To measure customer engagement, focus on various key metrics: Engagement Rate, which includes interactions such as likes, shares, and comments; Website Traffic, tracking visits and page views; Email Open and Click Rates, which reflect engagement with your communications; and Customer Retention Rates, which measure how effectively you retain customers over time. Additionally, the Net Promoter Score (NPS) helps gauge customer loyalty and satisfaction, while Customer Lifetime Value (CLV) calculates the total revenue expected from a customer. OptCulture offers a comprehensive solution to track all key metrics.
