Product feed
A product feed is a structured file (usually CSV, TSV, or XML) that lists every product you sell along with the attributes each sales channel needs, like title, price, image, and availability.
Think of a product feed as your catalog translated into a language that ad platforms and marketplaces can read automatically. Instead of someone at Google or Meta browsing your site, their systems pull your feed on a schedule and use the fields inside it to build product ads, shopping results, and catalog listings.
Each row is one product (or one variant), and each column is an attribute. Some attributes are required, some are recommended, and some are optional but improve performance. Get the required ones wrong and the product gets rejected; get the recommended ones right and the same product tends to show more often and for better searches.
The feed matters because it is the single source of truth the channels act on. If your price is stale in the feed, shoppers see the wrong price. If a product is out of stock on your site but still 'in stock' in the feed, you pay for clicks that cannot convert. Accuracy and freshness are the whole game.
In MartechFlow, a product feed is what you ingest, transform, and export. You connect a source (a live URL, a Google Sheet, or an upload), map your raw fields to the attributes each channel expects, apply rules, and publish a clean, channel-ready feed at a stable URL the channel pulls from.
