How to Resolve Limited Performance Issue in Google Merchant Center

As a Shopify store owner, you may encounter the issue of limited performance in your Google Merchant Center account. This issue arises when there are missing identifiers for your products, specifically the GTIN, MPN, and brand information. While these identifiers are essential for products sourced from other retailers, as a store owner manufacturing and selling your own products, you may not have these unique numbers. Fortunately, there is a solution to this problem.

To resolve the limited performance issue, you need to update the "Identifier Exists" attribute in your Google Merchant Center account. This attribute tells Google that your products do not have a unique identifier and that they should pull the necessary information directly from your Shopify store. Here's a step-by-step guide on how to make the necessary updates:

  1. Access your Google Merchant Center account and navigate to the "Products" section.
  2. Click on "Feeds" and select the primary feed associated with your Shopify store.
  3. If you have set up an automated feed using Google Content API for Shopping, your product information will be automatically fed to the Merchant Center. If not, you will need to manually update your product feed whenever there are changes.
  4. Click on the feed name to access its settings and then select "Feed Rules" next to the settings option.
  5. Click the plus button to create a new feed rule, and search for the attribute name "Identifier Exists."
  6. Select the "Identifier Exists" attribute and proceed to change its value from true to false.
  7. Remember to save the changes as a draft before applying them to your feed.
  8. You can test the changes before applying them to see how they will impact your products.
  9. Once you are satisfied, apply the rules, and your Google Merchant Center account will be updated accordingly.

By setting the "Identifier Exists" attribute to false, you inform Google that your products do not require GTIN or MPN numbers. This ensures that your products can still be listed on Google Shopping without encountering the limited performance issue.

Updating the "Identifier Exists" attribute is a one-time setup that saves you from the hassle of manually managing these identifiers for each product. Any future updates or changes to your products in the Shopify store will be automatically synced with the Google Merchant Center, keeping your product feed up to date.

Automating your product feeds using Google Content API for Shopping is highly recommended to streamline the process and ensure seamless updates. This eliminates the need for manual updates and reduces the chances of missing identifiers.

Setting up your Google channel on your Shopify store and understanding various marketing tactics can further enhance your online store's performance. Explore additional resources and playlists to learn more about leveraging Google Shopping and ranking on Google search for increased sales.

In conclusion, resolving the limited performance issue in your Google Merchant Center account is crucial for Shopify store owners selling their own products. By updating the "Identifier Exists" attribute and automating your product feeds, you can ensure your products are listed on Google Shopping without the need for unique identifiers. Keep your Google Merchant Center account synchronized with your Shopify store for a seamless selling experience.
