Geo-targeting, also known as geographic targeting, is a technique used in the online advertising industry to deliver ads to users based on their geographic location. Geo-targeting can be achieved through a variety of means, such as IP address, GPS coordinates, or zip code. Geo-targeting allows advertisers to target their ads to specific regions, cities, or neighborhoods, and to tailor their ads to the specific needs and interests of users in those locations. Geo-targeting can be an effective way to increase the relevance and effectiveness of an advertising campaign, as it allows advertisers to reach users who are likely to be interested in their products or services. However, geo-targeting can also raise privacy concerns, as it involves the collection and use of personal data.
