Rebuilding attribution to find the revenue last-click was missing
High-consideration trips sold across the US and Canada. A large share of bookings close offline or by phone with a travel agent, often days or weeks after the first ad click.
Last-click attribution credited only a fraction of the bookings paid media actually influenced. Budget was being set on numbers that understated the truth and hid where profit really came from.
Built a server-side tracking foundation (server-side GTM, Meta CAPI, Google enhanced conversions) to recover touchpoints the browser was losing, then added a multi-touch model and reconciled everything against confirmed revenue in the CRM: a three-lens view comparing platform-reported, multi-touch and CRM-confirmed outcomes.
On identical ad spend, the data-driven view surfaced far more bookings than last-click had credited, and a far higher true revenue ROAS, exposing channels that last-click was undervaluing and letting budget move to where it earned out.
