Brand presence	`brands`, `brand`, `organicProducts`, `sponsoredProducts`, `combinedProducts`	Brands and their organic, sponsored, and combined product counts in the observed results.
Share of voice	`organicBasicSov`, `organicWeightedSov`, `sponsoredBasicSov`, `sponsoredWeightedSov`, `combinedWeightedSov`	Reported basic and weighted shares, from 0 to 1, for the indicated placement types.
Position and price	`organicAveragePosition`, `sponsoredAveragePosition`, `organicAveragePrice`, `sponsoredAveragePrice`	Average observed ranking positions and product prices by placement type.
Top ASIN response	`topAsins`, `asin`, `clicks`, `conversions`, `conversionRate`	Identifies top products and reports their modeled-window clicks, conversions, and conversion rate.
