Analytics refers to data that is analyzed to inform business decisions or technical processes. In ecommerce, tracking click and conversion events can provide valuable insights for improving business operations holistically. AI-powered tools like Algolia Recommend use analytics to train models on product catalogs and make recommendations based on user behavior. By starting to track as much data as possible from day one, developers can avoid the problem of duplicated or inconsistent data across multiple analytics systems, ensuring a more accurate understanding of customer flows and business performance.
