Document campaign conditions
Name, type, platform, duration, budget, discount and funding responsibility are not minor details. They are the basis for interpreting the outcome.
Separate ROAS from profit
Return on ad spend compares attributed revenue with advertising cost, but it may not deduct item cost, commission, packaging or discount. Profitability needs broader context.
Choose a suitable comparison
Use an appropriate period, branch or item reference and disclose attribution limits. A simultaneous increase does not prove that the campaign caused it.
