Read conversion lag before judging results
Give recent clicks time to produce their expected outcomes.
The scenario
A business sees half of qualified leads within two days and most of the rest within two weeks.
Yesterday's spend divided by yesterday's closed outcomes mixes fresh and old cohorts. Recent CPA is incomplete until the lag has matured.
Apply it to your own work
Build a table of conversion age by click or lead date. Report mature cohorts separately and label current-period forecasts.
What to watch for
A longer attribution window does not create more actual sales. It changes which outcomes are observed and credited.
Estimate what is still pending
Use older cohorts to estimate how many qualified leads typically appear by age. If 70% of eventual leads are usually visible after a week, seven observed leads could suggest around ten at maturity under the same mix.
Report the seven observed leads as facts and the ten as a forecast. If a new channel has a different close cycle, use its own maturity curve. Revisit the estimate when the cohort reaches the agreed review date.
