Algolia AI Recommendations can be added to a Shopify store to provide personalized navigation and recommendations, enhancing user experience and driving revenue. Unlike the free Shopify Search & Discovery app that offers limited recommendation models, Algolia leverages features such as "frequently bought together," "similar items," and "trending products" for more sophisticated and accurate suggestions. It can also pull data from various sources to create a unified experience for customers. Sharing event data with Algolia helps improve engagement and conversion rates by training recommendation models based on customer behavior and preferences.
