To add a link in your bio on TikTok, you typically need to meet certain requirements. While these requirements can change over time, as of September 2021, TikTok allows accounts with at least 1,000 followers to include a clickable link in their bio. This feature is not available to all users by default and reaching the follower threshold is necessary to unlock it. Once you meet this requirement, you can edit your profile and add your Hopp link to direct your followers to external websites or content.
