A multi-campaign attribution methodology takes into measures the effect of a first touch (a campaign that first brought in an account), a last touch (a campaign that was presented immediately prior to the closing of a deal or creation of a sales-ready opportunity), and any significant re-touch events (campaigns that represent lead-nurturing and/or remarketing efforts).
