Start with a decision
Ask what decision the report should help the team make: whether to adjust a campaign, improve a landing page, shift a budget or investigate lead quality. Choose metrics that inform that decision.
Reach, impressions and clicks describe activity. Leads, purchases and retention describe different outcomes. Neither group is sufficient on its own without context and a clear definition.
Define metrics consistently
Document how a conversion is counted, which source is authoritative, what attribution window is used and how duplicate or invalid events are handled. Keep definitions consistent between periods when comparing results.
Use tracking parameters and analytics events deliberately. Test them before a campaign starts, and record known gaps in consent, platform reporting or cross-device measurement.
Turn reporting into action
A useful report shows the metric, comparison period, context, limitations and the action being considered. Avoid presenting a change as caused by one campaign unless the measurement design supports that conclusion.
Record decisions and review what happened afterward. This creates a more useful learning loop than collecting dashboards without changing the work.
