If you’re a TikTok user, you can add a link to your bio on the app. This will allow other users to find out more about you and see what kind of content you’ve shared on the app. To do this, open up the app and select “My Profile.” Then, under “Bio,” click on the “Add Bio” button. Enter in a brief description of yourself and your work or projects. Once you’ve finished, click on the “Save” button to add your bio to your profile.
