What Does the Price Mismatch Error Mean in GMC?
A price mismatch error in Google Merchant Center occurs when the product price in your product feed differs from the price on your landing page. Google checks if the price in your feed matches the price customers see on your website.
This error appears when Google finds different prices between these two sources. The system compares the base price, sale price, and currency. Google requires exact price matching to protect shoppers and maintain trust.
You must fix price mismatch errors within 28 days to keep your products active in Google Shopping ads.
