When interpreting scanner data for promotional effectiveness, accounting for seasonal variations is crucial. Seasonal variations can significantly impact consumer buying behavior and sales patterns. For instance, certain products may experience fluctuations in sales during holidays or specific seasons, such as increased sales of ice cream in summer or holiday decorations in December. By considering these variations, analysts can differentiate between the effects of promotions and natural seasonal patterns in sales, leading to a more accurate assessment of promotional success.

The other options do not provide a comprehensive understanding of promotional effectiveness. Focusing only on total sales neglects the context in which those sales occur, including influential factors like timing and market conditions. Relying solely on historical data can limit insights since it may not capture the evolving nature of consumer behavior and market trends. Lastly, eliminating competitive influences may oversimplify the analysis, as competitors' actions can also significantly affect performance metrics, making it essential to consider all factors that could impact sales during a promotional period.
