To make sure that your setup works as expected, optimised prices will show in your Shopping ads on Google for only 10% of visitors for the first three days after automated discounts have been activated. After three days, 90% of visitors on Google will see optimised prices in your Shopping ads, and the remaining 10% of visitors won't view optimised prices because that traffic is used in tests to estimate your performance.
Depending on your product performance, it may take a few days or several weeks before measurements and reports of your performance begin to show in automated discounts. Learn more about how to view your product performance with automated discounts.
Note: Sale price suggestions will no longer be available in Merchant Center Analytics because the suggested prices will automatically be applied to the products that you've added to automated discounts. Learn more about pricing in Merchant Center Analytics.
