Hello, I'm Geoff. TikTok, Instagram and most social media platforms only allow you to add one link in your profile bio. If you create a Bigger.Bio profile ( like this one ). Your Bigger.Bio profile can list an unlimited number of links to all your social media , websites, emails etc. Simply add your Bigger.Bio profile as the main link in your TikTok, Instagram, Snapchat and all your social media profiles and you can cross promote from each platform and get more followers. Enjoy!
