I would suggest looking into an app such as Google Customer Reviews. With this app you can show Survey Opt-in to your customers who place an order at your store. The app will send the survey feedback requests a few days after the expected delivery date of the order. The reason I think this is a great option for you is with these types of reviews it will display these seller ratings on your Google Search and Shopping Campaigns as well. These are the star ratings you will sometimes see integrated into a search listing on Google when you search for something such as "Red Tennis Shoes":
The app is a one-time $25 fee and is then yours to use. If there is anything else I can help you with, please let me know.
