This location setting is interesting for local businesses looking for new offline visitors. In Instaon, we cover this goal with “Location visitors”.
The idea is to put your business address with a given radius (ex. 4miles/km). As a result, only users within a reasonable distance from your shop will be able to see your ads. (and then walk or ride to your shop to buy your product/ service )
You will see the covered area and estimated reach after your selection. Keep in mind to have enough estimated volume. Putting less than 3miles/km as setting, will often lead to few clicks and poor performances (unless your business is located on Time Square)
