E-commerce KPIs can indicate how well your online business is doing in terms of profitability and growth. There are several important KPIs that every ecommerce business should measure and track. CVR - Conversion Rate is one of the most important ecommerce metrics to track the visitors who “take action” on your site. CVR is calculated as a % - customers who either purchase something, click on the ad, sign up or create an account. The higher the conversion rate, the better the result. The average conversion rate is somewhere around 1,9%.
