When you create an advertisement with Shirofune, a product called "brand name" is registered by default in addition to the products registered from the screen, but the purpose is to use designated keywords such as site name, company name, service name, etc. It is a product for registering and managing.
As with other products, it is possible to edit keywords in detail and set the ad text / area (= when the detailed setting function is turned on for the ad text and area).
However, since the advanced function is turned off by the default setting of the brand name, the area is set to be distributed nationwide, and the ad text is set by automatically copying the ad text other than the brand name.
If you want to set the area / ad text individually for the brand name, click "Detailed settings" on the ad creation> ad confirmation screen, and the detailed function will be turned on and you can set it.
