# Overview

You can use custom events to measure user behavior during experiments that are not covered by built-in metrics. Events can be managed in the [Events Manager](https://app.intelligems.io/events-manager).

There are two broad categories of custom events: those that measure page visits, and those that measure other user interactions on the site.

## Page visits

These events measure or filter to visitors who visited specific pages. Because they use Intelligems’ built-in page view tracking, they’re available retroactively, and can be added to experiments even after they’ve been started.

## User Interaction

These events measure user interactions on your site — for example, clicks or scrolls on a page. Targeted elements (for example for a click or "Element Visible" event) do not necessarily need to be available when the page initially loads, they can be created dynamically afterwards (for example, by an app).
