Custom Events: Custom events are user-defined tracking actions in web analytics or marketing automation tools that help you measure specific user interactions, behaviors, or activities on your website. Unlike standard events, which are predefined by the tool (e.g., page views, clicks), custom events provide more flexibility and allow you to track unique actions relevant to your business, like watching a video, adding a product to the cart, or signing up for a newsletter. By setting up custom events, you can gather more insightful data and optimize your marketing campaigns based on user behavior.
