A page scroll trigger fires a tag when a visitor scrolls down to some point on the page. By default, the tag fires on all pages, but you can adjust its conditions so that the tag fires for a certain page.

You can choose from the following conditions:
- Amount of page scrolled: Fires when a visitor scrolls to the chosen point on the page. For example, a visitor scrolls 50% of the page or scrolls to 1440 px on the page.
- Page URL: Fires when a visitor scrolls on a page with the chosen URL. For example, a visitor is on
https://clearbank.com/product-tour
and scrolls down to the chosen point. - Page path: Fires when a visitor scrolls on a page with the chosen page path. For example, a visitor is on
/product-tour
and and scrolls down to the chosen point. - Page hostname: Fires when a visitor scrolls on a page on a website with the chosen hostname. For example, a visitor scrolls down to the chosen point on all pages for
clearbank.com
. - Referrer: Fires when a visitor scrolls on any page to which they were referred by the chosen referrer. For example, a visitor comes from
https://clearbank.com/blog
to any page and scrolls down to the chosen point. - External referrer: Fires when a visitor scrolls on any page to which they were referred by the chosen external referrer. For example, a visitor comes from
https://medium
to any page on your website and scrolls down to the chosen point. - Campaign: Fires when a visitor scrolls on any page to which they were referred by the chosen campaign (based on a
utm_campaign
parameter). - Traffic source: Fires when a visitor scrolls on any page to which they came from the chosen traffic source: campaign, organic search, social, referral, direct.
- Returning visitor: Fires when a returning visitor scrolls down to the chosen point on any page (this mechanism is based on the Piwik PRO Tag Manager cookie).
- Variables: Any added variable will show up on the list of conditions and you can use it to define trigger conditions.
