What does CR (conversion rate) mean?

CR, or conversion rate, expresses what percentage of users or visits performed the desired action. In e-commerce, it is most often completing an order, but it can also be registering, submitting a form, signing up for a newsletter or another important step. It is usually calculated as the number of conversions divided by the number of visitors or visits, multiplied by one hundred. For example, if 30 out of 1,000 visitors make a purchase, the conversion rate is 3%. This metric helps evaluate the effectiveness of a website, campaigns and the purchase process and reveal room for optimization.
