How to Find Your Amazon Cross-Sales and True Organic Sales

Accurate calculation of total ACOS and organic sales on Amazon requires distinguishing between same-ASIN and cross-ASIN (halo) sales. Amazon’s new reporting tool facilitates this by providing granular data that separates direct conversions from revenue generated by related products. Many sellers currently miscalculate profitability because they fail to account for cross-sales, where ad spend on one product drives revenue for a different SKU, effectively inflating the performance of the latter while penalizing the former. By integrating business reports with ad data through AI tools like Claude, sellers can isolate true organic performance by subtracting both same-ASIN and cross-ASIN ad-driven revenue. This analytical approach reveals the actual contribution of individual products, enabling more precise campaign optimization and a deeper understanding of how specific advertisements influence the broader product family's sales volume.
