Rockerbox first-click vs last-click is not Northbeam first vs last
Stack first-click $ beside last-click $. Take |first-click − last-click| ÷ last-click. That is credit-gap %.
Pair: First-vs-last-touch gap on Traffic. Northbeam twin: first-vs-last-touch. Mix twin: MMM vs MTA.
What you type
First-touch $ — Rockerbox revenue credited to the first click in the named span.
Last-touch $ — Rockerbox revenue credited to the last click in that same span.
Credit-gap % = |first-click − last-click| ÷ last-click × 100. When credit-gap % runs hot, revisit path length and assist rules on Rockerbox — never invent a credit-gap chip.
What not to do
Skip inventing credit-gap %. Skip dropping Northbeam dollars into Rockerbox fields. Skip treating MMM vs MTA as first-click vs last-click. Skip merging spans when one campaign owns the skew.
