How to integrate Google Shopping with an antiques store on Shopify?

I’m trying to set up my shop to work with Google shopping. There is a form for bulk editing that has a variety of tabs we need to input data. I am confused as to what we should we should enter, and where we will find that information. We are an antiques and vintage store, so we don’t have barcodes. Our Sku # s are made up for our personal inventory tracking.

QUESTIONS:

  1. Is there a form that shows examples of what should be in those boxes?

  2. Is there a listing we need to use with Google? If so, where do we get this list?

If you are using the free app, please be warned, it’s bugged. But the correct settings that you need to change is by going Shopify > Product > click on your product > more actions > Google > enable custom product.

Or in bulk go to Sales Channel > Google > Manage Availability > here set custom product to false

Again, most likely it will not work due to the app having bugs.

The better solution to accurately submit data is using a different app such as: https://apps.shopify.com/multiple-google-shopping-feeds
