The Viewed Together algorithm recommends items by finding similar products that users visit. It generates recommendations based on the products visited in the same sessions and the same locale during the past 30 days. After generating recommendations, the Viewed Together algorithm orders the results based on their visit frequency (popularity). Thus, users can reach complementary or substitute products for the product that they are currently viewing. This increases discovery rates and the chance to grab users’ attention when they don’t have a target product. This type of algorithm works best on product pages.
