You have many events on your website that are highly valuable, like when users purchase items or sign up for your newsletter. You'd like to mark these events as important. What should you mark these events as in your Google Analytics property?

Key events are events that measure actions especially important to a business. They are used to highlight valuable user interactions such as purchases, sign-ups, or other priority actions. Marking events this way makes them easier to analyze in Google Analytics reports. These events can also support advertising conversion workflows when linked products are configured.
