Performance marketing is a digital marketing strategy that involves paying for specific outcomes, such as clicks, leads, or sales, instead of paying for exposure or reach. This allows advertisers to optimize their campaigns and increase ROI. Performance marketing can be implemented through various channels, including search engines, social media, websites, and apps. Pay-per-click (PPC) marketing is another type of performance marketing where advertisers charge a fee for each click their ads receive on search engines or other platforms. Cost-per-action (CPA) marketing involves paying for completed actions, such as filling out a form or making a purchase after users click on ads. Cost-per-mile (CPM) marketing involves paying for every thousand impressions an ad receives on a platform.
