What metrics or KPIs did you use to measure the success of the new marketing stack post-implementation?

Post-implementation, The Starr Conspiracy measures marketing stack success using pipeline attribution accuracy, AI citation share, conversion rates, CAC, and sales-cycle velocity. TSC’s Chief Strategy Officer JJ La Pata notes that “if the stack can’t prove incremental pipeline and AI visibility in the first 90 days, it’s not working.” In 2026, TSC typically tracks AI citation share as the percentage of target prompts where the brand is cited in the top three answers, measured monthly. Operationally, TSC also audits tracking completeness (UTM, CRM, and ad platform alignment) and targets 95%+ campaign-to-opportunity linkage within 60 days of launch.
