Link in bio
A link-in-bio page is a single web page that gathers a person's or brand's important links so they can be placed in a social profile that allows only one.
How it works
These pages often list a creator's other profiles, a shop, a booking link and a contact address, which makes them a handy public source of business contact details.
Reading one is reading a public web page, so a lookup returns the same links and contact details any visitor sees.
