A sponsored geofilter is a digital overlay that can be applied to photos or videos taken within a specific geographic location, typically used on social media platforms. These filters are created and paid for by businesses or organizations to promote their brand or event to users in a specific area. They often feature custom designs, logos, or slogans and are only available for use within the designated location. Sponsored geofilters are a popular form of targeted advertising, allowing companies to reach a specific audience in a specific location in a creative and interactive way.
