b2b marketing attribution after a commerce replatform
we replatformed our commerce backend last year and our marketing attribution has been off ever since, with our MTA numbers contradicting both salesforce and our own holdout tests, and the CRO doesn't trust any of it anymore.
we've been throwing fixes at it. Stood up a fresh attribution model from scratch, ran a 10% holdout on our nurture programs, cross-referenced campaign UTMs against opportunity creation in salesforce, and rebuilt the marketing data warehouse table by table.
some of it helped, but marketing and revenue leadership still aren't on the same page.
so for any b2b marketers who've been through a commerce replatform, how long did it take you to get attribution back to a place leadership trusted?
and beyond the technical fixes, what CRO conversations or rituals helped restore the trust?
