Here is a neutral and interesting summary of the provided text in one paragraph: To understand how effectively businesses engage with customers across multiple channels, tracking digital customer engagement metrics is crucial. Customer engagement refers to interactions between a business and its customers that build relationships and foster loyalty. Website metrics such as average session duration, pages per session, engagement rate, bounce rate, and conversion rate help gauge the effectiveness of a website in keeping users engaged. Marketing metrics like click-through rate (CTR) and social media engagement rate measure the success of marketing campaigns. Customer experience metrics including customer satisfaction score (CSAT), net promoter score (NPS), customer retention rate, and customer churn rate provide insight into how customers feel about their interactions with a business. A contact center platform that enables personalized engagement across channels is essential to improve customer engagement, and tools like Twilio Flex can help businesses track and improve their metrics to drive better customer relationships.
