Geotagging refers to the embedding of geographical data (like latitude and longitude coordinates) into various media formats including photographs, videos, websites, and SMS messages. This data indicates the precise location where the media was created or is relevant. In digital marketing, geotagging can enhance local SEO, as it allows search engines to associate web content with specific geographic locations, making it more likely to appear in local search results. It's particularly useful for businesses targeting local customers or operating in specific geographical areas.
