Why this happens

Technical root cause

Feeds frequently export the thumbnail rendition instead of the master asset, because the thumbnail is the URL the storefront exposes first in its product payload.

Google Merchant Center reports it as Image too small [image_link] and applies: Product disapproval — offers without a valid image cannot serve.

Native CMS friction

  • Shopify

    Image URLs carry a size suffix such as _small or _grande; exports that reuse the storefront rendition inherit the smaller size.

  • VTEX

    Image URLs embed the requested dimensions in the path, so whichever rendition the API returns becomes the feed image.

  • WooCommerce

    The default export can pick the registered thumbnail size rather than the original upload.

Fixing it manually

  1. 1

    Open a rejected image URL and check its real pixel dimensions.

  2. 2

    Locate the original upload URL without any size suffix or resize parameter.

  3. 3

    Replace the feed image URL with the full-size asset, keeping HTTPS and a stable path.

  4. 4

    Re-upload products whose master image is genuinely below the minimum with a new photograph.

  5. 5

    Request a re-crawl and confirm the image passes.

The IRONFEED automated solution

One rule, applied to every product on every export. No spreadsheets, no re-uploads.

Rule syntax
IF image_link CONTAINS size_suffix OR width < 800
  SET image_link = strip_size_params(image_link)
  ELSE SET image_link = first(additional_image_link) WHERE width >= 800

Run automatic linter checks before Google Merchant Center crawls your feed. IRONFEED validates every export against the channel spec, so this error is caught in Feed Review instead of in your channel dashboard.

Invalid URL in link or mobile_link

Tracking parameters are appended by string concatenation, which produces double question marks, unencoded spaces or duplicate UTM keys. Some exports also emit a path without the domain.
