Events let you capture and monitor every interaction made by a user. In Contentstack Personalize, there are two types of events: Impressions and Conversions.
Impressions: Impressions are a way to count how many times users see specific content on your website.
Conversions: A conversion is an event that signifies a positive user action, such as adding a product to the cart, making a purchase, or scrolling to the end of a page. Conversions are essential for measuring the success of your A/B tests.
