A single-touch conversion means the user only engaged with one page before converting—but the definition varies:
Journeys — Single Touch definition: The user visited your site once, saw one page and then converted (e.g., Page A > Conversion, with no other pages in between).
Dashboards/Leaderboards — Single Touch definition: The user only ever saw one page (though they could have had multiple visits to that same page), but did not visit any other pages on their journey.
(e.g., Page A > Page A > Page A > Conversion)
Example:
Let’s take this journey: Page A > Page A > Page A > Conversion
In Journeys, this would be a multi-touch conversion. In Leaderboards, this would be a single-touch conversion.
Since these definitions are different, a single journey might be single-touch in Leaderboards, but multi-touch in Journeys.
