Shopping Insights pulls from the product data that you upload to Merchant Center. When a customer is shopping on your website and visits a product page where Shopping Insights is available, a Shopping Insights button will appear in the right of the Chrome address bar. The shopper will be able to click on the button and open the Shopping Insights panel.
If you'd like to opt out of this feature, please fill in this form, so Google can process this request. Once you have successfully opted out, the shopping insights button will stop appearing in the right of the Chrome address bar.
Note: The user requesting an opt-out must be an admin of the Merchant Center account and provide their Merchant Center account ID, or else this request cannot be processed.
