Websites have different goals, e.g. providing information, selling goods, generating revenue or simply entertaining visitors. With an evaluation of your set conversion goals, you can regularly analyze whether you have achieved them. For example, if you sell products online, you can evaluate the number of sales after each visit to your website. If you provide your users with purely informative content, you can analyze your conversion based on the number of visitors to your website. The conversion always provides you with information about the current status of your set goals and you can still optimize here if necessary.
