A vendor-published case study reports a large reduction in cost per lead after enabling compliant conversion data sharing to ad platforms. The case study attributes the improvement to replacing or remediating tracking that previously broke conversion signals.
Critical evaluation:
- This result is reported by the vendor; methodology details (time window, channel mix, attribution model, seasonality, creative changes, landing page updates) are not fully disclosed in the vendor excerpt.
- The magnitude of reported improvement is plausible where conversion signals were previously unavailable, but buyers should request additional details such as baseline period definitions, whether CPL is measured using platform-reported conversions or confirmed leads, whether lead quality changed, and whether vendor fees were included in ROI calculations.
