Click tracking allow tracking solutions such as Impact to track when the user clicks on something. In truth, clicks can either be tracked directly on the website (the user ends up clicking through into a landing page anyway) or can be trafficked in the advertiser’s ad management system as a 3rd party click through callout. In a web environment, the click tracker is often an executable tag, though pixels are also viable. In-app requires a dedicated API for click tracking since Javascript tags cannot be used within an In-app environment. All necessary contextual information about the referrer (the original publisher or media partner source of the click) is passed along with the click tracker
