What is a product feed?
A product feed is a structured file (usually CSV or XML) that lists your products and their attributes: id, title, description, price, availability, image, and identifiers like GTIN. Channels such as Google Shopping, Meta, TikTok, and Snapchat pull this file from a URL on a schedule and use it to build Shopping ads, catalog ads, and storefronts.
The catch is that every channel has its own spec. The same product needs slightly different fields and formatting for each one. Product feed management is how you produce all of those correct, up-to-date feeds from one source of truth.
The four jobs of feed management
Every feed tool, MartechFlow included, exists to do four things reliably and at scale:
- Ingest: pull your catalog from a URL, file upload, Google Sheet, or store connector, even when it runs to millions of rows.
- Transform: map, rename, combine, and compute fields with rules so the data matches each channel’s spec.
- Validate: check every product against the channel’s required fields and surface what would be disapproved before you publish.
- Publish: export a channel-valid file to a stable URL and refresh it on a schedule without ever shipping a broken feed.
Why feeds get disapproved
Most disapprovals come from a handful of recurring issues: a missing required attribute (often GTIN or brand), a title that is too short or keyword-stuffed, a price that does not match the landing page, an availability value in the wrong vocabulary, or an image that violates policy.
The fix is rarely product-by-product. It is usually one rule applied across the catalog: derive brand from a column, enforce a title template, map availability to the channel’s wording. A good feed tool turns disapprovals into a short, ranked fix list instead of a wall of errors.
One source, many channels
The scalable pattern is to ingest your catalog once into a single normalized state, then generate per-channel output feeds from it. A campaign-URL change or a new channel should not require re-ingesting a million rows. MartechFlow separates capture (ingest) from output shaping (export) so output edits are cheap and channel formatting is automatic.
Where image creative fits
Feeds move data, but shoppers respond to images. Rendering sale badges, frames, and dynamic text onto product images from live feed data, server-side and across the whole catalog, turns a price drop in the feed into visible creative in the ad. MartechFlow builds this into the same pipeline so you do not need a separate design step.
