Overview
Your Okendo reviews can add star ratings and review counts to your Google Shopping listings and Product Listing Ads. Shoppers see that social proof before they click, which helps your products stand out in search results and capture more search traffic.
To show your reviews in Google Shopping, Google Merchant Center needs two feeds: your product feed (also called the Shopping ads or offer feed) and the Okendo reviews feed (the product ratings feed). Both feeds need matching product identifiers, such as GTINs and SKUs. If your reviews feed isn't syncing, check the areas below.
Before you begin
đ The Google Shopping integration is available on the Growth plan and above. View pricing.
Set up the integration first. See Google Shopping & Product Listing Ads.
Add product identifiers in Shopify
Give every product in Shopify both a SKU and a barcode (UPC or EAN). The more information Google has, the more likely your feeds sync. Google requires one of these for each product:
Product barcode/GTIN
Product MPN
â Google always prefers the barcode (GTIN). Add one to every product that has one.
The identifier types are:
Internal:
Stock Keeping Unit (SKU): usually eight alphanumeric digits.
Manufacturer Part Number (MPN): a series of numbers and letters.
External (Global Trade Item Numbers, or GTINs):
Universal Product Code (UPC): usually twelve numeric digits.
European Article Number (EAN): usually thirteen numeric digits.
International Standard Book Number (ISBN): specific to books, thirteen numeric digits.
Enter these on each product's page in Shopify. For variants, click Edit next to the variant.
Use SKUs as MPNs
Shopify has no MPN field. To fill the gap, Okendo can send each product's SKU as its MPN. Turn this on in Okendo Admin > Settings > Integrations > Sales & Marketing > Google Shopping. This helps Google match your products, but doesn't guarantee a match.
Check your Google Shopping Feed app settings
If you use the Google Shopping Feed app to pull your product feed into Merchant Center, check both the default and the product-level settings:
Integrations > Feed Settings > Default Settings > Default Identification Management: select Submit Brand Name, MPN (SKU), and GTIN (Barcode).
Manage Products > Product XYZ > Identifier Management: select Submit Brand Name, MPN (SKU), and GTIN (Barcode).
Check SKUs in Google Merchant Center
Okendo builds the reviews feed from your Shopify inventory, using the SKU for MPN and the barcode for GTIN. Make sure the SKUs and GTINs in your Merchant Center product feed match the ones in Shopify.
Where to find the SKU in Google Merchant Center:
Common error messages and solutions
Missing value [gtin]: the product doesn't have a GTIN.
Invalid value [gtin]: the product's GTIN in Shopify isn't in a valid format, for example it's missing digits.
Violation of Shopping ads policy: Google has flagged your product for a policy issue. Click the product to read the violation details.
Ambiguous value [gtin]: Google doesn't recognize the GTIN, for example because leading zeros are missing or it uses an old format such as ISBN-10.
Unsupported value (reserved) [gtin]: GS1 hasn't released the GTIN for use yet.
FAQs & Troubleshooting
Q: Why don't my Google Shopping review counts match Okendo?
A: Usually the SKU or GTIN in your Merchant Center product feed doesn't match your Shopify inventory, so Google can't match some reviews to products. Update the product feed with the same identifiers you use in Shopify. See Check SKUs in Google Merchant Center above.
Q: Does Okendo create or change my product feed?
A: No. You create the product feed in Google Merchant Center or with a third-party app such as DataFeedWatch. Okendo only provides the reviews feed, and doesn't create, control or modify your product feed.
