It takes up to 10,000 keywords, scrapes product data from 21 Amazon marketplaces, deduplicates listings by ASIN, and ranks products based on review-confidence rather than simple review scores. This process helps ensure that product recommendations are based on solid data, reducing the risk of promoting unreliable or unverified items.
