X's Built-In t.co Shortener
Whatever URL you paste in X's Website field gets auto-wrapped through t.co. Display shows ~23 chars (e.g., t.co/abc123xyz), but the underlying URL is still your full original.
Caveat: The Website field has a 100-character storage limit. If your URL exceeds that, you can't paste it in. Shorten first.

Why Shorten if X Already Auto-Shortens via t.co?

- Click tracking outside X. t.co tracks for X; Bitly etc. give you your own dashboards.
- Editable destinations. Premium shorteners let you change destination without changing the URL itself.
- Branded look. Custom domain shortener (brand.co/spring) is more trust-building than t.co.
Shortener vs Bio Link Tool
