clik.bio is a microblogging service on which users post and interact with micro-sites known as “bios“. Registered or invited readers can access the bios using a short-link. Typically, a bio contains information related to a person such as contact details, a playlist, or generally, any link that the creator and reader may be interested in.

Bios are frequently used to do business online since the creator can validate their bios and identity by linking their social networks, invite a reader to sign a document, or ask to join a conference without the complexity of managing multiple email notifications.
