Tracking sales and customer behavior on your eCommerce website is essential to understanding your customers' needs and preferences and improving your website's performance. One way to track this information is by using Google Analytics, a free web analytics service that provides detailed information about website traffic, user behavior, and conversion rates. Google Analytics allows you to track key performance indicators such as page views, bounce rates, and average session duration, as well as conversion goals such as purchases and form submissions. Additionally, you can set up e-commerce tracking to monitor sales and revenue. By analyzing this data, you can make informed decisions about website improvements, marketing strategies, and product offerings to better serve your customers and grow your business.
