Data Feed Definition
A data feed is a structured file or stream, typically in CSV, XML, or JSON format, that automatically transfers data from one system to another on a regular basis. In e-commerce, the most common example is the product feed: a file containing titles, prices, images, availability, and other attributes that a shop sends to sales channels such as Google Shopping, Amazon, or a marketplace.
How does a data feed work?
A source system, often a PIM or ERP, exports a defined set of fields in the format a destination requires. The feed is then delivered on a schedule or triggered by an event, so a price change or stock update can propagate to all connected systems automatically. Because every channel has its own required attributes, accepted values, and category taxonomy, feeds usually involve data mapping and transformation before export.
Why does feed quality matter?
On shopping channels, the feed largely determines visibility: platforms match search queries against feed content, not keyword lists. Thin, incomplete, or incorrectly formatted feeds lead to rejected listings, poor placement, and inconsistent product information across channels. Enforcing schema validation and a clear data specification for incoming feeds resolves most of these issues before they reach any downstream system.
What is feed management software?
Dedicated tools such as Channable or Productsup sit between a data source and hundreds of channels, handling per-channel formatting and rules. They work best when fed clean, complete source data, which is why they are commonly paired with a PIM or MDM system acting as the single source of truth.
