Google Merchant Center is a free platform that helps you upload your product information to Google and make it available to shoppers across the web. You can use Merchant Center to improve your visibility on Google Shopping and other Google properties. While there is no charge to use Merchant Center, you will need to pay for clicks on your Google Shopping ads. These charges vary depending on the amount you bid and your overall ad quality. However, you can control your costs by setting a maximum bid and carefully monitoring your ad performance. By using Merchant Center, you can reach new shoppers and grow your online business.
