# How to use metafields to override values in Google Shopping Feed for Shopify?

## Metafield mapping in AdNabu's Google Feed App helps you map any metafield from Shopify to any other attribute in the Google Merchant Center.

Metafield mapping lets you map any metafield from Shopify to any other attribute in Google Merchant Center. By default, SKU in Shopify is used as MPN in the [Google merchant center](https://blog.adnabu.com/shopify/what-is-google-merchant-center-and-is-it-free/).

You can override this setting by [using Metafield](https://www.adnabu.com/features/customize-with-metafields) by following the below steps:
