Use this trigger to measure the amount of time a user spends on a page to complete a task (e.g. read an article, fill out a form, or complete a purchase.) To create a new timer trigger: 1. Click **Triggers > New**. 2. Click **Trigger Configuration** and choose the **Timer** trigger type. 3. Add an **Interval** in seconds. The trigger will fire at the specified interval (e.g. every 7 seconds.) 4. Turn on **Trigger Continuously** to fire the event every time the interval is reached until the user leaves the page. 5. In the "**Enable this trigger when all of these conditions are true**" section, specify a ***variable***, ***operator***, and ***value***. This step will ensure that the trigger listener is enabled only when necessary, to help improve overall website performance. 6. Save the trigger and publish the container.
