Tracking Link Parameters

Singular supports a variety of parameters added to Singular tracking links. When populated by the ad network that serves the tracking link, these parameters provide Singular with a wealth of information about the click or impression, which Singular uses to enrich reporting data.

Some tracking link parameters are also used to augment how links behave or what attribution methods are supported.
