Hi, I am wondering how to add the product-highlight attribute to my feed to the Google merchant center. I have been seeing a lot of products have these concise bullet points next to their product image in the shopping listing and I am wondering how can I add and edit the product_hightlight attribute to my data feed. Thanks.
Not many data feed solutions have this option. So I recommend you add a supplement feed using Google Sheets and add all the data.
