Google Shopping's product ratings are the best way for products to appear. This is a popular way for shoppers to locate products online. You can give searchers a rating to help them decide if your products are worth their time.
Google Shopping listings' star rating system makes it easy to compare multiple options and can increase the chances that you have a high rate of click-throughs from Google Shopping Ads. It is important to remember that ratings will only be visible in your Google Shopping listing if you meet all requirements.
Submit a review feed in Google Merchant Center to get Product Ratings displayed on your listings. An XML file containing information about your products as well as reviews is the reviews feed. The feed needs to be updated monthly to remain eligible, so be sure to check it on a regular basis!
You should also ensure that all of your reviews meet the following quality guidelines:

A quality review should share in-depth research and real subject-matter expertise. This will help your reviews stand out from the crowd and attract more customers.
This is an excellent place to begin because it's easy and free to build a strong reputation online for your company. This can also be used to get testimonials from loyal customers.
You will need to register with Google in order to get started. This can take a few weeks, so be prepared to wait.
Once you have your Google Shopping account created, you can start a campaign in Google Shopping that will drive traffic to your shop and convert sales. The ad should contain the average star rating of your products as well as your reviews.
These ratings can be displayed in Product Listing Ads (PLA), and catalog. This can help increase conversions from Google shoppers looking for a particular product. This feature is available in all countries where Google Shopping has been launched.

Good reviews are essential for eCommerce businesses. The Google product reviews program can help increase sales and customer satisfaction. The program is easy to set up and requires a minimum of 50 reviews across all of your products.
Yotpo will automatically feed your reviews and display them on your product details page. You can also upload user-generated photos you have taken on your website.
How the Product Review Programme Works
Google's product reviews program is free and allows retailers to gather feedback from customers about their products. The program sends out emails to customers around the day they expect their purchase, and it asks them to rate the product they've purchased from your company.
After you have submitted a review the feedback will go back to you via email. You can also view it in Google Merchant Center. You can also use your feedback to refine your products.
