What Remarketing audiences cannot be defined by default?

Google Analytics collects data on user behavior on websites and apps. It can track language settings, video interactions, and page visits, making these suitable for remarketing audiences. However, Google Analytics, by default, cannot track visits to a physical store. This type of data typically requires integration with other systems, like point-of-sale data or beacon technology, which are outside the scope of standard Google Analytics tracking. While Google does offer solutions like Store Visits conversions in Google Ads, this is not a remarketing audience definable within Google Analytics itself without additional, non-default integrations.
