ECommerceKatalogen

ECommerceKatalogen is an online catalog platform and price comparison service that aggregates product data from participating retailers to present a searchable catalog of consumer goods. The service aims to standardize product information across retailers, enabling users to compare prices, availability, and product specifications from a single interface.

The project originated in the Nordic e-commerce scene as a collaborative effort among retailers and consumer-advocacy groups to improve transparency and streamline catalog publishing. Since its early adoption, it has expanded to multiple European markets and supports several languages and currencies.

Data and operation: ECommerceKatalogen collects product data through retailer feeds, partner APIs, and, where permitted, automated crawls. Each product entry includes fields such as identifier, name, brand, category, price, currency, availability, retailer, URL, and images. The platform uses a standardized data schema to enable cross-retailer comparison and updates records regularly to reflect price and stock changes, while offering an API and a web widget for retailers to display catalog content.

Governance and reception: The platform generates revenue through affiliate links, sponsored listings, and enterprise subscriptions. It emphasizes data quality, privacy, and compliance with retailer agreements. Critics note dependence on retailer-provided data can affect accuracy and timeliness, while supporters cite greater price transparency for consumers.
