 How to specify locations
■Specify location name
Select locations at the location levels as below, and set it for the ad group. Multiple locations can be selected.
	
Prefecture
	
City, ward, county
Note
	
With default settings, no location is selected. Your ads will be delivered to all internet users without no relation to location.
	
The accuracy of targeting is not guaranteed by Yahoo! Japan. Selected settings and other factors may cause inaccuracies with this targeting.
■Specify radius
There are two ways to set up radius targeting. You can use both geo (locations) targeting and radius targeting.
	
Specify using a pin
	
Enter a spot name, address, zip code, or latitude and longitude. Then specify a location based on the suggestions.
Note
	
If the location and radius overlap in the same ad groups, ad delivery and reports for that area will differ based on your bid adjustment rate.
The details are as follows.
-Ads will run when the bid adjustment rates for the location and radius targetings are the same. Radius targeting will have priority on the reports.
-Ads that have higher bid adjustment rates will run and show on the reports when they have different rates.
	
Your ads won't appear in unavailable locations, such as outside Japan, regardless of your settings.
	
Your ads won't run regardless of your settings if you specify an area that has a small audience (An ad group determines the number of an audience). To check the result, see the performance report.
	
Target more locations if your ads aren't running:
-Specify wider locations
-Make the same ad groups have the radius targeting
	
Don't narrow down your audience too much. You may lose ad delivery chances.
