A bundle takes several links and wraps them behind a single short URL. When someone opens it, they land on a clean page that lists every destination you added — with titles, descriptions and icons. One link in your bio can point to your shop, your latest post, your newsletter and your booking page at once.
A link that lives forever is not always what you want. A flash sale ends Friday. A webinar replay is available for 48 hours. A beta invite is for the first 100 people. Link expiration lets a short link switch itself off automatically when its job is done.
Sometimes a link is meant for a small audience: a draft page, an internal document, a client preview, a members-only resource. A password-protected short link puts a gate in front of the destination. Visitors see a simple password form before they are forwarded.
A custom domain lets you publish short links under a name you own, for example go.yourbrand.com/sale instead of teilen.bio/sale. The link still uses our redirect and analytics engine, but the surface is 100% your brand.
A custom alias is the word that comes after the slash. Instead of teilen.bio/x7K2p you publish teilen.bio/summer-sale. It is a small change with a big effect: people read it, remember it and trust it.
A URL shortener takes a long web address and replaces it with a compact one that points to the same destination. Instead of pasting a 200-character tracking link full of parameters, you share something like teilen.bio/launch. The result looks cleaner, fits anywhere, and tells the platform exactly who clicked.
