To enable machine learning, personalization, or even simply search and filtering, product tagging in ecommerce entails descriptive tags assigned to products to help to organize, document and track their progress. In essence, product tags are keywords, attributes, or qualities used for product identification within the website, which can range from the very broad to the ultra specific. For example, a fashion product can be tagged with a price category, brand, material, color, style, or psychographic property. In this way, product tags sort products by a certain feature and allow a specific, narrow product search so that products can be easily found by consumers. In ecommerce, product tagging must be consistent, updated, and accurate to enable relevant product search and discovery and a great customer experience.
