Step 3. Set up placement region and language

Google Merchant Center will display product ads according to your placement region and language.

Choose the placement region and language. Then, click Add new languages to the list below.


  • If you set Taiwan as the only placement region, your ads, and YouTube Shopping products will be visible exclusively to customers in Taiwan through livestreams, videos, and Shorts. To reach customers outside Taiwan, add another placement region. Ensure that your store logistics options support the selected region.
  • If you select "Traditional Chinese" as the "Placement Language" please ensure that the "Name", "Summary", and "Description" fields for all products in the store contain corresponding content in Traditional Chinese. If not, the products will not be uploaded.
