performance Volatility

The rapid evolution of Meta's advertising ecosystem — encompassing Facebook, Instagram, and Messenger — has introduced unprecedented levels of performance volatility, compelling social media marketing professionals to adopt dynamic and adaptive decision-making strategies. This paper examines the strategic responses of marketing practitioners to three core dimensions of platform uncertainty: algorithm-driven ad delivery inconsistencies, persistent ROI unpredictability, and the escalating cost-per-impression (CPM) environment induced by auction inflation and privacy-driven data loss. Drawing on secondary data from Meta's quarterly earnings reports (Q3 2023–Q1 2026), industry analytics from GeistM, Coinis, Right Side Up, and Varos, alongside peer-reviewed academic studies, this article constructs a structured analytical framework for understanding how professionals adapt, respond, and survive in an era of opaque platform dynamics. Findings indicate that cost-per-lead climbed 21% year-over-year in 2025, CPMs spiked up to 66% during peak e-commerce seasons, and average Meta ad costs grew 14% against only a 6% increase in impressions. These dynamics fundamentally reshape the strategic toolkit of the modern social media marketer, necessitating creative diversification, signal-based targeting, and agile budget management.
