## Merchant Center

A Merchant Center account lets you use Merchant Center, which is a free
tool that helps millions of shoppers on Google discover, explore, and buy your
products. With a Merchant Center account, you can upload and manage your
product data so that your products appear across Google Search, Maps, YouTube
and more.

If you already have a Merchant Center account, you can use it.
