Introduction

Google Shopping Ads with product ratings can significantly boost your product visibility and trust among potential customers. However, to ensure accurate matching and attribution of ratings to your products, supplying strong ID data is crucial. This comprehensive guide explains how Google matches products, the importance of GTINs (Global Trade Item Numbers), and various methods to supply strong ID data to Feefo.

How do Google match products?

Google matches your review data to products based on various factors, with Global Trade Item Numbers (GTINs) being the strongest identifier. If GTIN data is unavailable, Google will attempt matching using other metadata, such as SKU, Brand + Manufacturer Part Number (MPN) pairs, or Product URLs. However, GTINs are preferred as they offer the best match accuracy.

How can I supply strong ID data to Feefo?

To ensure accurate matching of your product ratings, you can supply strong ID data to Feefo through various methods:

Recommended option

Set up a connection between your Feefo and Google Merchant Centre accounts.

Alternative options

1. Provide the product GTIN along with each transaction in your sales data:
   • If you send data via a sales file
   • If you send data via our Entersaleremotely API
2. Upload a manual product catalogue to your Feefo account, providing a list of your product SKUs and their corresponding GTINs

If your Feefo account spans multiple language domains we recommend supplying the GTIN data via your transactional feed, alternatively please contact Feefo Support for further guidance.

All of the above methods also support a Manufacturer Part Number (MPN) if your products do not have a GTIN.

Google emphasise that this option does not guarantee as reliable a match

Adding the product GTIN etc to the sales data is the only way that multi language customers can provide this if it is all from one website URL, so that they can ensure the right product description and URL match to the right language.

It is a standard, which means it represents an agreed industry-wide format for expressing something, in this case the number that identifies an item. 

Please be aware that a GTIN is allocated centrally by the organisation GS1, cannot be arbitrarily assigned and are strictly numeric.

The inclusion of gtin or mpn and brand in your sales data or product catalogues will be required in future releases. Maximum character length is 14 characters (see below for the different formats). Mainly used by retail merchants selling branded products to ensure accurate matching of Feefo reviews to products when submitting to Google’s product rating programme.  gtin is not used for unbranded products or for those that do not have a GTIN; use mpn and brand instead.
