Ktorý zdroj údajov o polohe vyžaduje nastavenie účtu a jeho prepojenie so službou Google Ads?

The correct answer is Firemný profil (Business Profile). To display accurate location information in Google Ads, such as location extensions, call extensions with location details, or local inventory ads, you must link your Google Business Profile account to your Google Ads account. This allows Google Ads to pull verified business address and store information directly from your Business Profile. Googlom vybrané reťazce (Google-selected chains) is incorrect because while Google may identify chains, you still need to manage your specific business locations through a Business Profile. Google Merchant Center is used for product feeds for shopping ads, not for managing physical business locations for general ad extensions. Google Ads itself is the advertising platform, not a source of location data that requires linking to itself in this context; it uses the linked Business Profile data.
