In a service-business enquiry flow, a shared campaign label mentioned more than one service. The follow-up logic chose from that label before checking the service the person had explicitly requested. The page and the follow-up message could disagree.
We changed the rule so the explicit request wins. The later handoff used the service already recorded in that conversation instead of guessing again from accumulated labels. Tests covered the exact conflict and a later change to the contact record. The release was verified without sending a test message to a customer.
A later change simplified the path to one acknowledgement and a clear human follow-up. These records prove the routing and handoff fixes. They do not establish a conversion lift.
From our article From paid click to customer: fix the whole handoff.
