Triggers

Use this page to choose a trigger type and narrow it with conditions. A trigger decides when a tag fires. Attach one or more triggers to a tag under Firing Triggers; one trigger can be reused by many tags.

Trigger types

Page lifecycle

• Page View: every page load. Add a URL condition to limit it to certain pages.
• Initialization, DOM Ready, Window Loaded: earlier or later points in the same page load.
• History Change: the URL changes without a full reload, as in a single-page app.
• Window Leave and Window Unload: the visitor is about to leave, or the page is closing.

Interactions

• All Elements Click, All Links Click, All Downloads Click: a click on any element, a link, or a link to a downloadable file.
• Form Submit: a form is submitted. Turn on Check Validation to skip submissions your site cancels, for example when client-side validation fails. All Links Click has the same option for clicks.
• Element Visibility: a matching element comes into view.
• Scroll Reach: the visitor reaches a vertical or horizontal depth you set.
• User Interaction, Fullscreen, JavaScript Error, Timer.

Your code

• Custom Event: your code pushes an event with a matching name to the data layer. Use it for anything the other types cannot see, such as forms that send data in the background.

Consent

• Consent: First Consent, Consent: Change, Consent: Loaded, and the modal events. Use these to fire tags when a visitor accepts a category.

Each type's options are described in the trigger editor.

Conditions

Add conditions to any trigger to fire only when they all match. A condition compares a variable to a value: Page Path contains /checkout, Click Element ID equals buy-now, or a Consent: Category variable equals true. Click triggers also accept matches CSS selector and does not match CSS selector.
