You can trigger a box based on the minimum time a visitor spent on the whole website by using the Time on Site assignment found on the Publishing assignments tab under Joomla User / Visitor. You can enter a time in seconds. For example: If you want to make a box available only after the visitor has spent 2 minutes on your whole website enter 120.
- Time is calculated based on the time visitor's session started.
- The calculations and the trigger take place on each page load.
- The calculated time resets when the browser is closed.
- If the time has come after the page has loaded then a new pageload is required.
If you want to trigger with a delay on every page load you should use the Animation > Delay option found on the Trigger tab.
