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.
Why the alias matters
The alias is the only part of a short link a human actually reads. A random string says nothing; a relevant word tells the reader exactly where they are going. Branded aliases are clicked more often, shared more willingly and look professional in print.
Good vs bad aliases
- Bad:
teilen.bio/a8f2kq— meaningless. - Bad:
teilen.bio/click-here-for-our-new-summer-collection-2026— too long. - Good:
teilen.bio/summer-sale— short, readable, on-brand. - Good:
teilen.bio/menu— perfect for a restaurant QR code.
Rules that work
Keep it under 15 characters, use hyphens instead of spaces, avoid special characters, and make it describe the destination. Reuse memorable aliases for evergreen content (your menu, your booking page) so the same short link keeps working.
Plan limits
Free accounts use random aliases. Starter gives you 5 custom aliases, Pro 50, Business 50. Combine aliases with a custom domain and every link becomes fully on-brand. Compare plans.
