Engagement Metrics are key performance indicators (KPIs) used to measure customer interactions with a brand. Common metrics include email open rates, click-through rates, social media engagement, time spent on a website, and customer retention rates. Businesses use these metrics to evaluate marketing effectiveness, optimize customer experiences, and refine sales strategies. CRMs and analytics tools like Google Analytics and Marketo track engagement data, providing insights into customer behavior. Understanding engagement metrics helps businesses identify trends, improve content strategies, and increase customer lifetime value.
