Onboarding Guide

Upload a feed

After you've created and registered your feed, use it to upload your data.

Before you begin

To minimize delays, ensure that your product data conforms to the products feed specifications and the feature. policies, including Shopping ads policies and policies for listing your products for free on Google.

If you're not sure about the status of your products after an upload, review your product status definitions.

  • A full feed should be submitted at least every 30 days. If your product data changes regularly, you may upload your full feed up to 4 times per day.
  • If you submit multiple feeds, keep each item in the same feed with each submission. Avoid moving your items to different feeds.
  • If you submit your products for the first time to a particular target country, it may take up to 3 business days for your products to be reviewed. If you submit a feed for a beta target country, it may take significantly longer for your products to be reviewed. Learn more about beta target countries
