Maropost Merchandising Cloud is an ecommerce search, merchandising, and product recommendation platform designed to help online retailers improve product discovery and conversion. Its AI-powered search uses shopper behavior, natural language understanding, autocomplete, spelling tolerance, synonyms, and intent-aware ranking to return relevant products even when queries are vague or misspelled. Smart Collections automatically reorder category pages based on factors such as popularity, margin, inventory, and performance while allowing merchants to manually boost, bury, pin, or exclude products. The platform also delivers behavior-based recommendations such as recently viewed items, frequently purchased combinations, popular products, and personalized selections across home, product, cart, and category pages.
