In order to make their advertising campaigns more fruitful, merchants can use various methods for finding potential customers that fit their profile. This includes a number of factors, including the age of the potential customer, gender, hobbies, etc. On top of that, in order to find potential customers that are likely to become paying customers, advertisers can also use geo-targeting. Basically, geo-targeting is a method that enables advertisers to focus their marketing campaigns on certain regions. This way, they are focusing only on the group of people from a certain area, rather than promoting their product/service in every part of the world.
