Instagram allows users to share photos and apply filters to give photos a professional look. Facebook acquired Instagram in 2012. Hashtags help organize content on social media by topic or keyword. Users should include relevant hashtags but avoid overusing hashtags or using the same hashtag multiple times in a post. Hashtags increase exposure for posts and help users engage with others interested in similar topics. Real estate agents can use location-based hashtags to promote listings and connect with potential buyers searching by location.
