Performance Marketing refers to a form of digital marketing where advertisers pay for specific actions or outcomes, rather than paying for ad space or impressions. This model emphasizes measurable results, such as clicks, conversions, or sales, and often includes methods like pay-per-click (PPC), affiliate marketing, and cost-per-action (CPA) campaigns. The goal of performance marketing is to optimize advertising spend by ensuring that every dollar invested directly contributes to a quantifiable return on investment (ROI).
