Start with a decision: which channel should receive more budget, which page needs improvement, or which content is associated with enquiries. Defining the question first helps determine which data and metrics are needed.
Check how missing events, duplicate collection and internal traffic affect the results. Align dates, denominators, completion criteria and attribution models when comparing reports. Attribution assigns credit to touchpoints; it does not directly establish their causal effect.
A measurement plan can begin by defining required actions and completion criteria, then verifying collection. If you use GA4, identify the relevant events before marking business-critical actions as key events. Separating visits from successfully received enquiries lets you examine traffic growth and goal completion independently.
Repeat the cycle of collection, analysis, hypothesis, action and evaluation. Select methods such as A/B tests, funnel analysis or cohort analysis to suit the question. Intuition can help generate hypotheses; a single metric should prompt scrutiny of measurement and interpretation rather than a verdict that the team’s judgment was wrong.
