A bio link is the clickable URL placed in the bio section of a social media profile. On platforms like Instagram and TikTok, it’s often the only place where a clickable link is permitted, making it prime real estate for directing followers to a website, product page, or newsletter sign-up.
Because one URL can only go so far, many creators and brands use a link-in-bio tool to host a small landing page behind that single link - effectively turning it into a menu of destinations. The phrase “link in bio” has become a standard call-to-action in captions and stories.
