Refers to the fractional conversions allocated by an attribution model to the channels, campaigns, keywords, placements or whatever attributable element. For instance, for a conversion path consisting of a paid search touchpoint followed by a display touchpoint leading to a single conversion, and assuming an even distribution of credit (i.e. a linear attribution model), the paid search channel gets an attributed conversion of 0.5 and the display channel gets an attributed conversion of 0.5
