If you want to add a link to your bio on TikTok, there are a few things you need to know. First, open the app and go to your profile. Next, tap on the three lines in the top left corner of the screen. From here, you can edit your biography and add a link. To add a link, first make sure that you have the correct URL for your bio. If you’re using a personal website or blog, enter the full URL (including http://). If you’re using an external service like LinkedIn or Twitter, just type in the short domain name (like tiktok.com) without the http:// part. Next, type in your link text and hit “copy”. Now go to where you want your link to appear on TikTok (usually at the bottom of your bio), and paste in your copied link text. Finally, hit “save” and congratulations—you’ve added a link to your bio! ..
