Keep a short question list
Start with three questions: what changed, where did it change, and what should we investigate next? Keep your review focused enough that you can repeat it each week. A small set of useful questions is easier to maintain than a report that tries to cover everything.
Use consistent comparisons
Save the property, filters, and comparison periods alongside your questions. Use complete periods when possible and note when recent data may still change. Consistent inputs make differences between reports easier to interpret.
Record decisions
For each finding, record the affected page or query, the evidence, and your next action. Assign an owner if you work with a team. If you decide to leave a page unchanged, record why; that context can be useful at the next review.
Close the loop
Begin the next review by revisiting earlier actions. Check what changed and whether the result supports your original hypothesis. Keep the questions that lead to useful decisions and revise those that repeatedly produce vague answers.
