Recalculate historical attribution
Use historical recalculation when you change attribution rules or add mappings that should affect existing results.
Updated 7/17/2026
Recalculate historical attribution#
Historical recalculation reapplies your current attribution settings to past activity.
When to use it#
Use recalculation after:
- changing attribution model,
- changing attribution window,
- enabling or disabling direct or unknown replacement,
- adding important hostname mappings after traffic already arrived,
- importing older revenue.
What changes#
Campaign revenue, payer counts, and related campaign metrics may change. This is the point: Joinometry is re-reading past activity with your current rules.
What does not change#
Recalculation does not invent traffic or purchases. It only changes how existing player activity and revenue are connected to campaigns.
What to expect#
Large organizations may take a little time to finish. If a page looks unchanged immediately, refresh after a moment and check again.
