Google announced that it has connected location targeting in AdWords to Google Maps to provide more info about locations, make relevant location suggestions and improve accuracy in targeting.
The improvements include an easier way to discover locations, a new "reach number" column to show the number of users seen on Google properties, increased the location target limits from 300 to 10,000, and a new Polygon targeting migration tool.
Google says it will use the “limited reach” label to indicate locations where it isn’t able to associate users with a selected location based on IP. Google says it will primarily use user intent data for targeting in these instances.
When an advertiser targets a radius, it’ll show “locations within this target”.
Finally, Google is getting rid of polygon targeting. It will be supported only through the end of the year. Google recommends using the “Target a Radius” feature instead.
