Product data & data quality
Product data & data quality: clear information for sellers and buyers
Product data determines whether an item is found and bought correctly. This article explains required fields, variant handling, measurements and technical specs, categories and data maintenance in practical steps.
Essential product data: what should always be present
Good product data starts with clear mandatory fields. These include a distinct title, a concise description, brand or manufacturer, an article number (SKU/GTIN when available), and physical dimensions and weight. Many products require additional mandatory details: energy labels for appliances, material composition for textiles, or safety information for children’s items. These details help customers compare products and meet legal or platform requirements. Images with sufficient resolution and consistent views are equally important. Missing basic data reduces discoverability in search filters and leads to more questions and returns.
- Title, brand, SKU/GTIN
- Clear product description
- Dimensions, weight, material
- Relevant legal mandatory information
Manage variants correctly: Variants are a standard part of product data management. A variant is the same product family in a different size, colour or specification. It is important to group variants under a parent product instead of creating separate product entries. This avoids duplicates and improves the shopping experience. Each variant needs its own attributes, such as colour, size or storage capacity, as well as unique identifiers and stock levels. Clear naming rules help customers spot differences quickly. If prices, shipping or lead times differ between variants, show that information transparently.
- Parent product with variants
- Unique identifiers per variant
- Transparent differences in price/availability
- Consistent naming (e.g. colour/size)
Structure technical specs and measurements: Technical specifications and measurements often decide purchases. Instead of long paragraphs, use structured fields: length, width, height, weight, power ratings, connector types or compatibility lists. Use consistent units (e.g. cm, mm, kg) and note tolerances or measurement methods when relevant. Tables or lists improve clarity for technical items; size charts and fit notes help for clothing and furniture. Structured fields improve filterability in the shop and simplify integration with marketplaces or comparison services.
- Structure instead of free text for technical specs
- Consistent measurement units
- Tables or lists for comparability
- Make compatibility and connection details clear
Categories, maintenance and quality control: Categorisation and ongoing data maintenance are crucial over time. Place products consistently into suitable categories and use a taxonomy that external platforms can interpret. Define who is responsible for updates: who adds specs, who renews images, who checks mandatory fields? Automated validation rules (required fields, correct units, image formats) help prevent errors. Regular spot checks and a change log show how current the data is. Good processes reduce returns, lower customer queries and ease integrations with marketplaces or ERP systems.
- Consistent categorisation
- Defined responsibilities for data maintenance
- Automated validation rules
- Regular spot checks and a change log
