To locate someone on social media, start by searching their full name on platforms like Facebook, Instagram, Twitter, and LinkedIn. If the name is common, refine your search by adding their location, workplace, or school. Use search engines like Google with their name and keywords like "profile" or "social media." Reverse image searches can help if you have their photo. Specialized people-finder websites and mutual connections may also provide leads. Adjust privacy settings if needed. These methods can help you find people online efficiently while respecting privacy boundaries. Always ensure ethical and legal searches when locating someone.
