Even major corporations such as Qantas Airlines, Red Bull, and the Los Angeles Clippers have started putting a Linktree in their Instagram and TikTok bios, Anthony Zaccaria, Linktree’s co-founder and chief commercial officer, told me. These companies all have expensive websites, but he said that link-in-bios have come to represent a space in between social media and websites: a regularly updated page where artists can plug their new music, airlines can promote their new flight routes, and even non-influencers can list out the TV shows they’re currently watching. While a traditional website might remain relatively static over time—an airline like Qantas, for instance, is always going to want its flight-booking tool to be front and center—a link-in-bio is a sort of ever-shifting homepage, the ideal spot for brands and influencers to house updates or tout new products.
