You can sync your Google Shopping Ads with your store by linking Shop App to the Google Merchant Center. 

Store Requirements

Before you upload your product feed to Google Merchant Center, you need to make sure that your store meets the Google Merchant Center requirements.

• Accurate contact information - You need to display sufficient contact information on your store website, including a physical address, a phone number, and/or an email address. 
• Refund Policy and Terms of Service - Ensure that you have a clear and conspicuous Refund policy and the Terms of Service on your store website. 
• Secure checkout process - Make sure that your website is SSL-protected and operates through a secure connection (https://).
• Language and currency - When submitting your product data to Google Merchant Center, you need to use the language and currency that's supported for your target country. Check the list of currencies and languages by country, if you are not sure what language and currency you are supposed to use.
• Shipping and tax settings - Your Google Merchant Center account must have the same shipping and tax (US only) settings as you have in your Shop App settings so that users understand the exact price they’ll have to pay, including the shipping and tax fees, from your Google Shopping Ads. You can find out how to set up shipping and taxes in your Google Merchant Center in these guides: Set up shipping, Set up taxes (the US only).

Product Feed Requirements

There is a number of attributes that should be included in your product feed so that your products can appear on Google Shopping ads. Make sure your products have all of these settings filled out, otherwise, your products will be rejected by Google Merchant Center.

Brand

The attribute is required for each product with a clearly associated brand or manufacturer. If the product is custom-made (e.g., custom t-shirts, art, handmade) or doesn’t have a clearly associated brand, the attribute is optional.

To add the Brand attribute to your product:

1. Go to your Products page.
2. Open the product you want to edit.
3. Switch to the Attributes tab.
4. Fill out the Brand field.
5. Click Save to apply the changes.

GTIN or UPC

GTIN (Global Trade Item Number) attribute is required for all products with a GTIN assigned by the manufacturer. This is the numerical value of the bar code.

To add a GTIN (UPC) attribute to your product:

1. Navigate to your Products page.
2. Open the product you want to edit.
3. Switch to the Attributes tab.
4. Fill out the UPC field.
5. Click Save to apply the changes.

Please note: some products don’t have a GTIN assigned, e.g. store brand products, replacement parts, custom-made products, art, and handmade items. For these products, you can submit Brand and MPN attributes.

MPN

MPN (Manufacturer Part Number) is required for all products that do not have an assigned GTIN. The MPN can be an alphanumeric string, so if your products do not have the manufacturer-assigned MPN, you can use your product SKU number for this attribute.

To add an MPN attribute to your product, first, you’ll need to create a custom product attribute:

1. Click on Settings in the left-hand sidebar, then select Product Types from the dropdown menu.
2. Type MPN in the text field for a custom attribute:

4. Fill out the MPN field.
5. Click Save to apply the changes.

Gender, color, age group

Attributes like gender, color, and age group are required for products submitted to the Apparel & Accessories category as they help customers filter by color, age, and gender on Google Shopping.

To assign these attributes to your products, first, you need to create an Apparel & Accessories product type:

1. Click on Settings on the left-hand sidebar and select Product Type from the dropdown menu.

2. Click Add New Product Type.

3. Expand the category tree or use the search box to find the product type suitable for your items:
