使用哪一項位置資料來源時，你必須設定帳戶並連結至 Google Ads？

To leverage location data for offline sales in Google Ads, you must link your Google Business Profile (formerly Google My Business) account. This is because Google Business Profile is the primary platform where businesses manage their local listings, including addresses, hours, and other essential information that Google Ads uses for location extensions and store visit tracking. While Google Ads is the advertising platform itself, it pulls location data from Business Profile. Google-indexed chain stores refers to how Google might categorize businesses, not a data source you directly configure. Google Merchant Center is for product listings and shopping ads, not for general business location data.
