  • Direct upload
  • FTP & SFTP upload

  • Scheduled fetches (GMC downloads your data from your feed URL, and uploads to its platform)

Google Merchant Center is not accepting every type of file for feeds. The feeds should be in Tab-delimited (.txt), comma-separated values (.csv), tab-separated values (.tsv), RSS 2.0 XML or Atom 1.0 XML. Unfortunately, (.xls) files are not accepted by Google. You can also upload compressed version of your file - compressed file types should be in Gnu zip (.gz), Zip (.zip) or Bzip2 (.bz2)

Google Merchant Center is allowing the size of files under 4 GB. It is valid for scheduled updates, SFTP, and FTP files, too. If you are using compressed files, it should not be over 500 Mb.

  • Mandatory attributes are id, title, description, link, image_link, price, condition, availability, brand, and gtin. You can use mpn, or identifier_exists fields, if your products don’t have gtin.
  • If you are an apparel retailer, age_group, gender, color, size, and material fields are also very important. You need to consider adding them for each of your item.
  • For shipping cost, it is required to add details if you did not define in Google Merchant Center and if you are from these countries Australia, Austria, Belgium, Canada, Czechia, France, Germany, Ireland, Israel, Italy, the Netherlands, Poland, South Korea, Spain, Switzerland, the UK, and the US
  • It is also important to check local laws and regulations because if it is required for your country, you should also add these attributes as a mandatory field: tax information, shipping cost, the minimum unit pricing measure, unit pricing base measure, energy efficiency class, the minimum energy efficiency class, the maximum energy efficiency class

3- Language of your items

The language of the product should match between your feed and your website. If you want to use different languages, make sure that you are uploading different product data and linking the products in the languages that you are using.

After using Google Merchant Center

You should update your data at least every 30 days to save your account’s active status. Losing your active status might prevent using google merchant center and disables your ads. However, for an average retailer 30 days is very long for updating product information. On average, retailers update their information 6 times a day. Additionally, your price and availability fields may change more quickly than expected. This might cause some  errors in GMC platform.
