Do not require location-based services on your website, blog, or other digital media, but do allow them. According to Pew Internet, “28% of American adults use mobile and social location-based services.” If you want to include location-based services in your website, blog, or other digital media, do so. But do not require your users to employ location-based services. Since only slightly more than a quarter of American adult use these services, requiring location-based services will only limit your users (by about 72%). Make using location-based services easy for users new to them, but offer rich alternatives for users who do not want to use location-based services.
