Every marketer worth their salt is concerned about incrementality. Companies have, and should be, reevaluating their budgets, channels and service providers based on the ability to drive sales from advertising that they wouldn’t have captured otherwise.

When it comes to Amazon, this issue is particularly important, because current SERPs can naturally cannibalize an otherwise organic sale with an ad for the same product that shows up prior to the organic result. For marketers, the key to managing this issue and driving incremental sales is through a combination of segmented bidding strategies for brand, category, and competitor key terms, contextualizing Advertising Cost of Sale metrics, and proper campaign structure.
